Abstract: Ultrasound based Structural Health Monitoring (SHM) commonly uses surface-bonded piezoelectric wafer active transducers (PWaTs) for ultrasound wave generation and sensing. Both the electromechanical impedance (EMI) of the surface bonded PWaT and the ultrasound pitch-catch signal… read more here.
