Wearable health tech is stepping beyond the usual wristbands and smartwatches. A new wave of devices blends style with serious health tracking. This includes smart necklaces, rings, and bracelets designed to fit seamlessly into everyday life.

One eye-catching innovation comes from a former Fitbit executive. The company, called The90, launched a smart necklace named The Gem. It tracks real-time UV exposure using sensors that detect UVA and UVB rays. This helps users monitor how much sun they get, whether they’re outside or sitting near a sunny window.

The necklace sends data to an app that builds a personalized skin profile. It offers advice on sunscreen use, safe sunlight windows, and personal UV limits. The Gem is a pendant, setting it apart from typical UV sensors you wear on your wrist. It costs $300, with an early-bird price of $200 available for a limited time.

Health Tracking Meets Fashion in Smart Jewelry

Meanwhile, another company named Inllie released the Luna Light bracelet. It’s designed with women in mind, featuring moissanite stones in gold or silver-plated styles. At just 11 grams and 5.6 millimeters thick, it’s ultra-light and comfortable.

Beyond looks, the Luna Light tracks heart rate, blood oxygen, sleep, stress, and more. It also supports women’s health features like menstrual, ovulation, and pregnancy tracking. All information is viewable through a companion app. The bracelet launched at $109 but is currently discounted to $69 for a limited time.

These smart jewelry pieces show how wearable gadgets are blending health monitoring with fashion. They no longer feel like gadgets but more like accessories you’d want to wear daily.

Small Chips Bring Lab-Grade Health Monitoring to Wearables

On the tech side, researchers at the University of Cambridge and startup GlitterinTech created a tiny $10 spectrometer chip. This chip brings powerful chemical sensing to wearables without the bulk or high cost of traditional lab equipment.

The chip doesn’t split light like old spectrometers. Instead, it uses a math operation called convolution to analyze light. This allows it to accurately identify materials and measure chemicals in real time. It can even track health markers like skin moisture, blood alcohol, lactate, and glucose levels.

Tracking blood glucose non-invasively could be a game-changer for people with diabetes. The chip works fast and stays accurate across extreme temperatures. It needs little computing power, making it easy to add to smartwatches or rings.

This chip could turn everyday wearables into advanced health monitors. Imagine your watch or ring giving lab-quality readings without needles or bulky gear.

Other wearable devices continue to push boundaries too. For example, the new Oura Ring 5 shrinks its size by 40% while adding blood pressure and nighttime breathing tracking. It also supports live workout tracking and improved data privacy controls. The ring can last up to seven days on a charge, making it a serious contender in smart ring tech.

Fashion brands are joining the smart health trend as well. Kate Spade launched hybrid watches and fitness trackers that combine style with basic health features. These devices sync with phones, track sleep and activity, and offer notifications without needing constant charging.

All these innovations show health tech is moving toward devices that fit naturally into daily life. Instead of bulky gadgets, we’re getting smart jewelry and tiny chips that blend style and science. It’s a future where health tracking is as simple as wearing your favorite necklace or ring.
