A newly published US patent application from the company describes a smart ring built around that idea. It was filed in February 2025 and published on August 20, 2026 as US 2026/0246054 A1.

Anyone who has owned a smart ring for a few years will understand the problem. These devices are designed for continuous wear, but their batteries are usually permanently sealed inside. Once capacity drops significantly, replacing the battery is generally not practical and the entire ring can end up needing replacement.

Ultrahuman’s answer is to make the battery itself part of a removable section of the ring.

Swap the battery without stopping the ring

The drawings show a main ring body containing the sensors and electronics, with a curved battery section that attaches to it. Ultrahuman lists several possible ways of securing the two pieces, including magnets, a sliding lock and a snap-fit mechanism.

Electrical contacts automatically connect the battery module to the rest of the ring once it is attached. The patent mentions spring-loaded pins, pogo pins and magnetic contacts as possible approaches.

But the clever part is what happens when you take that battery out.

Ultrahuman proposes putting a smaller “residual battery” inside the main ring body. When the removable battery is detached, this smaller battery temporarily powers the sensors and electronics. Once a charged module is attached, a switching mechanism moves power back to the larger battery.

In theory, you could keep a second battery module charged and swap it in within seconds. The ring would continue recording while you do it, rather than spending an hour or two sitting on a charger. That is particularly interesting for sleep and recovery tracking, where missing chunks of data can affect the following day’s scores.

Oura has been thinking along similar lines

This isn’t the first removable smart ring battery design we’ve come across.

Earlier this year, we covered an Oura patent for a smart ring with a detachable battery section. Oura’s approach also separates the battery housing from the sensor-equipped portion of the ring, allowing the power module to be removed and replaced.

The two ideas attack much the same problem, although Ultrahuman’s residual battery makes its version particularly interesting. Instead of simply making the main battery replaceable, the filing is designed around keeping the ring operational during the swap.

That could also make charging work quite differently. Rather than charging the whole ring every few days, you could potentially charge individual battery modules separately and rotate them.

Battery ageing may be the bigger benefit

Convenience is only half the story. Replaceable batteries could substantially extend the useful life of smart rings.

I found battery performance pretty solid when I tested the Ultrahuman Ring Air, with the ring typically losing around 15 to 20% charge per day. But lithium batteries inevitably degrade with repeated charging cycles, regardless of how well they perform when new.

Ultrahuman explicitly talks about this in the filing. Instead of throwing away an otherwise functional ring when its battery deteriorates, the owner could simply replace the battery module. The company also suggests different battery capacities could eventually be offered, opening the possibility of choosing between a lighter module and one designed for longer runtime.

There is even an outer shell in some of the drawings that fits over the ring and removable battery section. This could be made from silicone, metal or a combination of materials, helping disguise the modular construction and making the finished device look more like a conventional ring.

None of this means Ultrahuman is about to launch such a product. Patent filings regularly cover ideas that never make it into commercial hardware, and making a removable section durable, waterproof and comfortable enough for continuous wear would bring its own engineering headaches.

But this is now at least the second major smart ring company we’ve seen exploring replaceable batteries. That makes the broader idea more interesting than any one patent.

The post Ultrahuman wants you to swap your smart ring battery in seconds appeared first on Gadgets & Wearables.

That could give a future Oura ring a way to get your attention while keeping the minimalist approach that has defined the product so far. More interestingly, Oura thinks the system could create several different sensations rather than simply producing the equivalent of a buzz.

A smart ring that electrically taps your finger

The patent, titled “Electrical stimulation for haptic feedback“, places several electrodes around the inside of the ring, with circuitry generating a controlled electrical current between selected electrodes and through the wearer’s finger.

This is not supposed to work like an electric shock. Oura describes carefully controlled pulse sequences where frequency, duration, current and other parameters can be adjusted to create different sensations.

Things get more unusual when the patent discusses nerve placement. Depending on which electrodes are used, the electrical path could intersect a nerve in the finger, meaning the wearer might feel the sensation farther along the finger or even at the fingertip rather than directly underneath the ring. 

Oura also discusses “biomimetic” stimulation patterns. In plain English, that means adjusting the pulses so they feel more like familiar sensations such as pressure or touch instead of an unnatural electrical sensation.

The strength and pattern could also be personalised. The ring could run test patterns, ask for feedback and then adjust the stimulation according to what the wearer finds comfortable and noticeable. 

This solves an interesting Oura problem

The idea is particularly relevant because Oura has traditionally avoided putting a vibration motor inside its rings. That simplicity has advantages, but it also means the ring cannot currently tap your finger when an alert arrives.

That difference has become more obvious as competing smart rings add haptics. The RingConn Gen 3, for example, includes vibration alerts, while Oura Ring 5 still goes without them.

Electrical stimulation gives Oura a different route. It could potentially provide discreet notifications without adopting exactly the same hardware approach as competitors.

The patent mentions health and wellbeing notifications, battery information and device settings as examples of information that could be communicated. Different electrical patterns could represent different alerts, so the wearer might eventually learn to distinguish them without looking at a phone. 

There is also some clever adaptation built into the concept. Oura proposes determining which finger the ring is being worn on and selecting the electrode pair most likely to produce the desired sensation on that finger. 

Oura is clearly thinking beyond passive tracking

The patent fits an interesting wider direction for smart rings. These devices have traditionally collected information quietly and then handed everything over to a smartphone app, but adding haptic output would turn the ring into a two-way interface.

Oura could use that for simple notifications, but health applications are potentially more interesting. A ring that detects a physiological change could theoretically alert the wearer directly instead of waiting for them to open the app.

The filing claims priority from February 4, 2025 and was published internationally on August 13, 2026. The international search report also cites earlier work relevant to several of the claims, which is a reason not to treat the application as a finished Oura technology. 

Even so, this is one of the more interesting Oura patents we have seen recently. Instead of simply finding another health metric to calculate, Oura is looking at changing what a smart ring can actually do on your finger.

We covered Zepp Health’s lawsuit when it was filed in April. At the time, it looked like the latest escalation in an increasingly messy smart ring patent fight, but that particular case ended rather abruptly.

Zepp dropped all six patent claims

Zepp Inc. and Zepp North America filed their lawsuit against Oura on April 21 in the Eastern District of Texas. The complaint accused the Oura Ring Gen 3, Gen 4 and accompanying app of infringing six Zepp patents covering areas including motion recognition, sensor confidence, stride calibration, health scoring and sleep monitoring.

Less than three months later, Zepp changed course.

On July 10, the company filed a notice voluntarily dismissing the entire case without prejudice. That last part means Zepp technically retains the ability to bring the claims again, rather than losing them through a court ruling. There was no decision on whether Oura actually infringed any of the patents.

Bloomberg Law reported the dismissal on July 13, but at that point the wider picture was not quite as clear. We now have another filing that helps explain what was happening behind the scenes.

Oura and Zepp had reached a settlement

A newer USITC notice published on August 12 confirms that Oura and Zepp had jointly asked to remove Zepp from Oura’s separate International Trade Commission case on July 9.

More importantly, the filing explicitly says the request was based on a settlement agreement.

The timeline is pretty telling. Oura and Zepp jointly asked the ITC to terminate Zepp from that investigation on July 9. The administrative law judge approved the request on July 10. Zepp then dismissed its own six-patent lawsuit against Oura on July 10 as well. The full ITC notice lays out the sequence of events.

The terms of the settlement have not been made public, so we cannot say exactly what each company agreed to. But given the timing, it looks very likely that Zepp’s decision to withdraw its lawsuit formed part of the broader settlement between the two companies.

That makes this more interesting than Zepp simply deciding not to pursue the case.

Oura originally went after Zepp Health over the Amazfit Helio Ring. Last November, it filed a patent lawsuit against Zepp Health and followed that with an ITC action seeking potential import restrictions against Zepp and several other smart ring companies.

Zepp then fired back in April with its own six-patent lawsuit against Oura. For a while, the two companies were effectively suing each other over different parts of their respective wearable technology portfolios.

That standoff has now cooled considerably.

The ITC formally terminated Zepp from Oura’s investigation following the settlement. The Commission confirmed that decision on August 11 and published its notice the following day. That means the Amazfit maker is no longer one of the respondents facing a potential exclusion order in that particular ITC case.

The smart ring patent war is changing shape

There is a slightly bigger story here as well. Oura has spent the past few years aggressively enforcing its smart ring patents, and we have seen disputes involving RingConn, Ultrahuman, Samsung, Zepp Health and others.

Some of those fights are now ending in settlements rather than courtroom victories.

That appears to be what happened with Zepp. Neither side got a public ruling declaring its patents stronger, nor did a court decide that either the Oura Ring or Amazfit Helio Ring infringed the other’s technology. Instead, the two companies appear to have found a way to remove Zepp from the ITC fight while Zepp simultaneously withdrew its offensive lawsuit.

There are still plenty of legal battles surrounding Oura. Samsung remains involved in substantial smart ring litigation, and Oura’s patent portfolio continues to face challenges in several venues. So this is certainly not the end of the broader smart ring patent war.

The post Oura and Zepp Health appear to have settled their smart ring patent battle appeared first on Gadgets & Wearables.

This is not Oura’s first move in this area. We have previously covered its more detailed work on cuffless blood pressure monitoring, where pulse timing, calibration and software processing played a central role. This new filing approaches the problem from another direction, focusing much more closely on the physical layout of the sensors inside the ring.

A different way of reading the pulse

The patent, called “Axial photodetector array for wearable ring devices“, was filed as an international PCT application from the US and published by the World Intellectual Property Organization (WIPO) on August 13, 2026. Rather than relying on photodetectors arranged only around the inner circumference of the ring, Oura proposes placing multiple detectors across its width as well.

This creates something useful. Two photodetectors sitting a known distance apart can pick up slightly different versions of the same pulse wave, including differences in timing and signal characteristics.

Oura describes comparing those measurements to calculate additional physiological information. In the claims, the company specifically names blood pressure, pulse wave velocity, arterial stiffness and blood viscosity as possible outputs. 

The diagrams in the filing make the idea easier to understand. They show several possible layouts, with rows of photodetectors positioned between LEDs across the width of the sensing area. Some versions use four detectors, while others expand that to six. 

Effectively, Oura wants several slightly different views of the same pulse. Comparing when those signals arrive, and how they differ, could provide information that a single detector cannot.

Blood pressure is not just a throwaway reference

Patents often contain enormous lists of measurements that a device might theoretically support, so a mention of blood pressure on its own would not tell us much. This filing goes considerably further because blood pressure and other vascular measurements appear directly in the patent claims.

That also makes this filing different from the blood pressure work we covered earlier this year. That previous Oura patent concentrated heavily on pulse timing, synchronisation and calibration. This one looks more like an attempt to improve the raw signal itself by changing the optical hardware inside the ring. 

The two approaches could ultimately complement each other. Better optical measurements give the software cleaner data to work with, while the processing system then has to turn those signals into something useful.

Oura also says readings from several photodetectors could simply be averaged to improve the accuracy of ordinary physiological measurements. So even if blood pressure never becomes a consumer feature, the same arrangement could potentially improve existing PPG-based tracking. 

There is more hiding in the filing

The patent goes beyond optical sensing. Oura also describes inner and outer electrodes that could create an electrical path through the wearer when they touch the outside of the ring with a finger from the opposite hand.

That arrangement could potentially support ECG, bioimpedance and electrodermal activity measurements. Oura says bioimpedance could provide information related to muscle mass, body fat or hydration, while EDA could be used for things such as galvanic skin response and stress-related measurements. 

There is even a reference to NFC for payments, authentication and unlocking external devices. Those ideas sit further away from the core invention, though, so we would not read them as evidence that Oura is preparing an NFC ring.

Still, the direction is pretty clear. Oura is looking at ways of getting much richer vascular information from the finger, and this particular filing shows that the company is attacking the problem at the sensor level rather than relying entirely on software.

The post Oura patent points to blood pressure and arterial stiffness tracking appeared first on Gadgets & Wearables.

One of the first owners to post detailed impressions said setup was straightforward and that they were quickly using Index 01 to create shopping lists and reminders. More impressively, voice recognition apparently worked well in a noisy train station, which is a useful real-world test for a device built almost entirely around spoken input.

That lines up with what Pebble has claimed from the start. Index 01 is designed to be held close to the mouth, allowing the microphone to focus on nearby speech rather than the wider environment.

The core idea seems to work

Other early reports are positive too. One Android owner said the hardware and software worked smoothly, with commands interpreted quickly and accurately. They had already connected Index 01 to their own server through webhooks and started experimenting with custom actions.

An iPhone user also managed to create reminders through Apple Reminders and Google Tasks once Bluetooth permissions were enabled for the Pebble app.

That flexibility was one of the more interesting parts when Pebble first announced Index 01. The hardware is deliberately simple. Most of the useful stuff happens through the app, where recordings can become notes, reminders and other actions.

There are already a few rough edges, though. One owner found Android music controls noticeably slow, with around four seconds between a double tap and the requested action.

Software is the weak point for now

Several Android users have run into more serious problems. In the growing thread of early owner experiences, some managed to pair the ring but found that recordings were not appearing in the Index feed. One owner fixed an initial pairing issue with a factory reset, only to find that recordings still would not transfer.

Another user reported that onboarding never appeared properly after pairing. That is more annoying on Index 01 than it would be on most wearables because the battery cannot be recharged. Troubleshooting is not going to destroy the battery overnight, but every test still uses part of a finite resource.

Pebble has already warned buyers to expect early software bugs, so none of this is especially surprising. The first production units are effectively showing where the weak spots are.

Sizing may also be inconsistent. One early owner found the production ring much tighter than expected and was glad they had moved up a size. But another owner reported the opposite, saying their production ring felt slightly larger than the sizing model they had used.

That makes it hard to say Index 01 simply runs small. Pebble has advised buyers to size up when uncertain, and these first deliveries suggest that advice is worth taking seriously.

It is still far too early for a verdict. Only a small number of production units are in the wild, and people with problems are naturally more likely to post about them.

Still, the first owner reports answer one useful question. Index 01 does not appear to fall apart once it leaves the demo environment. Voice capture can work well, the integrations look genuinely useful and the open approach gives the ring plenty of room to grow.

For now, the hardware concept looks more convincing than the software supporting it.

US patent application 2026/0219706 A1 was published on July 30. This does not confirm that an Amazfit Helio Ring 2 is around the corner, but it gives us a useful look at the ideas Huami has explored for its smart ring platform.

The patent claims priority from an earlier Chinese filing made in October 2023. That means the underlying work began before the first Helio Ring reached the market, and several parts of the design overlap with the current model.

Those include optical heart rate and blood oxygen tracking, skin temperature measurement and electrodermal activity. In our Amazfit Helio Ring review, I found the first-generation device particularly strong during exercise, an area where many smart rings still struggle.

The more interesting parts of the patent describe features that the current ring does not offer. This includes body composition measurements and ECG recording.

One pair of electrodes could do several jobs

The proposed ring has two large, curved electrodes running around most of its inner surface. Together, they can cover more than two-thirds of the ring’s internal circumference, giving them a larger contact area with the finger.

Huami says these electrodes could collect electrodermal activity, body impedance, ECG and temperature signals. They could also act as charging contacts when the ring is placed inside its case.

Using the same electrodes for several functions would reduce the need for separate contacts and free up space inside the ring. The patent describes switching circuitry that changes how the electrodes connect depending on whether the ring is collecting health data or charging.

The drawings also show a curved battery and circuit board occupying separate sections around the ring. Huami says this arrangement can use the available space more efficiently and reduce the thickness of the device.

A charging case would be another useful change. The original Helio Ring uses a small dock, which worked reliably during our testing but could be fiddly when aligning the ring.

Body composition looks like the strongest upgrade

Body composition is one of the potential new features. The patent describes using bioelectrical impedance analysis to estimate measurements such as body fat.

A basic version could use the two electrodes inside the ring. A more advanced setup could add conductive areas to the outside, allowing the wearer to touch the ring with another finger and create a longer electrical path through the body.

Huami also describes combining the ring with another wearable. One example uses an electrode on a smartwatch as an additional contact point, allowing the watch and ring to perform a multi-electrode body composition measurement together.

ECG and improved optical tracking are also possible

The electrodes could also capture ECG signals. The patent does not describe a finished ECG feature or explain how the wearer would complete a reading, but an outer contact could let someone touch the ring with their opposite hand in much the same way as a smartwatch ECG.

Huami also explores more elaborate optical sensor layouts. These can include multiple light emitters and detectors, convex lenses and several optical paths with different distances between components.

Using several paths could help the ring find a cleaner signal when its position changes or when the fit is less than perfect. It could improve heart rate, blood oxygen and movement performance without relying solely on tighter contact with the finger.

The patent briefly mentions blood pressure and glucose among the measurements an optical sensor might support. However, it provides no detailed method for either feature, so those references are too broad to treat as evidence of a glucose or blood pressure ring.

There is no guarantee that all this will appear in a second-generation Helio Ring. Still, the document shows where Huami sees room to expand. A future model could be slimmer, easier to charge and capable of body composition or ECG.

That would give the Helio line a clearer identity in an increasingly crowded category. The first model already holds its own among the best smart rings available today, but these extra features might make the next version stand out more.

The post Next Amazfit Helio Ring could add body composition and ECG appeared first on Gadgets & Wearables.

The update starts rolling out globally today and is free for existing users. It applies across Ultrahuman’s wider ecosystem, including the Ring AIR and Ring PRO, the M1 and M2 Live glucose monitoring services, Blood Vision and the Ultrahuman Home.

The app now focuses on what to do next

UltraSphere sits at the centre of the redesigned home screen. It turns health data into more than 60 suggested actions based on sleep, recovery, HRV, movement, stress, skin temperature, cycle phase and glucose readings.

These can include getting outside for morning light, taking a short walk during an afternoon energy dip, cutting off caffeine or beginning an evening wind-down routine. The recommendations can also adjust for location, weather, circadian timing and different routines, including shift work, parenthood and frequent travel.

The company’s Jade AI health assistant now gets its own tab. It connects information from across Ultrahuman’s devices and services rather than treating ring, glucose and blood test data as separate streams.

The redesign also moves longer-term measurements such as UltraAge, Pulse Age, Blood Age and Brain Age into a dedicated Longevity tab. Meanwhile, the new Windows view places time-sensitive information, including caffeine timing and circadian phases, onto a single daily timeline.

More insights now work offline

Emerald moves more analysis onto the phone, allowing sleep, recovery and movement scores to calculate without an internet connection. Live heart rate, stress, steps and UltraSphere recommendations can also remain available while offline.

This should be useful during flights, travel and time spent in areas with poor reception. It also means more of the app remains functional without a continuous connection to Ultrahuman’s servers.

Sleep Screener brings sleep duration, temperature, respiratory information, rhythm data and the Ultrahuman Smart Alarm into one nightly view. AFib Detection, where supported, also sits here after previously launching through Ultrahuman’s PowerPlugs platform.

Workout tracking gets an upgrade

Ultrahuman says it has also rebuilt workout tracking for Ring AIR and Ring PRO, with improved automatic detection, activity tagging and heart rate algorithms. This is an area worth watching, as workout heart rate was one of the weaker points in my Ultrahuman Ring AIR review.

The VO₂ Max algorithm has also been revised. Ultrahuman says it tested the estimate against CPET laboratory results from more than 100 athletes, with readings falling within 5 mL/kg/min of the lab measurement.

Emerald’s main change is a cleaner way of presenting Ultrahuman’s existing data and services. The redesigned interface and offline processing should make the app easier to use, while the new heart rate and VO₂ Max claims will need testing once the update reaches more users.

Users want the missing features saved

Oura quietly added a discontinuation notice to its support pages in June, saying Oura on the Web would close later this year. The company did not initially provide a date, although an official Oura representative has since told users on Reddit that the dashboard will remain available until September.

The announcement has now started generating more pushback. On social media, some users are encouraging others to contact Oura and explain which parts of the dashboard they want preserved.

Oura on the Web lets members place two metrics on the same graph, adjust the period being examined and see a correlation value showing how closely the data points move together. Someone could compare activity with REM sleep, for example, or look at whether one day’s activity appears to influence HRV the following night.

Oura itself describes the dashboard as a tool for exploring long-term health patterns and comparing personal metrics. Its mobile app includes trends and tags, but it does not currently offer the same flexible correlation view found on the website.

Data access is another concern

Another issue is exporting data. At the moment, Oura on the Web lets users select metrics and download them directly as a CSV file, making it relatively easy to analyse the information elsewhere.

Once the dashboard closes, users will still be able to request an export through the Oura Membership Hub. That option is available with or without an active membership, but Oura warns that the download may take up to 10 days to arrive.

The Oura API will also remain available, which gives developers and technically minded members another route to their data. Still, an API is not a direct replacement for a ready-made dashboard that anyone can open in a browser.

Oura has spent much of this year adding more information and health features to its software. The company launched a sizeable feature bundle with Oura Ring 5 and later brought many of those additions to older Oura rings. Removing a mature analysis tool at the same time feels like a step in the opposite direction.

Oura has heard the complaints

The Reddit user shared a screenshot of their conversation with Oura support. The representative acknowledged that the web dashboard provides an alternative way to access data without opening the app and said the feedback would be passed to the appropriate team.

That does not mean Oura is reconsidering the closure. For now, the company still plans to retire the dashboard and says it will publish more information before that happens.

The post Oura users push back as web dashboard heads for shutdown appeared first on Gadgets & Wearables.

A bigger second attempt

Ring One 2.0 builds on the same basic idea as its predecessor. Muse wants to make a smart ring that does more than monitor sleep, activity and recovery.

According to the company’s Ring One 2.0 launch page, the new model will track sleep, exercise, mindfulness and general wellness while adding cuffless blood-pressure readings, AFib detection, sleep-apnea detection and vascular-health insights. Muse also claims six to seven days of battery life, with the charging case extending total use to around one month.

The company is placing greater emphasis on software this time. New AI applets are there to target specific goals such as sleep, recovery, fasting, metabolic health, weight management and mental wellbeing.

Muse is also keeping Ring One’s wider digital ambitions. Ring One 2.0 is being promoted as a contactless payment device, a key for compatible Tesla vehicles and smart doors, and a tool for passwordless authentication. There will be no mandatory subscription.

It is an impressive list. The question is how much of it will work at launch, where each feature will be available and whether health functions such as AFib and sleep-apnea detection will carry the necessary regulatory clearances in different markets.

The first Ring One took a difficult route

Let’s look back.

Muse launched the original Ring One campaign on Indiegogo in late 2023. It raised close to $1.7 million from more than 7,500 backers, helped by a feature list that included blood-pressure readings, contactless payments, haptic feedback and a rotating outer control.

Delivery was initially expected a few months later. Instead, the campaign slipped through a long series of revised production and shipping schedules, with many international backers waiting well into 2025 before receiving anything.

As we reported when Ring One began shipping internationally, the finished device also differed from the original pitch. There were no blood pressure readings, rotating control disappeared, payments were not ready for most owners and several software features remained under development.

Muse later activated on-demand blood-pressure readings. Even so, availability is not the same as validation. The company has not yet published enough independent evidence to establish how closely its cuffless blood-pressure estimates compare with a validated upper-arm monitor across a broad population.

Current owners are not uniformly happy

The response on social media to the Ring One 2.0 announcement has been noticeably sceptical. Recent comments include original backers asking about undelivered orders, outstanding refunds and replacements for failed first-generation hardware.

Charging cases appear to be a recurring source of frustration. Several owners say their cases stopped charging the ring after a relatively short period, while others report waiting months for redesigned replacements. There are also complaints about overheating, cracked internal resin, pairing failures and inconsistent syncing.

Payments remain another weak spot. Muse has introduced payment support in some markets, but recent owner discussions suggest that card enrolment and transaction support still vary considerably by country and provider.

Of course, not every report is negative. Some owners say they like the ring’s sleep data and general health tracking. And in fairness, Muse has also continued issuing app and firmware updates rather than abandoning the original device.

Muse still has something to prove

Ring One 2.0 could fix some of the original model’s biggest weaknesses. Muse says it has improved the design, with better build quality, a redesigned charging case and more polished software all on the list.

But after everything that happened with the first Ring One, it is worth keeping the usual crowdfunding caveats in mind. Backing an Indiegogo campaign is not the same as buying a finished product from a shop. Shipping can slip, features can change and your money is at risk if the project does not deliver.

Muse has already opened a reservation page offering early supporters discounts of up to 50%. Final pricing, delivery estimates and the full specifications are still under wraps, so we should know a lot more when the campaign goes live on August 4.

The post Muse returns to Indiegogo with the more ambitious Ring One 2.0 appeared first on Gadgets & Wearables.

The patent application, titled “Techniques for evaluating ambient light exposure and chronotype via wearable devices,” was published on July 16. It combines ambient light readings with sleep data, physiological measurements and a person’s chronotype, rather than treating light as another isolated metric. 

The ring could reuse its existing optical sensors

So how would Oura collect this data? The patent says a ring could use the same light-receiving components already involved in physiological measurements, although a separate ambient light sensor is also covered.

In one example, the ring takes a normal health reading while its LEDs are active, then measures environmental light while those LEDs are switched off. That would allow the photodetectors to pick up light from the room or outdoors without requiring a large new sensor on the outside of the ring.

This is entirely possible as RingConn already has a similar feature. That device uses its built-in PPG optical sensors not just for heart rate, but also to detect ambient light levels. This allows it to measure the intensity of environmental lighting throughout the day.

Oura wants to take this further. The filing covers the timing, intensity, duration and colour of the light reaching the wearer, including ultraviolet exposure and different parts of the visible spectrum. It could then compare those patterns with sleep timing, recovery and the wearer’s usual body clock.

Oura could then change the room

The more unusual part of the patent is what happens next. Oura describes a system that could communicate with connected lights, curtains, blinds and shades around the wearer.

The setup could dim bedroom lighting as bedtime approaches, close blinds when evening light is likely to interfere with sleep or open them in the morning. Some actions could happen automatically, while others might appear as suggestions inside the Oura app.

Users could also create simple rules. A light might switch off once the ring detects that the wearer has fallen asleep, or blinds could open when they remain asleep beyond a chosen time.

This does not mean Oura is about to launch a smart home platform. It does show the company thinking beyond the ring itself and looking at how the surrounding environment might affect the data it already collects.

Light could become another recovery input

The patent also suggests using ambient light to help explain changes in Oura’s scores. If sleep timing, heart rate variability or recovery suddenly shifts, the app could recognise unusual light exposure as a possible reason rather than treating the change entirely as a physiological problem.

Oura also covers UV exposure, skin-related insights and estimates linked to vitamin D production. Those ideas look less straightforward because a ring cannot know exactly how much light reached the eyes or how much skin was exposed, but the filing allows data from location, weather and other sensors to fill in some of the gaps.

There is no guarantee any of this will appear in a future Oura Ring. Patent applications often cover broad ideas that never make it into a product, but this one fits Oura’s current direction unusually well.
