Abstract

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 YE0 and mechanical loss factor Q–1m are a function of the square of effective vibration velocity v0. 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.
