Abstract :
In this paper, a new method has been developed to characterize the electromechanical properties of relaxor-PT piezoelectric crystals. In this method, 5 Z-cut samples were used to measure all the eleven electromechanical coefficients of the relaxor-PT piezoelectric crystals by the resonant method. In addition, a technique incorporating laser interferometry was used to precisely measure the piezoelectric constants d33 and d31
