While power generation at graphene-fluid interface is promising as an energy source for sensors, the weak generated electrical current necessitates an improvement in output power. The purpose of this study was to control carrier density through the application of a gate voltage and evaluate the changes in the generated electrical current. The modulation of the generated electrical current by the gate voltage suggests that the type and density of carriers in the graphene are affected, demonstrating that the output of the power generation device exploiting this phenomenon can be increased using a gate voltage.
