ENERGY HARVESTING SYSTEM

摘要

PURPOSE: An energy harvesting system is provided to obtain the maximum generation power by configuring a piezoelectric module to have a resonance frequency coinciding with the fixed impulse frequency given by an impulse module. CONSTITUTION: An impulse module(110) includes an impulse member(111). A piezoelectric module(150) generates electric energy by impulse applied by the impulse member. The piezoelectric module includes a piezoelectric device and piezoelectric body(160). The piezoelectric body has a support member. The piezoelectric device is attached to the support member. The bending length or thickness of the piezoelectric body is controlled. The bending length or the thickness of the piezoelectric is controlled.
