Abstract
Piezoelectricity underpins a very large proportion of the ultrasonic transducers in use and in development today. This chapter first reviews ferroelectricity and piezoelectricity in an ultrasonic context, particularly focusing on the constitutive equations, then describes the configurations of basic piezoelectric transducers in the form of single- and dual-element devices, arrays and Langevin transducers. Ancillary components within these structures are outlined, along with mathematical analysis where appropriate.
