This Skin Patch Can Power A Radio For 2 Days Using Your Own Sweat
Researchers have created a new skin patch that has powered a radio for two days using only human sweat. The Biofuel Skin Patch uses the sweat to provide its power – meaning it could be used to charge up devices like phones in the near future.
“If you were out for a run, you would be able to power a mobile device,” said Joseph Wang from the University of California, San Diego.
His research team at the university have been working on the technology. The biofuel patch is a few centimeters wide and sticks directly on the skin.
It works by using enzymes that act like the metals inside regular batteries, which are then powered up by feeding off the lactic acid found in sweat.
