Food‐Materials‐Based Edible Supercapacitors

Abstract

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. As a service to our authors and readers, this journal provides supporting information supplied by the authors. Such materials are peer reviewed and may be re-organized for online delivery, but are not copy-edited or typeset. Technical support issues arising from supporting information (other than missing files) should be addressed to the authors.
