Title:
圧電デバイス、センサ装置および発電装置
Document Type and Number:
Japanese Patent JP6677589
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To further heighten an electric charge generation rate.SOLUTION: The piezoelectric device comprises a first fixation part, a first weight part, a first connection part, a second fixation part, a second weight part, a second connection part and a restraint part. The first weight part is separate from the first fixation part and located in the lateral direction of the first fixation part. The first connection part connects the first fixation part and the first weight part together, and is bendable so as to cause the first weight part to be displaced in a downward direction by an external force. The second weight part is separate from the second fixation part and located in the lateral direction of the second fixation part, and is located above the first weight part. The second connection part connects the second fixation part and the second weight part together, and is bendable so as to cause the second weight part to come in contact with the first weight part by an external force, with electric charges generated by curvature. The restraint part is located downward of the first weight part apart from the first weight part, and restrains the first weight part and the second weight part from being displaced in the downward direction.SELECTED DRAWING: Figure 2
