The traditional one-dimensional (1D) electromechanical impedance model simplifies the PZT as a thin bar, only considering the vibration in the axial direction, and the vibrations in other two directions are neglected. In this study, the vibrations of the PZT patch in x and z directions are taken into account to model the electromechanical coupling interaction between the PZT transducer and the host...
Piezoelectric lead zirconate titanate (PZT) transducer in the electromechanical impedance (EMI) technique has emerged as a potential sensing tool for structural health monitoring. In the EMI technique, PZT acts as both sensor and actuator simultaneously due to its direct and inverse piezoelectric effects. The EMI method using PZT transducers provide a new way for in-situ nondestructive testing of...
