Abstract：The permanent magnet vibration generator has low output power,and it is infuluenced by environmental vibration. Thus, a low power comsumption circuit is contrived to process the energy and improve the efficiency of power supply. The output voltages are measured when experimenter swing his arms. The power spectral density is calculated for revealing the bandwhich the output energy is concentrated in. Based on this, calculate the impedance of the permanent magnet vibration generator and design the circuit. The circuit contains the filter circuit, energy storage and supply circuit. The experimental results show that only no more than 30μW is consumed by the circuit.
