Abstract
A piezoelectric power generator including a resonator having a first weight member supported on a base member by a spring; a second weight member; and a generating device having a vibrating plate with a piezoelectric element attached to a surface thereof. Further, the vibrating plate has one end secured to the first weight member and the other end being a free end attached to the second weight member. The generating device is capable of bending and vibrating in an up-and-down direction, such that the first weight member can swing at a predetermined frequency about an axis perpendicular to a bending vibration plane of the generating device.
