The Smart Ring shows you the oxygen level in your blood
Although it looks like an
ordinary ring, the 'Oura' ring can detect the level of oxygen in the blood by
using an infrared LED sensor. In addition, it can also inform the user whether
they are sleeping well or not. Controlled via an app, all data collected by the
ring is known directly from the smartphone.
Even with the battery hooked
up, the ring weighs quite bit, solely half dozen grams. Since the ring is
waterproof, it can be showered afterwards. The ring, which can collect up to
seven days of data on a single charge, costs $299.
