Imagine using daily exercise not just to power your body, but also your cell phone.
That’s what a team of scientists at the University of California-San Diego (UCSD) are working on, with the aid of a temporary tattoo that monitors a person’s progress during exercise and generates power from their sweat.
The tattoo detects lactate, a substance in sweat and “a very important indicator of how you are doing during exercise,” says Wenzhao Jia, a postdoctoral researcher at UCSD involved in the study. A report of her team’s findings was prepared for presentation on Aug. 13 at the 248th National Meeting & Exposition of the American Chemical Society in San Francisco.
