Title:
圧電発電装置
Document Type and Number:
Japanese Patent JP5422676
Kind Code:
B2
Abstract:
An object is to provide a piezoelectric generator for increasing the energy conversion efficiency in converting vibration into electricity. A piezoelectric generator 1 includes a fixing part 2, a cantilever 3 formed on the front end of the fixing part 2, a weight part 4 formed at a front end of the cantilever 3, a centroid adjustment part 5 by which a position of a centroid of the weight part 4 is adjusted, and a piezoelectric generating cell 10 formed on top of the cantilever 3. The centroid of the weight part 4 is set a position at which the power generation efficiency is increased.
