圧電型発電装置
Document Type and Number:
Japanese Patent JP6882096
Kind Code:
B2
Abstract:
To provide a power generator that has little secular change of a structure under a use environment and is capable of stable power generation for a long time.SOLUTION: A piezoelectric generator 1 includes a piezoelectric element 2, a support plate 3, and a pressing member 4. The support plate 3 has a first surface 3a and a second surface 3b opposite to each other, and a pair of fixing portions F1 and F2 arranged so as to be separated from and opposed to each other across a central portion of the support plate 3 in a first direction (x direction) of the first surface 3a. The piezoelectric element 2 is bonded to the first surface 3a of the support plate 3, and the pressing member 4 is an elastic body having a pressing surface 4a arranged along the second surface 3b of the support plate 3 and pressing the second surface 3b when a force is applied from the outside.SELECTED DRAWING: Figure 1
