RING (1) is a design concept for NOTHING (R)
The self sufficient SmartRing collects health data like heart rate, body temperature and walking distance. Its striking feature however is its charging capabilities. By making use of lactate, a natural byproduct of anaerobic respiration (sweat) that can be broken down by enzyme, to make energy.
Inspired by translucent plastic, NASA and NOTHING design
By making use of lactate, a natural byproduct of anaerobic respiration (sweat) that can be broken down by enzyme, the ring makes it's own energy.
A small opening on the inside cover of the Ring (1) allows the enzymes to make contact with the needed lactate to recharge the battery.

One of the rings most important capabilities is the removable battery.
Today's wearable tech is often glued shut and therefore impossible to repair. The RING (1) trades a high IP rating for a high repairability. 
Two shells are held together by adhesive. The circuit board with all its sensors is bendable and can be taken out of the rings frame easily. The battery itself is connected with a lego-style ribbon cable, making a replacement a pleasant experience.
