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.
