Abstract

Sound-driven power generation using nanogenerators based on piezoelectric ZnO nanowires has been demonstrated. Systematic investigations on the power-generating performance of sound-driven nanogenerators clearly support that the measured output voltage originated from the sound-driven nanogenerator. This study shows that sound can be one of promising energy sources when using highly efficient nanogenerators based on piezoelectric nanowires.
