Temporary Tattoos May One Day Power Your Wearable Medical Devices
If you’ve ever been hooked up to a wearable machine at a doctor’s office, then you’re familiar with the electrodes that are attached to your body to monitor its electrical signals. The problem with these prefabricated metal-based or hydrogel electrodes is that they don’t always stay in place during movement, for long periods or on sweaty or hairy skin.
Penn State University engineers aim to change this with paint-on tattoos that use conductive ink to power sensors for wearable devices such as EEGs, ECGs and EMGs that track brain, heart and muscle activity, respectively.
As reported in a paper published Monday in the Proceedings of the National Academy of Sciences, the engineering team filed a provisional patent for this ink, a water-based solution mixed with polymers and acidic additives that starts out transparent with a glue-like consistency. It can be pigmented with food dye to create different colors for a cute fox or shark that opens its mouth when you open your hand, and it dries on the skin in under 10 minutes. It can later be reapplied or washed off.
Thanks to its customizable, fun nature, these paintable electrodes could be especially beneficial for children who may be more likely to wear a medical device if it’s powered by a temporary tattoo of their favorite character or animal.
Thanks to its customizable nature, the ink can be used like face paint for any design you desire.
How the ink powers wearable devices
To connect the ink to sensors, there’s a porous silver textile with connective electrodes. Before your painted-on tattoo dries, the textile is placed on the design so that it will stick to the skin. Then, the textile is connected to a port on a wearable monitoring device. The latter is taped to the skin beneath clothing.
Electrical signals collected by the ink are sent through the textile to the monitoring device, which then transmits the data to a computer via Bluetooth.
When the conductive ink is paired with a silver textile, it can be attached to a wearable medical device.
“The big idea behind this is that in the future, you could potentially have a more expensive sensing module that remains separate from the system, but the electrodes themselves can be disposable. A single bottle of ink could provide enough material to paint multiple electrodes over the course of several days or a week,” said Larry Cheng, the paper’s corresponding author and a James L. Henderson Jr. memorial professor of engineering science and mechanics at Penn State, in a press release.
The hope is that these temporary electrode tattoos can help spot heart attacks early, read brain waves or power robotic prosthetics.
Plus, since it’s painted directly onto the skin, the ink is more durable and accurate than sensors attached to the skin, as there may be an air gap between them and the skin. As for the silver textile, because it’s porous, its connective electrodes can expand to over 150% their original size. This means sweat can pass through the textile without negatively impacting adhesion, accuracy or comfort.
What the team found during testing
When experimenting with the ink, the Penn State team found that the painted electrodes could monitor ECG signals for up to 12 hours. They also stayed on during exercise. When applied to a team member’s forearm, the electrodes successfully tracked muscle signals using an EMG device, enabling remote control of a robotic hand.
Using an EMG device, a person’s muscle signals can be monitored to control a robotic hand.
Since the electrodes can be washed off and reapplied, 12 hours isn’t the limit for their use.
Eventually, the painted electrodes could even power sensors that track cortisol or glucose. The team is also looking toward commercial use for doctors, such as pediatricians. Or, to create “smart plants” that provide information on chemical exposure in their environment and its impact on plant health.
Just like it’s become normal to see people wearing health tracking smartwatches and smart rings, perhaps one day no one will bat an eye when they see someone leaving a doctor’s office with a temporary tattoo.

Outernet turns your saved posts into real-world adventures
Danielle Egan and Athena Leong know how to have fun. Between the two of them, they’ve organized a citywide scavenger hunt in San Francisco and turned a viral prank into an exclusive NYC restaurant for a night. They even created an alternative to a running club for socializing, dubbed a “sit club,” where people just bring their chairs and relax. Now, with their new startup, Outernet, the co-founders want to help others add more fun to their lives, too.
The app’s name is inspired by the concept of using the internet as a tool to get you to go outside, hence “outernet.” It’s one of several apps that helps you save the things you see online — like local events, restaurants or bars to try, or other city landmarks — and turn them into a list of to-dos for exploring the world around you.
Outernet’s pitch is that instead of simply liking a post about something you’d like to see or do on social media, you should share it to its app, where it will track the activity or place you want to visit for you in an organized interface. (Invite codes to try the app for yourself are at the bottom of this post).
What makes Outernet different from others in the space, like Albo, Tabi, or Plotline, is who’s behind it: founders who have devoted much of their time to playfulness and having fun offline. Now, they want to bring that same spirit into their app.

“In my free time, I’m very passionate about getting people to go outside and do things,” explains Egan, whose offline persona is quite different from her former day job working in product BizOps at LinkedIn. “I just love capturing attention in unexpected ways and delivering delightful things.” She says the thesis behind the app is becoming the “motivation engine for IRL” — something that removes the friction between wanting to do something and actually going out to do it.
Outernet taps into an already common consumer behavior. As you scroll TikTok and Instagram, you’re often inspired by a creator’s post, so you’ll save it in the app as a reminder. But then you promptly forget about the idea as you continue to consume more content. Outernet solves this problem by keeping track of the things you want to do or places you want to visit, all in one place.

To save a post to the app, you’ll tap the share option from the source app, like TikTok or Instagram, then scroll through the list of places you can share to until you find Outernet. You can also paste in social media URLs or website links directly into the app, or upload a photo of something you see, like a flyer.
To organize everything, Outernet leverages AI to pull relevant information, like the date, time, location, and details about the activity you want to try or the location of a place you’d like to visit. Events are saved to a chronological feed, which you can revisit whenever you’re looking for something to do. Other activities without a date, as well as places you’d like to visit, are organized into separate tabs within the app. You can also save events to your Apple or Google Calendar or view them in Outernet’s map.

The app can also send proactive reminders and nudges that encourage you to go do the things you’ve saved.
Then, as you explore places in the real world, you can “stamp” them as such, building what will eventually become a passport documenting your activities.

“We’re thinking of different ways of creating maybe some sort of like passport book where you can look at all the things [you’ve done] and maybe share that with friends and get some sort of sense of pride of that,” Egan says of future product plans. They’re also thinking of using traditional gamification techniques to encourage activity, like giving out stamps when you reach different milestones.
The idea for Outernet came out of the co-founders’ experience designing a citywide scavenger hunt in San Francisco, called “Pursuit,” which began three years ago and is now held annually. The monthlong game drew participation from about 1.5% of San Francisco’s population during its most recent run.
As the founders chatted with participants, they found that people didn’t get involved because they loved scavenger hunts or adventure games; they just wanted an excuse to go outside. This sparked an idea.
“We just realized that people really have an appetite for doing things, like going on adventures. This is the new trend,” notes Leong, whose background is in computer science and child development, before she landed a job in adventure game design.
“There are so many incredible community events, and being community organizers ourselves, we’re very plugged into that scene,” Egan adds. “What’s so hard is there are these boots on the ground — incredible community organizers who are hosting these amazing events, and they just don’t know how to reach people because marketing and grabbing people’s attention is such a different skill set. And that’s something that we are exceptional in. So we see ourselves as the conduit,” she says.
Outernet’s app has been on the market for roughly two months and is already profitable from its premium subscription ($6.99/mo or $39.99/year), which lets you save more items per day. It has around 18,000 users in total, and the team is experimenting rapidly with new ideas.
The founders are now having casual conversations with investors about their next steps, but finding the right fit is key.
“We want to bring on investors — if we do — [who are] people who are really aligned with us,” says Leong. “We’re whimsical, and we have to find investors that match.”
Outernet is invite-only and available on iOS, with an Android waitlist. TechCrunch readers can use the invite code “coffeewalk” to skip the waitlist.

5 STIHL Tools & Products You Probably Didn’t Realize Existed
A chainsaw is one of those essential yard tools that homeowners may not realize they really need until they actually do need one. If you’d prefer not to wait until you’ve got a yard full of fallen branches that need cutting down to see the need for a good chainsaw, they are easy enough to come by in the consumer market, with several major manufacturers putting their logos on quality devices these days.
There are so many options that it may be tough for some to determine which brand is most worthy of their hard earned money. But those who do even a little bit of research in the chainsaw market will learn with a quickness that Stihl is widely regarded as one of the best brands in the powered cutting tool game. If you’re interested in procuring a Stihl chainsaw for yourself, the brand currently features models to suit virtually any need in its online marketplace.
While you’re perusing those options, you might want to consider checking out some of the other tools and gear featured on the site, because Stihl has stretched its range of offerings well beyond just high-powered chainsaws. In fact, Stihl likely has a handful of powered and non-powered products available that even its most devoted fans had no idea even existed. Here’s a few you might genuinely be surprised to find among Stihl’s offerings.
Sprayers and misters
Apart from its well-regarded chainsaws, Stihl does indeed manufacture many other products fit for use by backyard DIYers and pro yard crews alike. That list includes mainstays like trimmers, pruners, blowers, and mowers. You may not realize it, but that list also includes a few more specialized tools like sprayers and misters.
If you’re unfamiliar with those devices, they are typically used to disseminate chemicals that help control pests, weeds, and fungi in your green spaces, as well as life-giving water and fertilizers. Sprayers tend to work better for focused coverage, while those with misting features are ideal for covering larger areas. At present, Stihl has 11 sprayers and misters listed among its online offerings, with styles ranging from non-powered handheld models, to backpack style builds that run on gasoline or lithium ion power.
Those sprayers vary dramatically in price, with the cheapest handheld model selling for $26.99 and the gas-powered S450 Backpack build listed for $859.99. Between those two models and the range of makes in between, Stihl seems to offer a sprayer that can meet the needs of most consumers. User ratings are not entirely encouraging for many of the models, however, so you’ll want to be sure to do your research before you purchase one.
Axes, Mauls, and other woodcutting gear
The Stihl brand has long-been been recognized as one of the preeminent manufacturers of powered chainsaws. As such, the family-owned outfit has, historically, focused the bulk of its production on gas and battery powered cutting tools. Given the company’s general market focus, you might be surprised to learn that Stihl also offers several non-powered woodcutting tools, including both axes and mauls.
For those who may not be in the know, even as those tools bear a striking resemblance to each other, they are designed for decidedly different purposes. To break it down simply, traditional axes are designed with a slim head to cut across wood fibers to more efficiently bring down trees and limbs of various sizes. A maul, on the other hand, is designed with a heavier, wedge-shaped head that makes it ideal for splitting logs. Whichever of those tools you might need, Stihl surprisingly offers multiple models of each online, ranging in price from $37.99 to $119.99. The brand also offers a 19.75-inch hatchet for $66.99 if you need one of those.
Perhaps more surprisingly, Stihl even features several logging accessories among its woodcutting wares. That includes various log-moving tools like a Cant Hook, a Log Carrier, and a Hookaroon.
Sweeping machine
For the sake of being fully transparent, we can tell you that, prior to coming across the tool on Stihl’s website, we were not really aware that sweeping machines were even a thing. They are. And as surprised as we were to learn that, we were even more surprised that Stihl actually makes one.
If you’re as uninformed as us on sweeping machines, you might now be wondering what, exactly, one does. Turns out that the name is pretty self explanatory — a sweeping machine is basically designed to be a sort of street sweeper for sidewalks, smaller hardscaped areas, and some home interiors. They look a lot like a lawn mower, except that the front end is equipped with spinning brushes that collect leaves and debris as the sweeper passes over them. The device is, of course, powered, and designed to run on Stihl’s AP 300 S lithium-ion battery.
According to the listing for Stihl’s Sweeping Machine, the sticker price includes neither the necessary battery or a charger. Given that it’s priced at $1039.99, that exclusion may be a deal breaker for some, particularly as the sweeping machine will likely be viewed as a luxury addition to most yard care routines. If you can afford it, however, the sweeping machine may be a luxury worth having.
Smart tool accessories
We are officially living in the age of the smart device, with the term being applied to everything from the phones in our pocket to the appliances in our kitchen. Given the fact, it’s only natural that the smart device craze has made its way into the power tool arena, with companies like DeWalt utilizing Bluetooth capabilities for its Tool Connect system.
Several of the other major players in the power tool market have followed suit, and Stihl is very much among them. At present, the brand features just two smart devices on its website — the Smart Connector and the Stihl Connected Hub. The former tool is, in essence, a smart tag tracker that can be attached to any Stihl tool. Once in place, the tag — which picks up on motor-generated electromagnetic fields — can transmit data to the Stihl app, allowing you to track a device’s runtime, performance, and, perhaps more importantly, its location.
Meanwhile, the Hub does exactly what you’d expect a hub to do, which is collect that Smart Connector information on a scale more befitting an entire fleet of tools, then storing it in the Stihl Cloud for easy user access. Stihl’s smart devices are priced at $203.99 and $235.99, respectively.
Inflators and Compressors
Even as advancements have been made regarding inflatable items, car tires, bike tires, and soccer balls still regularly turn up in need of air. While hand pumps are capable of filling those items with the requisite air they need to function, they are hardly convenient, and in the case of a car tire, may not properly do the job. As such, electric inflators have become all the rage among many of the major tool makers out there.
Yes, Stihl has indeed joined the inflator fray, offering a single battery-powered model among its tools. That inflator is the KOA 20, which is currently selling for $119.99 in tool-only format. If you’re looking to add the inflator to your garage setup, which requires an AS 2 battery and the AL 1 charger to power it, Stihl sells a kit with all three for $199.99.
Those prices are, more or less, on par with what you’ll find among inflators from some of the other major brands, and for what it’s worth, Stihl customers seem to be plenty impressed with the KOA 20 — which is IPX-4 rated for weather resistance and can also deflate items to desired pressures — rating it at five out of five stars on its product page.

Simulation Apps Pinpoint Cause of Electronics Failures
This article is brought to you by COMSOL.
In pursuit of improved range, greater reliability, and faster charging, electric vehicles are driving the demand for high-voltage electronics. Other applications driving this demand include wind farms, data centers, and server farms, to name a few. As the interest for high-voltage electronics increases, the risks associated with their sudden failure must be considered.
Much of what causes high-voltage equipment to malfunction can be linked to the conditions of the climate in which it operates. Specifically, condensation on electronic surfaces caused by humidity can lead to corrosion, which can result in stray leak current and dendrite shorting during Electrochemical Migration (ECM).
Predicting, mitigating, and helping proactively design to account for corrosion is the focus of the Centre for Electronic Corrosion (CELCORR) research group at the Technical University of Denmark (DTU). The group’s researchers are working with industry partners to develop models and simulation apps that will help in building robust electronics designs. Their goal is to develop knowledge that can be used for manufacturing electronics to withstand humid operating conditions.
Electronic Failure: “It’s Not the Heat; It is the Humidity”
Automotive electrification and renewable energy systems rely on electronics at all stages of the energy chain. When these electronics, such as the example PCB in Figure 1, are exposed to the effects of moisture, they can become potential failure points.
“Anywhere you are producing, converting, transporting, and using energy, you need these high-power electronic systems that get affected by the humidity,” explained Dr. Rajan Ambat, DTU professor and manager of CELCORR. Ambient moisture can seep into the devices and machines that require these electronics and cause unexpected functional issues through corrosion. When these electronics are involved in particularly high-voltage applications (such as wind farms, data centers, electric vehicles, and server farms), failure due to humidity exposure can even lead to fire.
“There might be a situation where somebody installs a solar panel near the seashore or in an area with high humidity, and within a short period of time, a conducive condition forms inside the electronics that results in a failure,” Ambat said. “This is why we need to understand exactly how the conducive condition of condensation is created, when the condition is created, and how the system is failing.”
Figure 1. The electrolyte potential and current density distributions on a PCB surface (with pinholes).CELCORR/DTU
Identifying corrosion as the underlying cause of some electronic failures is still a challenge. “Fifty percent of failures in electronics are currently branded with an unidentified root cause,” Ambat explained. “When engineers open up the system, they do not realize that the failure was due to corrosion, because moisture disappears without leaving any sign of corrosion unless there is ECM dendrite formation.”
This lack of awareness was a strong motivator for CELCORR, which turned to multiphysics simulation as a supplementary tool to help its partner organizations to better predict humidity-related issues at the design stage.
Modeling Moisture and Measuring Parameter Changes in PCBs
CELCORR believes the best way to identify and avoid electronic failures is to build more effective designs that better prevent corrosion from developing or can withstand a higher humidity load. Its research team applies its expertise in modeling to generate simulation apps that will help partner industries to evaluate safe designs for humidity robustness.
“We are at the intersection of materials science and the electronics industry. We work as a bridge between materials and electronics disciplines, using both kinds of language,” Dr. Anish Rao Lakkaraju, a postdoctoral researcher at CELCORR, explained.
To understand potential design issues, Ambat emphasized the importance of virtually breaking down systems to identify where problems may arise. “We need simulation software to analyze potential uses of designs and whether new designs are good or bad,” Ambat said.
Researchers at the Technical University of Denmark (DTU) are using simulation apps to predict corrosion and design electronics proactively to mitigate or withstand its effects.
Using the COMSOL Multiphysics software for investigation, the CELCORR research team together with other research partners (Aalborg University) built an example model with a simple PCB geometry that matched both its test circuit boards as well as the design of a device used by one of its partner companies. The team then added a water film layer on top to act as the relative humidity. From there, the team could introduce variation. “We change the layout, geometry, distance between electrodes, thickness of the water film, and conductivity of the water film depending on the conditions,” Ambat said.
Ambat and his team generate data on the effect of these variations and can identify which has the greatest impact on the device’s performance and whether any alterations can improve the device’s anticorrosion robustness. “We assume there is condensation forming on the electronic surfaces (Figure 2) and compute the electrochemical leak current for different design elements,” Ambat said. “The value of the computed electrochemical current between the parts will give us an indication of whether the PCB will be affected or not.”
Figure 2. A 10-µm water film condensation effect on an example PCB.CELCORR/DTU
Altering the design elements and solving the model equations again and again allows the team to better understand what makes a design effective. “Now, we are at the current form of the model, and we are quite happy with where the physics are at this point,” Lakkaraju said. This modeling, however, was just the first part of CELCORR’s overarching goal of illuminating the destructive potential of corrosion in electronics and the best ways to avoid it.
Using Simulation Apps to Test Real-World Designs
To open up and ease access to these models, CELCORR used the Application Builder in COMSOL Multiphysics to create simulation applications for the members of the industrial consortium. Built with a simple 3D circuit board geometry with two oppositely biased electrodes and a water layer to replicate corrosion-causing moisture, the apps provide a pared-back, straightforward interface where users can vary model inputs. “We focused on fundamental aspects,” Lakkaraju said. “We boiled down our partners’ overarching concerns to create two apps with very simple geometries and the simplistic stuff that can be varied over multiple parameters.”
The simple simulation apps shown in Figures 3 and 4 are designed to show companies how the distance between the electrodes and the thickness of the moisture layer affect the leak current through the water film depending on different parameters. By analyzing multiple design elements and parameters, users can determine the relative benefits of certain design elements on the humidity robustness. “The apps we have built have really helped because they give the electronics engineers a plug-and-play sort of approach,” Lakkaraju explained.

“By using this app [Figure 3], companies have unlimited freedom to work with these sorts of variables,” Lakkaraju added. “This would be quite difficult to recreate in real life with physical design and testing, and the companies we work with are quite happy with the level of accuracy the app can provide.”

Looking Forward: Complex, High-Voltage Modeling
Alongside its collaboration with the industry consortium, CELCORR is also working toward improving the world’s general understanding of corrosion’s impact on electronics. To do this, Ambat and his team are undertaking multiple projects, including actively adding greater complexity to their models. In a tertiary current distribution model they are building, the team is drilling down into each of the basic inputs used in a secondary current distribution model, zooming in to examine the effects of the set of even more detailed inputs each basic input comprises.
“The next point is to study what each of these detailed inputs does,” Lakkaraju said. In particular, the team is examining mass transport properties and the chemical reactions’ rate constants.
In addition to these ongoing studies, CELCORR is expanding the scope of its research to investigate corrosion in high-power, high-voltage systems. Thanks to a 2024 grant from the Grundfos Foundation, CELCORR was able to establish the Centre for Climate Robust Electronics Design (CRED). The center’s lab facilities and expertise are being developed to address the humidity-robustness requirements of today’s high-voltage and high-power electronic equipment. “Using CELCORR’s uniquely deep understanding of materials and corrosion, we are equipped to find the root cause and provide knowledge for environmentally robust designs,” said Ambat.
For all of its investigation, CELCORR continues to rely on the agility of the COMSOL Multiphysics software. As Lakkaraju explained, “It is really quite nice how a model can be adapted to a variety of combinations of materials, geometries, and parameters and how the software allows you to keep building on from there.”

Sequoia’s Shaun Maguire leads $1B round for nuclear startup Valar Atomics
Valar Atomics confirmed the whisperings that it was raising a giant round led by Sequoia on Monday. The startup’s founder and CEO Isaiah Taylor announced that the company has raised $1 billion in equity, with Sequoia partner Shaun Maguire joining its board, and that it also secured a $200 million line of credit from Erebor and other banks.
While the nuclear startup did not disclose its valuation, Bloomberg reported that it was $6 billion.
Valar is building small modular nuclear reactors (SMRs) — essentially miniaturized, factory-built power plants intended to be cheaper and faster to build than traditional reactors. In June, it demonstrated its Ward 250 reactor successfully powering an Nvidia Blackwell system, the company said, and announced a deal with Nvidia to develop a waterless 30MW AI factory.
Valar says its reactors generate the engineering, manufacturing, and operational data needed to improve next-generation reactors, speeding its development cycles.
“It took two years to complete the NOVA core. It took seven months to take Ward 250 critical. With each reactor built, the tick rate will become smaller until Valar is producing tens, then hundreds, then thousands of reactors per year,” it said, adding that this funding will allow it to reach to its next milestone: manufacturing fleets of its SMRs.
It certainly isn’t the only nuclear startup pursuing such ambitions. Over the past few months, Antares raised $470 million, and X-energy raised $1 billion through its IPO.
As for Valar’s new round, other investors include Apandion Capital, Atreides Management, Conviction, Dream Ventures, HOF Capital, Point72 Ventures, Riot Ventures, Snowpoint Ventures, and Valor Equity Partners.

India plans more tax breaks to sweeten Apple’s iPhone production
Apple’s iPhone production in India is getting more of a boost, as the government considers extending a tax exemption on manufacturing machinery and component imports until 2041.
India is a major location in Apple’s work to diversify its production outside of China. While it has already benefited from many incentives from the country, its supply chain stands to benefit even more.
A draft proposal seen by Reuters affects a tax exemption that India introduced in February. That incentive, applicable to foreign companies, was introduced after Apple lobbied against being taxed for iPhone machinery it owned in India but provided to contract manufacturers.
Under the original incentive, it was set to expire in 2031. Under the proposals, it would instead run until 2041.
At this time, the draft proposal still needs to pass through both houses of Parliament for approval, in a process that can take months, if not years.
Beyond machinery
The proposals don’t just extend the period of exemption on taxes for machinery. It also extends into the realm of component storage with regard to exports.
India will also exempt foreign companies from being taxed for storing and shipping parts used to manufacture components and products. However, only for hardware that is not intended for sale in India.
Instead, factories and warehouses would have to set up in customs-bonded areas. This refers to regions that are considered to be outside India’s customs border for taxation purposes.
Items imported and stored in these areas would not be subject to import taxes. That is, so long as the products and components made with them are then exported out of the country.
If those items are then sold within India, they would be subject to import taxes as normal.
For Apple, the change would be beneficial, since it wouldn’t pay import duties. The intention is to make India more attractive for producing iPhones intended for exports.
Apple already benefits from import duty cuts on July 9, affecting select components used to produce smartphones. The proposed change will bring those same taxes down to zero, for export-only production.
Data storage
While the bulk of the proposals surround manufacturing, there’s also some relating to another kind of storage. That of data.
In February, India introduced a tax exemption for foreign companies using data centers in the country, for providing services to users around the world. That tax exemption lasts until 2047.
However, the proposal extends the exemption to allow those data centers to be leased by Indian partners, rather than be owned outright. The change means it will lower the capital requirements for Indian partners, opening it up to smaller and mid-sized firms.
To Apple, it means a bit more flexibility if it wants to set up data centers in the country.

How NTT DATA AIVista closes the last mile of agentic AI for enterprise agents
Presented by NTT DATA AIVista
At VB Transform 2026, NTT DATA AIVista CEO Bratin Saha joined VentureBeat CEO and editor-in-chief Matt Marshall to discuss the last-mile challenge of operationalizing frontier models in regulated production, where reliability, context, guardrails, and security determine whether AI delivers enterprise value. The conversation centered around the question facing every enterprise now pouring money into AI: how to convert that spending into real, tangible value.
“It’s not just a model, you’re building a system around the model,” Saha said. The last mile is the work of wrapping a frontier model in an enterprise’s own data, workflows, and guardrails.
In the end, regulated production turns on more than just technology, Saha said. Today, most enterprise AI projects fail during implementation because of poor integration, domain specialization gaps, lack of governance, and unclear ownership of outcomes. Last-mile specialization turns a capable foundation model into an enterprise agent shaped by domain-specific workflows, risk appetite, client classifications, regulatory interpretations, and institutional knowledge.
Why frontier models stall in enterprise workflows
Frontier models fall well short of production-grade accuracy on many real-world insurance workflows, Saha said, but last-mile specialization can lift them to the reliability enterprises need. Out of the box, those models struggle with the complexity of regulated workflows such as multinational insurance claims.
“These forms are pretty complex, often have handwriting, lots of checkboxes, and so on,” he said, and that complexity is why frontier models like Fable 5, Opus 4.8, and GPT-5.5 fall short out of the box.
Saha said the biggest gains come from specializing the entire AI system, not just the foundation model.
That system gets specialized with the customer’s data, workflow and, in many cases, the tribal knowledge that never made it into an operating procedure document.
“The biggest bang for the buck comes from the specialization and then these specialized guardrails,” he said.
The work has three components:
capturing the enterprise’s context and making it consumable by AI
running an ensemble of models so cost does not go through the roof
and adding specialized guardrails that check the model and force a redo when it gets something wrong.
What the last mile of agentic AI actually requires
None of this involves fine-tuning. VentureBeat’s latest enterprise survey found it ranked last among companies’ model-selection priorities.
Instead, the last mile centers on domain knowledge and undocumented workflows that companies would never expose publicly without losing their competitive edge.
“The last mile is about taking data that’s proprietary to you and using that to build a system around the model that can steer the model in the right way that can put the appropriate guardrails around it,” Saha said.
In the end, enterprise AI is about moving a workflow from point A to point B rather than deploying a technology, and NTT’s advantage comes from pairing AI experts with subject domain experts.
“The only reason is because we go and talk to those human workers and we say, ‘How do you actually do the work,’” he said. That expertise is then encoded into an agent.
Success in insurance, manufacturing, and other regulated industries relies on three things at once, he added.
“You need technology, you need the domain expertise, and you need the change management expertise,” he explained, adding that across his team’s clients, technology is not the bottleneck.
How enterprises turn AI investment into tangible value
For enterprises weighing large AI budgets, Saha’s said the payoff comes not from the model but from the work built around it.
“When you’re deploying AI in the enterprise, you’re not deploying a technology,” he said. “You are taking a workflow that exists and taking it from point A to point B.” The value is created by the workflow that gets moved, not the model that helps move it.
That reorders where money should go.
“Technology is not the bottleneck,” Saha said, pointing instead to the domain expertise and change management wrapped around the model, and to the discipline of commiting to all three together. Spending aimed only at the model leaves most of the return on the table.
Enterprises don’t have to choose between embedding AI into existing workflows and redesigning those workflows from scratch. NTT sees the two as successive stages of the same journey.
“We are starting with embedding in the workflow because it’s easier change management,” he said, noting that customers running mission-critical operations will not let a vendor rip out a working process midstream. “Once that happens, then we go into, how can we now reimagine this? And that really is where the biggest bang is.”
Where enterprise AI stays bespoke and where it becomes scalable
Keeping intelligence in the surrounding system rather than the model also preserves swappability and lets enterprises take advantage of open-weight and open-source models as they mature. Saha’s team runs an ensemble that mixes frontier and open-source models, and he expects the industry to lean on open weights wherever the cost of a mistake is low while reserving frontier reasoning for the cases that demand it.
“In many situations, especially in regulated industries where mistakes are very expensive, that last extra couple of percent matters,” he said.
The platform follows the same pattern: Guardrail generation and neurosymbolic models scale across customers, while capturing each organization’s tribal knowledge remains bespoke. Saha pointed to NTT DATA’s position as one of the world’s largest insurance third-party administrators as an advantage in acquiring that expertise.
“The ability to take that knowledge and trust that has been built over 20 years is very hard to replicate instantly, and I do think that is a durable aspect of what we have,” he said.

The Best Audio Players for Kids: Yoto, Toniebox, and More
In my current season of toddler parenthood, I’ve sometimes felt that I could cut the tension between myself and the TV remote with a knife. As much as I try to keep screen time in check, sometimes I need 10 uninterrupted minutes to unload the dishwasher before a certain almost-2-year-old goes for the dog bowl.
That’s where audio players are handy. In a world where screens are increasingly hard to avoid, parents are looking for alternatives—and these players, in their various formats, are to the rescue. The devices mark a sweet spot between independent play and story time, letting kids listen to music, audiobooks, and interactive stories without a tablet in sight. Some audio players are geared toward younger kiddos who enjoy tactile toys and familiar characters like Elmo and Bluey, while other options are designed to grow with them to chapter books, podcasts, and beyond.
Over the past several weeks, my family has tested some of the biggest names in the category to see how they stack up. Here’s the verdict on which ones are best suited for different families and their needs.
Want more recommendations for WIRED-tested kids’ toys? Here’s our guide to Brain-Boosting Toys for Kids, Kid-Approved STEM Toys, and the Best Gifts for Lego Lovers.
Best for Kids of All Ages
The Yoto Player is simple enough for toddlers to operate independently while offering a broad enough content library to keep it relevant as kids grow. Stories and music live on credit card–sized cards that my daughter could swap in and out with her little hands, and the small pixel display on the front of the machine adds a visual element without becoming another distracting screen.
You can add each Yoto card to your child’s library through the device’s companion app. Once you do, you can stream the content directly from your phone or remotely send it to the Yoto. That means you’re not necessarily tied to bringing the speaker with you everywhere you go. I saw this capability as being especially useful on road trips—you can play stories through your car speakers or listen from your phone if the player gets left behind or its battery dies.
Yoto offers more than the stories and songs from its player cards. You’ll also get kid-friendly daily radio, draw-alongs, toothbrush timers, white noise, a wake-up clock, and a nightlight that activates when you flip the player screen-side down. I only see it getting more useful as my daughter grows, and if I’m being honest, there is a Nancy Drew story collection I am secretly eyeing for myself.

Here’s Why You Shouldn’t Buy New Headphones Without Bluetooth Multipoint
The incredibly useful feature is only present in specific headphone and earbud models.
Bluetooth headphones have exploded in popularity, with the market continuing to grow each year. The category, which includes over-ear headphones like the Sony WH-1000XM6 and in-ear devices like Apple’s AirPods line, offers a mix of comfort and convenience, and we’ve reached a point where it’s hard to find name-brand headphones that don’t sound at least somewhat decent. But while most marketing for consumer-grade wireless headphones focuses on headline features like active noise canceling, there’s another feature most people should add to their list of non-negotiables.
Once upon a time, during the halcyon days of the ubiquitous headphone jack, swapping between devices was a matter of popping the plug out of one and into the other. Maybe you’d get an audio splitter if you really needed to use two audio sources at once, but that was as complicated as things usually got. With Bluetooth, simply switching even the best wireless headphones over to another device involves fiddling with settings menus and dealing with frustrating connection issues.
Finicky connections are a defining trait of the decades-old Bluetooth protocol, and although improvements continue to be made with each generational update, that essential character remains. That’s where Bluetooth multipoint comes in. It’s a feature that allows a Bluetooth device to remain connected to multiple devices at once, swapping between audio streams from each as you use them. While multipoint can introduce some annoyances of its own, it’s still far preferable to manually switching between devices over Bluetooth. Here’s why it’s a must-have for most headphone shoppers.
Bluetooth multipoint reduces friction for multi-device setups
Bluetooth multipoint is a manufacturer-introduced technology which can allow for a wireless audio device to maintain a connection to multiple audio sources. It usually allows for a connection to two devices, though there are exceptions. The feature is more common on high-end consumer headphones like the Sony WH-1000XM6, though it can sometimes be found on downrange products.
Your Bluetooth devices use different Bluetooth profiles for different types of audio. Music and other media streams use the A2DP profile. On certain devices, this can also transmit high-resolution wireless codecs like Qualcomm AptX and Sony LDAC. You may simultaneously use an AVRCP profile to send volume and play/pause commands to the host device. When you get a phone call, you’ll switch over to the lower-quality audio of the bidirectional HFP profile. When you’re listening to music on your laptop, you might get a phone call, and your headphones will prioritize the HFP connection to switch over. However, if you’re using HFP for a Zoom call, it may retain priority until you answer the incoming call.
Not all multipoint is made equal, and whether a particular implementation of it works for you depends on which devices you plan to use the headphones with. It’s a good idea to test the multipoint functionality of a pair of headphones before you buy them, if possible, to ensure that their multipoint implementation works well with your particular devices. If you can’t test that functionality before buying, do so before the return period ends.
Multipoint can create its own frustrations
Bluetooth multipoint can make it much easier to use multiple devices with a single pair of headphones, but it can also introduce new headaches. Multipoint is not part of the Bluetooth specification, and is instead implemented by device manufacturers on top of the Bluetooth stack. This explains why it remains a relative rarity despite consumer demand. The ability to handle multiple streams was added with Bluetooth 4.0, but multipoint features are logics built atop the Bluetooth protocol. Bluetooth cannot mux or sum together multiple audio streams, so multipoint does not allow a user to listen to audio from multiple devices at once. Instead, it decides which stream should take priority and pipes that to your ears, often pausing other media. Incoming phone calls usually demand precedence, for example.
Multipoint often assumes you’ll only use one device at a time, but try scrolling Instagram on your phone while listening to a podcast on your computer. As Instagram’s annoying autoplay causes the app to output audio, your multipoint headphones will divert away from your podcast. This will often happen even if your phone’s media volume is set to zero. Equally annoying notification dings on your phone may ride along on the same Bluetooth profile as phone calls, interrupting you with every group chat message.
Apple and Samsung have their own solution to this issue. Technically, the best AirPods and Galaxy Buds do have multipoint — a modified version designed to work exclusively with their own products. While often justifiably perceived as user-hostile, this approach can yield better Bluetooth switching results in normal use because the company controls the way Bluetooth is implemented on its headphones, phones and laptops, whereas companies like Sony or Bose do not have the benefit of bespoke ecosystems.
