Abstract

In this paper, a transducer that is suitable for the ultrasonic wireless power transmission system is discussed. The transducer is designed based on Mason's equivalent circuit theory, basically. The transducer was developed using design parameters optimized by multiphysics analysis. As a result, it is confirmed that the transmission efficiency is drastically improved to more than 50%. This result suggests that wireless power transmission by acoustic wave is feasible.
