Engineering structures can be classified into two categories based on their stiffness, those which are more stiff than and those which are less stiff than the PZT material. Surface bonded PZT transducers are more efficient when they are stiffer than the host structure, and embedded transducers are more efficient when they are less stiff than the host structure. Both types of PZT transducers are important in the EMI based NDE of the two categories of engineering structures. However, surface bonded PZT transducers have seen more prominent applications in the recent past in SHM. This research...
