A Unified Electrical SPICE Model for Piezoelectric Transducers

Abstract

The widespread use of piezoelectric materials in an increasing number of applications requires the development of advanced realistic electrical models. Until now, models were limited taking into account only one ceramic's operation mode, i.e., thickness or planar. On the other hand, it establishes that the robustness of the piezo-electronic systems is likely to weaken if the models making it possible to conceive do not improve, in particular by taking into account further real phenomena. This article proposes to merge, in a new electrical model, the two operation modes. It is demonstrated that the electrical behavior of the proposed model is in very good agreement with the real ceramic behavior.
