A Battery Powered by Bacteria and Sweat

Researchers from the University of Massachusetts Amherst have engineered a bacteria-based battery that can produce power from human sweat. The key to their innovation is bacterium Geobacter sulfurreducens, a bacteria that can produce electricity and has been used to explore microbial batteries. However, its need to be fed a constant diet has limited its functionality. To get around this, the researchers grew the bacteria sustainably …
