Abstract

See full text

An electret type vibration detection system has a vibration-powered generator that performs vibration-induced power generation by displacing on a basis of external vibration an electret group formed of a plurality of electrets and an electrode group having a plurality of electrode pairs in a relative movement direction to output a vibration-induced voltage between electrodes of the electrode pair, and a transfer function memory section that stores transfer function information that defines a correlation between a vibration velocity of the external vibration and an output power voltage of the vibration-powered generator in a range of a predetermined frequency included in the external vibration, wherein the transfer function information contains a transfer coefficient set according to each of a plurality of frequencies belonging to the predetermined frequency range to place the vibration velocity of the external vibration and the output power voltage of the vibration-powered generator in a predetermined proportional relationship.
