Piezoelectric power generating device having a stress applying member

摘要

A piezoelectric power generating device that includes a piezoelectric element having a first surface and a second surface opposite the first surface, a stopper, and a lever. The stopper has a first contact surface that is in contact with the first surface. The lever includes a contact portion, which includes a second contact surface that is in contact with the second surface, and a displacement portion. The lever is arranged in such a manner as to be rotatable relative to the stopper around a rotation axis such that the second contact surface presses the second surface when the displacement portion rotates relative to the stopper around the rotation axis.

1. A piezoelectric power generating device comprising:
a piezoelectric element extending along a first direction and having a first surface and a second surface opposed to the first surface; a stopper having a stopper contact surface in contact with the first surface of the piezoelectric element; and a lever including a contact portion having a lever contact surface in contact with the second surface of the piezoelectric element and including a displacement portion positioned adjacent the first surface of the piezoelectric element such that the stopper contact surface is between the displacement portion and the first surface of the piezoelectric element, the lever being rotatable relative to the stopper around a rotation axis extending in a second direction perpendicular to the first direction.
