The patch-generator will receive the energy of the human body during sleep ⚡
This is the development of scientists from San Diego, California. A thin strip of carbon foam is glued to the finger. The enzymes inside the foam come into contact with sweat, resulting in the reaction of oxygen and lactate molecules and the production of electricity. During a 10-hour sleep, the fingers of the volunteers developed up to 400 millijoules each, and this is enough for almost a day of operation of the smart watch. Multiply by the number of fingers and add that you can carry the generator around the clock-here’s a free personal power station for you.
