Wellue Ring

A recent Medgadget article discussed the latest development in personal oxygen monitoring: a smart thumb ring. The device was developed by China-based medical device company Wellue, and it’s called the O2Ring. Composed of flexible medical grade silicone, the pulse oximeter contains a small LED screen that provides continuous peripheral oxygen saturation (SpO2) readings. The smart ring powers on automatically when slid on a finger, and powers off seconds after removal. Simply tap the screen, and it will illuminate to show your SpO2 and heart rate in real time. It costs $165, and can be purchased on Wellue’s website or Amazon.
