Five-port equivalent electric circuit of piezoelectric bimorph beam

摘要

Abstract: A design for an equivalent electric circuit of three-layered piezoelectric bimorph is presented. The piezoelectric bimorph is modeled as a beam in which only bending deformation can be induced; thus, its end deflections and rotations are considered the ports of the equivalent electric circuit. The electromechanical impedance parameters of the equivalent electric circuit, which has a single electrical and four mechanical ports, are found.!29
