Abstract
In this paper, a 2D axisymmetric model was built to observe the acoustic field and electric potential distributions during the energy transmission process from a piezoelectric layer to a metal plate. The effect of dimension of the piezoelectric transducer on the energy transmission is compared and analyzed by using the COMSOL multiphysics. Then, an experimental platform is instituted to verify the feasibility of the method of energy transmission by acoustic wave through a metal plate. Based on the finite element simulation and experimental test, it is found that the power conversion efficiency is related to the size of the transducer, the thickness of the metal plate, and other parameters. It is shown by experimental measurement that the conversion efficiency could be reached about 30%.
