Abstract:
(EN) The present invention relates to a unit for a piezoelectric generator and to a piezoelectric generator system comprising same. The unit for a piezoelectric generator comprises: a substrate being characteristically bent by the pressure or vibration applied to a surface thereof, and having a restoration force countering the bendable characteristic; a first piezoelectric layer which is formed on a first surface of the substrate, has a first area, and is formed once or multiple times; a second piezoelectric layer which is formed on a second surface of the substrate opposite the first surface, having a second area narrower than the first area, and formed such that a portion of the area thereof or the entirety of the area thereof can be overlapped with the first piezoelectric layer; and a circuit unit formed on the first piezoelectric layer which is not overlapped with the region in which the second piezoelectric layer is formed, such that a portion of the area thereof or the entirety of the area thereof can be overlapped with the first piezoelectric layer.
(FR) La présente invention porte sur une unité pour générateur piézo-électrique et sur un système de générateur piézo-électrique la comprenant. L'unité pour générateur piézo-électrique comprend : un substrat qui est fléchi de façon caractéristique par la pression ou vibration appliquée à une surface de celui-ci, et ayant une force de rappel s'opposant à la caractéristique cintrable ; une première couche piézo-électrique qui est formée sur une première surface du substrat, a une première aire, et est formée une fois ou plusieurs fois ; une seconde couche piézo-électrique qui est formée sur une seconde couche du substrat opposée à la première surface, ayant une seconde aire plus petite que la première aire, et formée de telle manière qu'une partie de son aire ou la totalité de son aire peut être chevauchée par la première couche piézo-électrique ; et une unité de circuit formée sur la première couche piézo-électrique qui n'est pas chevauchée par la région dans laquelle la seconde couche piézo-électrique est formée, de telle manière qu'une partie de son aire ou la totalité de son aire peut être chevauchée par la première couche piézo-électrique.
