Structural design and response analysis of piezoelectric power by flow-induced vibration

A vibration force acts on piezoelectric material, which will deform to-and-from and excite electricity on its polar surfaces. In this paper, the air resonance structure is designed by the principle of air self-oscillation, when the shells are flying with high-speed, the air into the shells will produce self-excited oscillation, the oscillation frequency only relates to the structure of the resonator rather than the speed of the wind which causes the oscillation of piezoelectric ceramics to produce a continuous charge, storage devices are used to store the charge, as regulated, the voltage is used as the power supply circuits of the fuse circuit.
