Abstract
Provided is a self-resonance tuning piezoelectric energy harvester. The self-resonance tuning piezoelectric energy harvester includes a piezoelectric beam which extends along a horizontal direction, a fixing element which fixes two ends of the piezoelectric beam, and a mass which is connected to the piezoelectric beam movably along the piezoelectric beam, wherein the mass includes a through-hole through which the piezoelectric beam passes, and makes the movement through the through-hole. According to the principle of continuous movement to the resonance position, the mass of the self-resonance tuning piezoelectric energy harvester induces the piezoelectric beam to generate displacement to the maximum and maximize the electricity production capacity of the piezoelectric energy harvester.
