Abstract

Conventional design for piezoelectric transducers tends to favor materials with high electromechanical coupling coefficient. However, when the converse piezoelectric effect is used in the design of transducers for maximum mechanical displacement, transducer performance measured by power conversion depends also on other factors such as the type of acoustic wave generated and material constants. An analysis of a piezoelectric transducer shows that maximum mechanical displacement is inversely proportional to the dynamic electromechanical coupling coefficient and the square of acoustic wave velocity. This implies that a slow shear wave in a material having low electromechanical coupling is preferred. Simulation results of different materials for transducer and substrate are presented.
