Abstract :
Information regarding the properties of resonators of various rotations of poled PZT-5A was obtained. These devices possess both quasi-longitudinal and quasi-shear resonances. The elastic, dielectric, and piezoelectric constants of PZT-5A rotated 45° and 60° from the direction of poling are presented. In addition, the electromechanical coupling values for both modes is given for the 180° plane in PZT-5A. Experimental values have been determined and are compared with theoretical values
