Research on Piezoelectric Power with High Transfer Efficiency

Based on the performance of piezoelectric materials, a parallel multi-layer piezoelectric power structure is designed and the experiment verifies the performance of piezoelectric material to generate electricity And then, it designs voltage stabilizing circuit. Experimental result shows that combination of parallel multi-layer mode design of piezoelectric power with the bridge rectifier circuit can charge twice power for storage capacitor and reduce the voltage generated by piezoelectric materials; it enhance the current and energy transfer efficiency of piezoelectric materials; therefore, it raises storage capacitor voltage, which can be used as some of the power circuit.
