VIBRATING MINI-ENERGY SCAVENGER

摘要

A vibration type micro generation device is provided to increase vibration amplitude without increase of a size by changing a shape of a piezoelectric device. A vibration type micro generation device comprises a base(100), a plurality of piezoelectric device(110), an electrode(120), and a connection vibration plate(130). The piezoelectric device is formed into a plate shape. One side of the piezoelectric device is connected to the base. The piezoelectric device is protruded to an outer side of the base. The electrode is formed on both sides of the piezoelectric device. The connection vibration plate is formed on the other side of the piezoelectric device, and is connected to an adjacent piezoelectric device. A weight is coupled in the connection vibration plate, and slides according to the connection vibration plate. The connection vibration plate includes a coupling part and a vibration part. The coupling part is coupled in the piezoelectric device. The vibration part connects the coupling part each other.
