Levitation caused by the vertical vibration of a piezoelectric actuator is studied here. Levitation mechanisms levitate using a squeeze effect generated by the vertical vibration. The levitation mechanisms usually levitate at the resonance frequency. However, if the vibration amplitude of the piezoelectric actuator at the resonance frequency is small, the levitation mechanism does not levitate. Therefore, the vibration amplitude affects the levitation height of the mechanism. In this paper, we describe the applied voltage, the load current, the power consumption, and the phase difference between the voltage and current.
