MIT News: Ultrathin fuel cell uses the body’s own sugar to generate electricity

Energy from the human body ? Engineers at MIT and the Technical University of Munich have designed a new kind of glucose fuel cell that converts glucose directly into electricity. The device is smaller than other proposed glucose fuel cells, measuring just 400 nanometers thick, or about 1/100 the diameter of a human hair. As such, they could fuel miniature implants and sensors. The sugary power source generates about 43 microwatts per square centimeter of electricity, achieving the highest power density of any glucose fuel cell to date under ambient conditions. The inspiration for the new fuel cell came in 2016, when an engineer specialized in ceramics and electrochemical devices, went to take a routine glucose test toward the end of her pregnancy.
