The device wraps tightly around the finger and uses natural sweat as an energy source. It uses special bioelectric cells in the area where the finger touches it to convert chemicals in sweat into electricity. This energy is stored in flexible batteries and powers sensors that measure things like glucose, vitamin C, lactate and levodopa.
The improved headband also allows you to continuously monitor your health even when resting or sleeping by transferring data via Bluetooth to a special application. In the future, it is planned to create a system that will not only monitor indicators, but also prescribe treatment according to the collected data.
