Piezoelectric transducers are being commonly used for sensing and actuation applications for smart structural systems. In particular, they are widely used for structural health monitoring (SHM) thanks to such attractive characteristics as multi-functionality, nonintrusivity, light weight, low cost, rapid response time, and high repeatability. This chapter first deals with the basic principles of piezoelectric transducers and the characteristics of piezoelectric materials. Subsequently, various piezoelectric transducer-based SHM methodologies including guided wave, impedance, and acoustic emission techniques are summarized. Then, their state-of-the-art applications to SHM fields are presented. Future trends are also discussed in this chapter.
