Abstract
An exemplary energy harvester includes a piezoelectric diaphragm, an eccentric mass that rotates in response to external motion, and a piezoelectric stress inducer coupled with the eccentric mass and the piezoelectric diaphragm. The piezoelectric stress inducer deforms the piezoelectric diaphragm in response to rotational motion of the eccentric mass, causing the piezoelectric diaphragm to generate electrical energy.
