Flexible Nanogenerators Based on Graphene Oxide Films for Acoustic Energy Harvesting

Abstract

Graphene oxide films were fabricated as low-cost and flexible nanogenerators to convert acoustic energy into electricity with a conversion efficiency of 12.1 % (see picture). The generated current sensitively depended on the pH value of the suspensions for graphene oxide (GO) film production.
