Résumé
Piezoelectric materials are widely used for many applications such as sensors, actuators. Today, their integration in microelectronics processes like CMOS [1] requires the development of advanced realistic behavioral models. Until now, these models were limited to only one ceramic's operation mode, i.e., thickness or planar. Moreover, the robustness of piezo-electronic systems cannot be adequately addressed as long as models are not improved in particular by taking into account further real phenomena. This article proposes to merge, in a new KLM model, the two operation modes. It is demonstrated that the behavior of the proposed model is in very good agreement with the real ceramic behavior.
