Input Impedance Analysis of Piezoelectric Cylinder Transducer using Finite Element Method

This study shows how the finite element method for the structural problems could be applied in the electromechanical impedance analysis of an in-air piezoelectric cylinder transducer and then compares the numerical results by the FEM with the measured results using the impedance analyzer. The results also show that the comparison between both results could be applied to examine the mechanical properties of the added unknown material to transducer such as an acoustic window.
