Ultrahuman Ring AIR: Features, ratings, prices and more

The Ultrahuman Ring Air is a next‑generation smart ring designed for comprehensive health and fitness tracking. Crafted from fighter jet grade titanium with a Tungsten Carbide Carbon coating on the exterior and a medical‑grade hypoallergenic epoxy resin on the interior, it promises durability while remaining comfortable for continuous wear. The ring is round in shape and engineered for precision with multiple advanced sensors—including infrared photoplethysmography, non‑contact skin temperature measurement, 6‑axis motion tracking, and LED-based heart rate and oxygen saturation monitoring. It runs on a rechargeable 24 mAh LiPo battery that can power the device for up to 6 days, though a full charge takes 180 minutes.
