Problems solved by technology

[0016] As a result, there is a problem that vibration occurs in a direction other than the desired direction with respect to external vibration.
[0017] In addition, compared to the case where a silicon substrate, a glass substrate, etc. are used as the first substrate 21, the resin spring 29 is formed of a resin such as parylene that is completely different from silicon and glass, so there are differences in structure, Issues such as process complexity

Abstract

Provided are a vibration power generator, a vibration power generation device, and an electronic device and a communication device having vibration power generation device installed, wherein a complex structure or process is not necessary, mechanical reliability is improved, and lower frequencies can be dealt with. The vibration power generator comprises a first substrate, a first electrode arranged upon the first substrate, a second substrate separated from and facing the first substrate, and a second electrode arranged upon the second substrate. The first substrate can vibrate with respect to the second substrate, and either the first electrode or the second electrode comprises an electric-charge carrying film. The vibration power generator further comprises a third electrode arranged upon the first substrate and containing an electric-charge carrying film, and a fourth electrode arranged upon the second substrate and containing an electric-charge carrying film, and the third and fourth electrodes are arranged so that the first substrate is held at a prescribed position when there is no external force applied thereto, and when there is external force applied to the first substrate and the first substrate is moved with respect to the second substrate, an electrostatic force is applied to return the first substrate to the prescribed position.

Description

technical field [0001] The present invention relates to a kind of vibration power generator and a kind of vibration power generation device, a kind of communication device and electronic equipment loaded with vibration power generation device, especially relate to a kind of electrostatic induction type vibration power generator utilizing electret (electret) material and A vibration power generation device, a communication device and electronic equipment loaded with the vibration power generation device. Background technique [0002] As a conventional vibration power generation device, an electrostatic induction type vibration power generation device is known in which charge is applied to one electrode of a variable capacitor and the charge is induced to the opposite electrode by electrostatic induction. The induced charge is changed by the change of capacitance. An electrostatic induction type vibration power generator extracts this change in electric charge as electric ene...
