Document Type and Number:
WIPO Patent Application WO/2022/130767
Kind Code:
A1
Abstract:
Provided is a vibration power generation device in which it possible to increase the power generation efficiency of the vibration power generation device even when vibration changes. The vibration power generation device includes: a vibration power generation element that generates power corresponding to electrode vibration; an output unit that supplies the power generated by the vibration generation element to a load resistor when connected to the load resistor; and an adjustment unit that adjusts the input impedance of the output unit in accordance with a signal corresponding to the acceleration of the vibration.
