Motorola’s Patent Isn’t a Phone You Wear, It’s a Watch You Unfold

Posted on by

The idea of merging a smartwatch and a smartphone into a single device has been floating around the industry for years, mostly because the obvious inconvenience is right there: two screens on two separate devices, one tiny and worn on the wrist, the other large and kept in a pocket, each doing essentially half the job the other can’t. The logical question is whether one of those devices could do both jobs depending on the situation.

Motorola’s latest patent, officially registered as US12,693,705 under the title “Pivoting wearable reconfigurable screen,” proposes exactly that. The device starts on the wrist as a conventional smartwatch, its flexible display curved around the band. When more screen real estate is needed, the strap pivots and unfolds, flattening into a short, wide display format that functions as a handheld device. A third configuration folds the bottom quarter into an “L” shape, turning the unit into a self-standing desk display.

The mechanism that makes it possible is the strap itself. Rather than housing a traditional watch face with a fixed display, almost the entire outer surface of the band carries a flexible screen. Worn, it reads like a standard wearable. Removed and unfolded, that same surface becomes the display area of a compact, landscape-oriented device. The pivot point is what separates this from simply being a wrist-wrap phone like earlier concepts.

That distinction matters because Nubia tried the wrist-phone idea back in 2018 with the Alpha, and the result was a fascinating but limited object. The Alpha wrapped a 4.01-inch OLED display around the upper wrist, delivering more screen real estate than any smartwatch before it, but the display stayed wrapped. It curved beautifully, could make calls, take photos, and run apps, but it never transformed into anything. The watch was the watch, full stop.

Motorola’s patent reverses the logic. Rather than making a phone you can wear, it proposes a watch you can unfold. The distinction isn’t purely semantic. A device that starts as a watch and transforms into a handheld is solving a different problem than one that starts as a phone and straps to your wrist. The first carries a reasonable identity in both states; the second always feels like a compromise in one of them.

The Nubia Alpha’s sticking point wasn’t the display, which was genuinely impressive and ahead of its time. It was the software, the battery, and the form factor’s limits in practice. Nubia never took the concept further after the original and a 2020 follow-up. The flexible display remained horizontal and wrist-bound, never taking the step toward becoming a genuinely detachable, self-sufficient screen.

Whether Motorola’s patented concept eventually ships as a real device is a separate question entirely. Patents are filed routinely without becoming products, and this one would require flexible display technology durable enough to handle daily wrist bending and regular unfolding, a battery that fits within strap dimensions, and software that transitions cleanly between modes. None of those are trivial problems.

Still, the direction of thinking has clearly shifted since 2018. Nubia asked what happens when a smartphone lives on your wrist. Motorola is asking what happens when a watch becomes a screen the moment you need one.

Smart Rings Finally Got a Reason to Exist Beyond Sleep Tracking

Posted on by

The smart ring market has had a good run on heart rate and sleep tracking. Oura, Samsung Galaxy Ring, and their growing circle of competitors have made it genuinely useful to wear a small device on your finger all day. But if you’ve been waiting for wearable health tech to go deeper than pulse and REM cycles, engineers at UC San Diego may have just drawn the roadmap.

Their prototype, called CHARM (Continuous Health Analyzing Ring Module), doesn’t check your heart. It reads your sweat. Specifically, the microscopic amount of sweat that your fingers naturally produce throughout the day, no gym session required. Through a built-in osmotic hydrogel that draws moisture out passively, the ring collects and analyzes up to four chemical biomarkers at a time: glucose, ketones, vitamin C, uric acid, lactate, and alcohol. It then sends that data wirelessly to a smartphone.

Designer: UC San Diego engineers

That list of biomarkers is worth sitting with for a moment. Glucose and ketones tell you about your metabolic state and how your body is processing energy. Lactate relates to physical exertion and muscle activity. Uric acid is linked to inflammation and conditions like gout. Vitamin C reflects dietary intake. Alcohol levels speak for themselves. Getting any one of these readings from a non-invasive wearable is already impressive. Getting all of them simultaneously, continuously, and without drawing a single drop of blood, is something else entirely.

The research, published in Nature Communications and led by postdoctoral researcher Tamoghna Saha in the lab of Joseph Wang at UC San Diego, has already passed some important early tests. In trials with participants both with and without Type 1 diabetes, CHARM’s sweat-based glucose readings closely matched results from a standard continuous glucose monitor. Its ketone data similarly aligned with readings from a traditional blood meter. For a prototype, that’s a meaningful validation and a strong signal that the underlying science holds up outside of a lab setting.

What makes this feel like a genuine step forward, rather than just another research headline, is how clearly it names the gap in current wearable technology. As Saha put it, commercial rings only provide biophysical information but lack the molecular data that offers deeper insights into an individual’s health. That is a polite way of saying that knowing your resting heart rate is useful, but it doesn’t tell you whether you’re running low on vitamin C or how your body actually responded to what you ate for lunch.

The design challenge here is real, and I think it deserves more credit than the flashier headline about sweat gets it. Cramming accurate chemical sensors, a hydrogel layer, data processing, and wireless connectivity into a ring-shaped form factor is not a small engineering problem. The current prototype, which clamps around a finger, is still a long way from the slim, polished bands we’ve grown used to slipping on without thinking. Getting it there, while keeping the sensor accuracy intact and the battery life practical, will be the hard part. But that is exactly the kind of design and miniaturization problem that tends to get solved once the underlying science is proven. The history of consumer health tech is basically a series of “we figured out the science, now let’s make it wearable” moments.

The smart ring category has felt a little flat lately, if I’m being direct. The differences between most devices come down to software features and companion app design, not any fundamental leap in what they can actually detect. CHARM points toward a version of the smart ring that is genuinely measuring your body’s chemistry in real time, the kind of data that has historically required a clinic visit or a prescription-grade device. Putting that on a finger, passively, all day, changes what personal health monitoring can realistically mean.

It’s still early. CHARM is a prototype, the paper is fresh, and a consumer version is nowhere near announced. But the direction is right, and the science backs it up. If biochemical monitoring eventually becomes a standard feature of smart rings rather than a research novelty, this prototype will be one of the moments worth pointing back to.

A Designer Just Answered Facial Recognition With a Medieval Visor

Posted on by

Facial recognition has become one of the fastest-growing forms of infrastructure in public life. Cameras in airports, transit systems, retail spaces, and city streets capture biometric data routinely, often without the awareness of the people being scanned. The face has gradually become something closer to a credential, an identifier read by systems that process it instantly against databases that are constantly growing.

OBEX is a conceptual wearable that treats this shift as a design problem worth addressing through physical form. Rather than responding to surveillance with software or policy, it proposes a new category called “privacy armor,” a tangible boundary between the wearer and systems of biometric recognition. Its form language doesn’t come from consumer electronics but from something much older, the medieval visor.

Designer: Haechan Ryu

In medieval warfare, a knight’s visor concealed identity while creating distance between the person and the world beyond the armor. The logic behind OBEX borrows that idea and applies it to a different kind of threat, one that’s less physical and more informational. As surveillance systems continuously collect and analyze biometric data, the face becomes a vulnerable interface, and OBEX imagines what it would mean to shield it.

The visor itself is made from a micro-perforated optical film that allows the wearer to see out clearly while appearing opaque from the outside. It’s a deliberate asymmetry, the kind that surveillance systems rely on, reversed and put in the hands of the individual. The shielding motion references the sliding visors of historical armor, and the weight distribution is engineered to reduce strain across the head during long wear.

The temple module anchors the visor to the head and holds most of the active technology. Embedded PPG sensors monitor physiological data in real time, enabling continuous biometric monitoring through the wearer’s own biological signature. Dual directional speakers deliver audio feedback without cutting the wearer off from surrounding sounds, and a small bitmap display on the side communicates system status and shield activation modes at a glance.

The frame is precision-engineered titanium, chosen for its balance of strength and low weight. The outer surface carries a refined micro-texture that improves grip while minimizing visible wear over time. The ornamental detailing on the temple module draws from the craftsmanship traditions of medieval armor, with intricate surface patterns that make the component read more as a personal artifact than as a piece of hardware.

OBEX isn’t proposing that everyone should walk around in a visor. It’s asking what protection means when the thing being protected isn’t the body but the face’s function as an identity signal. The concept sits at the edge of speculative design and industrial practice, using grounded materials and structural logic to imagine an object that doesn’t quite exist yet, but one that feels increasingly necessary.

Rogbid SpinR is a rugged, budget-friendly smartwatch with optical scroll wheel for navigation

Posted on by

Rogbid believes traditional crowns are so dead. The watches now need mouse-style scroll wheels because, why not? If you think that’s a good idea, and want to give yourself a head start on the design idea without committing too much on the price front, check out the Rogbid SpinR – a budget-friendly smartwatch with rugged features and an optical scroll wheel for navigation.

SpinR is an entry-level smartwatch. Rogbid has priced it at a very affordable $49.99. But what you get for the price – minus onboard GPS – is pretty noteworthy. First up, you have the metal case of the watch, which is made from zinc alloy and features a vacuum-plated finish. Offered in two colors – black and orange- the watch feels quite premium on the wrist. Despite the price and material usage, it’s not one of those chunky watches. It’s smart enough to go from work to gym, and anywhere else your adventure may take you.

Designer: Rogbid

The case, however, is not small in any way. It measures 51 mm diagonally and is 13.4 mm at the thickest point. As noted, the main highlight of the SpinR is not its case. It’s that optical scroller built into the side crown. A jewel on the large case, the optical scroll wheel functions somewhat like the crown on the Apple Watch – for navigation. You can navigate the menu, adjust settings, and control apps with the scroll wheel without touching the screen at any time. This can be particularly helpful when you have sweaty hands or your fingers are covered in chip crumbs.

According to the company, to simplify the interactions, the scroll wheel uses light to register scrolling movement when you are changing the volume, scrolling through your music library, or increasing the flashlight intensity. The process of the wheel’s functioning is pretty similar to that found in gaming mice.

Besides the innovative wheel for navigation, the Rogbid SpinR smartwatch wears a 1.7-inch display. It is unclear whether its LCD or AMOLED panel, but what we do know for certain is that it features a 360 x 360-pixel resolution. The watch draws power from a 7074 A7 chipset with 128 MB of flash storage and comes with some standard smartwatch features such as heart rate tracking and a pedometer. What the SpinR misses is built-in GPS. For precise location tracking, therefore, the watch featuring Bluetooth 5.4 will rely on the paired phone.

You want the smartwatch you own to work for a few days without requiring a recharge. The Rogbid SpinR could be one such offering with its 1100 mAh battery, which the company claims has 100-plus days of standby time. In real-world usage, of course, it’s going to be way less, but with the magnetic charging, it will give you a quick way to refuel if you’re caught up running out of power on the go. SpinR has a plastic caseback and comes paired with a silicone strap. The watch is rated IPX8 and features 30-meter water resistance.
