A quasi-solid-state and self-powered biosupercapacitor based on flexible nanoporous gold electrodes†
Abstract
A quasi-solid-state and flexible biofuel cell using a hydrogel electrolyte preloaded with sugar as a fuel is described. The device can function as a self-powered biosupercapacitor delivering pulses for over 600 cycles, with a power density over 10 times higher than that from the biofuel cell alone.
