Smart Ring Materials And Sensors

Ceramic, enamel and antibacterial stainless steel, and what each sensor actually reports

Three Material Routes, Three Price Positions

Shell material	Published weight	Character
Microcrystalline zirconium nano-ceramic with antibacterial stainless steel inner ring	about 5 g	Hardest surface, most resistant to scratching
Austenitic antibacterial stainless steel with transparent epoxy resin	about 6 g	Robust, familiar metal finish
Antibacterial stainless steel shell with transparent oxidised resin inner shell	3.8 g	Lightest metal build in the range
Enamel, carved and filled with oil paints over multiple processes	3.8 g	Decorative, closest to jewellery
Ceramic surface, NFC access control model	3.8 g, 7 mm thick	Wear and scratch resistant, thinnest profile

Why Weight Matters More Than It Sounds

A ring is worn continuously or it is worn never. Sleep data, overnight heart rate and 24 hour activity all depend on the wearer not taking it off, and the difference between 3.8 g and a heavier build is the difference between a habit and a drawer.

The Sensor Stack

Our rings combine photoelectric sensors, an accelerometer, an optical heart rate sensor and an optical blood oxygen sensor, running simultaneously. The accelerometer handles movement, step counting and sport modes. The optical sensors sit against the underside of the finger, where the tissue is thin and the signal is cleaner than at the wrist.

What Each Model Reports

Sleep monitoring on every published model
24 hour and real-time heart rate monitoring
Real-time blood oxygen monitoring
Blood pressure monitoring on several models
Daily activity and 24 hour exercise data monitoring
Multiple sport modes recording heart rate, speed and time
Remote photo capture by shaking the ring through the app

Sealing And Charging

Every published model is IP68 waterproof and dustproof, which is what allows the ring to stay on through hand washing. Charging is magnetic, with capacities from 18 mAh to 23 mAh; the ceramic model includes a charging case with its own 400 mAh battery, and a charging case is offered as an option on the enamel model.

A Note On Health Claims

These are consumer wellness products. Sensor outputs are for general fitness and lifestyle tracking, and marketing copy in your destination market should be reviewed against local rules on medical claims before launch.
