Due to the great bulk of the piezoelectric air resonance generator, it is difficult to achieve resonance and the output voltage is low. In this case, a novel micro air driven fluidic resonance generator based on common jet generator principles and MEMS process technology is proposed. This generator use cantilever type piezoelectric vibrator instead of piezoelectric film for power generation. The FSI and Piezoelectric simulation results show that the new MEMS Piezoelectric Generator can meet the low cost requirement of fuze. Further more it has the features of simple structure, small size and high output voltage.
