ABSTRACT

Piezoelectric materials have been used extensively in resonator, actuator, and ultrasonic receiver applications,

while ferroelectric materials have recently received much attention for their potential use in nonvolatile (NV)

memory applications.Wewill discuss the basic concepts in the use of thesematerials, highlight their applications,

and describe the constraints limiting their uses. This chapter emphasizes properties which need to be understood

for the effective use of these materials. Among the properties discussed are hysteresis and domains.
