Abstract :
Equivalent piezoelectric actuator circuit is necessary for certain applications. Previous models have limits and are not accurate on modelling the real part of piezo impedance at low frequency range. A simple inverse proportional to frequency model is proposed and experimentally validated. The comparison with other models show also it is the most robust model.
