Abstract
A self-powered generator is provided. The generator includes a piezoelectric nanorod member layer that includes a first layer; a second layer; and a plurality of piezoelectric nanorods disposed between the first and second layers. The piezoelectric nanorod is a biaxially-grown nanorod. When mechanical energy is applied from an outside, an upper half and a lower half of each of the plurality of piezoelectric nanorods generate piezoelectric potentials having opposite polarities, the upper half and the lower half being on both sides of a longitudinal axis along an axis perpendicular to the longitudinal axis.
