Key Takeaway

Key Takeaway: The biosupercapacitor, using flexible nanoporous gold electrodes and sugar-loaded hydrogel electrolyte, can provide over 600 cycles of pulsed power with a power density over 10 times higher than a biofuel cell alone.

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.
