Food‐Materials‐Based Edible Supercapacitors

Electrochemically fully functional, edible supercapacitors are presented. All materials involved in generating the supercapacitors are explicitly originated from edible and nontoxic food products, including activated charcoal, seaweed, cheese, polyelectrolyte drink, and so on. The edible supercapacitors are demonstrated to kill disease-causing bacteria in vitro and to power a commercial snake camera, which renders huge potential to be used in novel biomedical devices.
