Abbreviation (not acronym) for Lead Zirconate Titanate, a popular piezoelectric ceramic with ferroelectric properties.

PZT is a perovskite ceramic. It is commonly used as the active material in piezoelectric transducers, which are often mistakenly (and ironically) referred to as PZTs. Such transducers include nanopositioning systems, microphones, and MEMS devices.
