Stability of the piezoelectric properties with changing vibration level was studied in lead zirconate-titanate (PZT) ceramics by using the constant-current/velocity driving method. The changes of Young's modulus Y[sub 0][sup E] and mechanical loss factor Q[sub m][sup [minus]1] are a function of the square of effective vibration velocity v[sub 0]. The nonlinear proportional constants of the above functions indicate the degree of stability under vibration level change. The stability of PZT estimated by these constants coincides with the results obtained through the heat generation study.
