Nowadays, it is expected that vibration power generator is used as autonomous power supply of wireless sensor network. Mechanical resonant vibration power generator is high efficiency when environmental vibration is near the resonant frequency. However, displacement of moving part of generator is large at low frequencies. To miniaturize a generator, it is necessary that a generator is changed translation mechanism into rotary mechanism. Over the past few years, several studies have been made on vibration power generation using self-excited rotation or gyro effect. In comparison with self-excited rotation or gyro type, a resonance type generator has an advantage of being a simple structure. So, we develop the resonant rotary vibration power generator to attain miniaturization of the generator. In this paper, we report the mathematical model of the resonant rotary vibration power generator and results of evaluating the prototype.
