This chapter reviews the sequential evolution of PZT-structure interaction models starting from 1D models, followed by 2D and 3D PZT-structure electromechanical formulations. In all these models, impedance is defined as 1D, 2D and 3D equations depending on the nature of host structure to be monitored, size of PZT patch and adhesive layer. In addition, direct use of coupled field element in conjunction with finite element method (FEM) is covered.
