In this paper, a type of hysteretic constitutive model of piezoelectric sensor was proposed. Nonlinear differential terms were developed to express the hysteresis phenomena of displacement-voltage relationship of piezoelectric ceramics. Based on the model, the dynamic model of a PZT sensor was established. The nonlinear dynamic behaviours of a PZT sensor were analyzed, and the relationship between the outside excitation and the voltage of a PZT sensor was obtained. Theoretical results show that there are many kinds of frequencies in the output voltage, which are caused by the PZT’s hysteresis characteristics.
