Piezoelectric Power Generator |
摘要 |
A piezoelectric power generator that includes a first elastic body, which deforms along a first direction x upon receiving a stress, and a piezoelectric power-generating element. A second elastic body is arranged on a y1 side of the first elastic body and a piezoelectric element is fixed to a y1-side surface of the second elastic body. When the first elastic body bends into a shape that is concave toward the y1 side, the second elastic body receives a stress from the first elastic body. When the first elastic body bends into a shape that is convex toward the y1 side, the second elastic body does not receive a stress from the first elastic body. The piezoelectric power generator further includes a vibration suppressing member that is arranged between the first elastic body and the second elastic body and suppresses bending mode vibration of the second elastic body.
