摘要

This paper presents an easy method of embedding piezoceramic transducer (PZT) and its implementation in electromechanical (EM) impedance based health monitoring of concrete structures. The basic principle used in this monitoring is to record EM admittance signatures acquired from the actuations of PZT transducer in the presence of electric field. Any deviations in these signatures during the monitoring period indicate disturbance/ damage in the structure. The PZT can be either surface bonded or embedded, however the important features of embedding PZT inside the host structure are durability and protection from surface finish, vandalism and environment attacks. The embedment of PZT in the structure is not as simple as surface bonding because there are several issues such as bonding between PZT and host structure. Moreover, it should withstand the curing pressures and temperatures of the host material. This paper is also expected to be useful for monitoring embeddable composite structures.
