Energy Transfer to Piezoelectric Component Through Magnetic Resonant Coupling

Conference paper
Part of the Advances in Intelligent Systems and Computing book series (AISC, volume 308)

Abstract

In this paper, a non-contact energy transfer method has been experimentally investigated to drive a piezoelectric component operating in the thickness vibration mode. The energy transfer system uses a receiving coil connected to the piezoelectric component placed away from an energy-transmitting coil along its central axis. The impedance characteristics and frequency characteristics of the voltage developed across the piezoelectric component operating in the thickness vibration mode are experimentally investigated. It is observed that a mechanical resonance vibration is excited in the driven piezoelectric component through strongly coupled magnetic resonance between the coils as well as due to the mechanical resonance of the piezoelectric component. It has been found that the voltage developed across the piezoelectric component is maximum at its resonance frequency. It is also found that the energy received by the piezoelectric component connected to the receiving coil depends on the operating frequency, coil design, and distance between the coils.
