Galaxy Watch Sniffs Your Diet: A Carotenoid-Based Antioxidant Score in 5 Seconds

Samsung's Galaxy Watch features an Antioxidant Index that estimates your antioxidant level by measuring carotenoids in the skin using the BioActive sensor. By placing a thumb on the back LEDs, the watch analyzes blue-light absorption and returns a 0–100 score, categorized as Very low, Low, or Optimal, and viewable in the Samsung Health app. While it provides a quick snapshot of diet-related antioxidant status and can track trends, it doesn't capture all antioxidants in the body and can be influenced by factors like activity, sleep, stress, UV exposure, and diet; meaningful changes may take weeks to register.

French smart bra uses AI to flag early breast cancer signs

A French-Swiss research team developed the PHI-BRA smart bra, a 30-minute wearable that combines skin-surface thermography and electrical impedance spectroscopy, analyzed by AI, to screen for early signs of breast cancer. While not a replacement for mammograms, it could provide an accessible screening option between medical visits as clinical trials continue and researchers look to scale the technology.

Galaxy Watch9 Turns Health Data Into Real-Time Guidance

A New York Post review of the Samsung Galaxy Watch9 highlights its health-focused features—real-time heart-rate tracking, vibration nudges for movement, and the Fitness Index that compares users’ fitness to peers—along with sleep coaching, body composition scans, Vitals metrics, ECG and blood pressure. It emphasizes the watch’s AI-assisted insights and goal-driven workouts, while noting these metrics are informational and work best with Galaxy/Android devices.

Ultrasound Wearable Accelerates REM Sleep Without Drugs

UT Austin researchers developed a soft wearable patch (NEUSLeeP) that uses ultrasound and real-time brain monitoring to noninvasively target REM sleep, making users enter REM 43 minutes faster and stay about 16 minutes longer in a 28-person study, with evidence of improved heart-rate variability and changes in emotion-related brain circuits, hinting at benefits for stress and mood regulation and potential applications for PTSD, depression, and insomnia; larger trials and commercialization are planned.

Sony's neck-worn wearable air conditioner chills only a patch of skin, not the room

Sony's neck-worn wearable air conditioner chills only a patch of skin, not the room

Sony's Reon Pocket Pro Plus uses a Peltier cooling module placed at the base of the neck to create a cool sensation; it cools only a small patch of skin, not the surrounding air, and whole-body comfort is more influenced by facial cooling in studies. Sony claims about 2°C better performance over prior models in lab tests; availability remains Japan-first with uncertain U.S. release.

Casio debuts full-metal smart ring for health tracking

Casio unveils its first smart ring, the CRW-H001, a full-metal wearable that combines digital timekeeping with health tracking (steps, calories, heart rate, SpO2, body temperature, sleep, recovery) and discreet smartphone notifications via vibration. Built with metal injection molding for a one-piece ring, it pairs with a Casio app on iOS, Android, and select HarmonyOS devices; available in sizes 9–11 and sold exclusively in China with limited after-sales service, signaling Casio’s shift from novelty ring watches to practical wearables.

Ring that reads glucose from sweat could spare diabetics from finger-pricks

Ring that reads glucose from sweat could spare diabetics from finger-pricks

UCSD researchers have developed a prototype smart ring that uses an osmotic hydrogel to pull sweat and electrochemical sensors to measure glucose and other biomarkers. In tests, the ring’s glucose readings closely matched commercial CGMs and ketone readings matched blood meters, suggesting a noninvasive alternative to finger-pricks. The device still needs extensive validation, has a 12-hour battery life, and remains bulky in prototype form, but could benefit diabetics, athletes, and other health monitoring applications.

Step-count showdown: Fitbit Air edges Garmin Cirqa in early test

Tom’s Guide pits the Garmin Cirqa against the Fitbit Air in a hands-on, screenless-tracker face-off. Both devices count steps via an accelerometer, but the Fitbit Air comes closest to a manual 5,500-step tally (about 5,552 steps) while the Garmin Cirqa records 4,605 steps and, crucially, failed to register the walk as a walk in Garmin Connect. Garmin notes the Cirqa gets smarter with more use. Overall, the Fitbit Air wins this step-count test, though Cirqa remains competitive thanks to its long battery life and ongoing software improvements.

US Debut of Hilo Core Turns Blood Pressure Monitoring Into a Daily Wearable Companion

US Debut of Hilo Core Turns Blood Pressure Monitoring Into a Daily Wearable Companion

Aktiia's Hilo Core system, now available in the US, combines an FDA-cleared blood pressure cuff with a slim wristband to continuously monitor BP and provide long‑term insights. After a four‑day calibration, cuff readings establish a baseline and are performed monthly, while the band auto‑reads BP about every 90 minutes (up to 35 readings per day) using optical sensors. The kit costs $90, plus a $150 annual subscription; in Europe it has shown BP reductions. The wristband is currently a wellness device (not FDA‑cleared), and readings are meant to supplement medical advice, not replace it. Privacy notes say data is anonymized and not sold to third parties.

Ink-on-skin tattoo reads ECG and drives a robotic hand

Ink-on-skin tattoo reads ECG and drives a robotic hand

Penn State researchers created a washable, paint-on electronic tattoo using conductive ink that dries on the skin to form an electrode for ECG/EMG/EEG signals. The tattoo connects to a Bluetooth module via a porous silver textile and can control a robotic hand in tests. It can be customized with colors and is designed to stay attached during movement, offering a more comfortable alternative to traditional patches. Future work could include monitoring biomarkers like glucose or cortisol and even plant health, but the technology is not yet ready for consumer use or clinical diagnosis, and it has not been tested on heart-attack patients.

When a wearable spotted pregnancy before she did

BBC profiles Ravika, who was alerted by her Oura ring to a poor health score, elevated temperature and lower HRV before she could confirm pregnancy, a pattern some users report across wearables. While such devices can hint at early pregnancy through temperature and other metrics, experts warn the data isn’t reliable enough for medical decisions and can cause anxiety; doctors advise using wearables as a supplement to care, not a replacement, and note rising use as wearables become more common in the UK.

Paintable Skin Electrodes Signal a New Era for Wearable Biometric Monitoring

Researchers from Penn State, MIT, and China developed WE-PPD, a safe, paintable polymer electrode that can be painted directly onto the skin to monitor heart rate, muscle activity, and brain waves. In tests, the electrode maintained about 95% ECG consistency before/after mild sweating and surpassed traditional films in breathability, while remaining flexible (stretching up to ~170%). It could enable tattoo-like, customizable biointerfaces and extended pediatric monitoring, though more safety evaluations—especially MRI compatibility—are needed before clinical use.
