Title:
VIBRATION POWER GENERATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/131369
Kind Code:
A1
Abstract:
A vibration power generation device, according to the present invention, includes: a vibration power generation element that generates power according to the vibration of an electrode; an output unit that, when connected to a load resistor, extracts the power generated by the vibration power generation element; a determination unit that determines whether or not the power value of said power is greater than a prescribed threshold; a decision unit that decides the input impedance of the output unit on the basis of the determination result from the determination unit; and an adjustment unit that adjusts the input impedance of the output unit according to the decision made by the decision unit.
