Nanoengineers at the University of California San Diego have developed a “wearable microgrid” that harvests and stores energy from the human body to power small electronics. It consists of three main parts: sweat-powered biofuel cells, motion-powered devices called triboelectric generators, and energy-storing supercapacitors. All parts are flexible, washable and can be screen printed onto clothing.
The technology, reported in a paper published Mar. 9 in Nature Communications, draws inspiration from community microgrids.
“We’re applying the concept of the microgrid to create wearable systems that are powered sustainably, reliably and independently...
