Hysteresis loops of the piezoelectric coefficient, d{sub 33}=f(E{sub 3}), are measured on virgin and fatigued lead zirconate titanate ceramics. Four parameters are directly extracted from the measurements: internal bias field E{sub b}, offset piezoelectric coefficient d{sub offset}, coercive field E{sub c}, and remnant piezoelectric coefficient d{sub r}. The reduction in d{sub r} displays the decreasing switchable polarization with fatigue cycling. E{sub b} and d{sub offset} are found to be linearly related. After thermal annealing, both offsets disappear, while the increase in E{sub c} and the reduction in d{sub r} withstand annealing. The microscopic entities responsible for the offsets are less stable than those for reduced switching.
