Abstract:
1. A piezoelectric power generator comprising: a first elastic body configured to deform upon receiving a stress, the first elastic body including: a piezoelectric power-generating element that includes a second elastic body arranged adjacent a first side of the first elastic body; and a vibration suppressing member arranged relative to the first elastic body and the second elastic body so as to suppress a bending mode vibration of the second elastic body, wherein the piezoelectric power generator is structured such that, when the first elastic body deforms into a shape that is concave relative to the first side of the first elastic body, the second elastic body receives a stress from the first elastic body and deforms into a concave shape, and when the first elastic body deforms into a shape that is convex relative to the first side of the first elastic body, the second elastic body does not receive a stress from the first elastic body, and wherein the first and second abutting portions abut against the second elastic body when the first elastic body deforms into the shape that is concave relative to the first side of the first elastic body.
