Document Type and Number:
Japanese Patent JP6388163
Kind Code:
B2
Abstract:
A power generator including: a first vibration system in which a first mass member is elastically supported by a first spring member; and a second vibration system in which a second mass member is elastically supported by a second spring member, the first and second vibration systems providing a multiple-degree-of-freedom vibration system. A power generating element disposed between the first and second mass members is configured to convert vibration energy input to the first vibration system and the second vibration system from a vibrating member to electrical energy. A resonance frequency of the first vibration system is a frequency lower than 1/√2 times a frequency of a vibration input to the first vibration system from the vibrating member. A loss factor of the first spring member of the first vibration system is at least 0.01 but not greater than 0.2.
