A new wearable device that wraps around your finger like a plaster can harvest sweat while you sleep and use it to generate electricity, its developers claim. But the new strip uses a passive system to generate electricity from moisture in your fingertips, even if you are sleeping or sitting completely still, the team explained. The electrodes are equipped with enzymes that trigger chemical reactions between lactate and oxygen molecules in sweat to generate electricity. The device is equipped with electrical conductors - or electrodes, made from a carbon foam, which absorbs any finger sweat. Enzymes on the electrodes then trigger a chemical reaction between sweat molecules - lactate and oxygen, to generate electricity.
