Abstract

Three-dimensional graphene foam (GF) is synthesized by CVD. When water flows through GF, electricity is induced. The direction of the induced current is dominated by the flow direction of water; the value of induced current is related to the flow velocity but has no relationship with the flow direction and external bias voltage.
