UNIT FOR PIEZOELECTRIC GENERATOR AND GENERATOR SYSTEM INCLUDING THE SAME

摘要

A unit for a piezoelectricity generator and a piezoelectricity generator system are provided to prevent a piezoelectric object from being damaged due to the excessive impact and the connection. A first piezoelectric layer(100) and a second piezoelectric layer(130) are formed in both sides based on a substrate(160). The substrate has the property of being bent with the vibration or the press and the force of restitution. A circuit parts(140, 150) are formed by completing the upper part of the first piezoelectric layer and a unit for a piezoelectricity generator. The circuit part is equipped in the one-side upper part of the first piezoelectric layer. The circuit part arranges the unit for the piezoelectricity generator as matrix type and has circuit parts of each unit connected in order to be charged. A fixing unit(180) is formed on the substrate which is adjacent to the central part of the unit for the piezoelectricity generator. A moving part(170) is formed on the substrate which is adjacent to both edges of the unit. The fixing unit is supported in the lower part of the substrate. And the moving part is formed into the structure where substrate can be bent with a pressure pin. The first piezoelectric layer is equipped at the upper part of the first side of the substrate with bar type.
