Engineered by a team from the University of California, San Diego, the strip has carbon foam electrodes that absorb sweat. A chemical reaction is then initiated between the lactate and the oxygen molecules, resulting in electricity generation. The strip generates energy through pressure. Activities like typing, driving, opening the refrigerator, and exercising also contribute to energy production. In addition, the strip generates enough energy to power an electronic watch for 24 hours.
