This is the Dreame AI Smart Ring: a new smart wearable device for health and sleep tracking. It has an aerospace-grace ceramic construction with a micro-vibration motor and can track your heart rate variability and blood oxygen level. It also features motion and activity tracking. You can use it as a tool to interact with your music and presentations with simple taps and gestures.
This ring works passively, so you don’t need to use a smartwatch to track your sleep. As you can see in the above video, it is possible to track your data on your smartphone. This ring has a 2.5mm profile, so it looks like a piece of jewelry and not a high-tech gadget.
