Recently the concept of Piezo-Electro-Mechanical (PEM) structural member has been developed. Given a structural member, a set of piezoelectric actuators if uniformly distributed on it and electrically interconnected by one of its analog circuits. In this way it is obtained a high-performances piezoelectric structural-modification aiming to multimodal mechanical vibrations control. In the present paper it is addressed the problem of synthesizing an electrically dissipative PEM Kirchhoff-Love (K-L) plate by using completely passive electric networks.
