Title:

Piezo-electricity type oscillating power generator

Document Type and Number:

Japanese Patent JP6179851

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To provide a piezoelectric type vibration power generating device capable of adding an exciting force without being restricted by durability with respect to deformation of a piezoelectric substance.SOLUTION: A piezoelectric type vibration power generating device 10 includes a plate piece 12 which is extended in a cantilever state while being fixed to a support part 16 and in which a width W1 on a fixed end 12k side is smaller than a width 2 on a free end 12J side or equal thereto; and a piezoelectric substance 14 which is mounted on the plate piece 12 and generates power by distortion generated by being deformed together with the plate piece 12 when the plate piece 12 receives an exciting force or forcible displacement.
