Title:
WEIGHT FOR POWER GENERATOR
Document Type and Number:
Japanese Patent JP2015122951
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To make a weight that is used for a power generator using a piezoelectric element, generates power in a piezoelectric element using a vibration and a collision, is capable of generating power more efficiently than the conventional ones, and is a material hardly corroded owing to an environment.SOLUTION: A weight 1 used for a power generator 10 using a piezoelectric element 3 is manufactured with an alloy of tungsten and an iron group metal or with an alloy of tungsten, an iron group metal, and copper. Compared with a weight made of an iron material or a lead material, power may be generated more efficiently, a space may be more saved, and environmental contamination may be avoided. Compared with a weight made of tungsten material, a weight is obtained that may be manufactured more inexpensively and is more resistant to corrosion owing to a use environment.
