PZT

Lead zirconate titanate

PZT is lead zirconate titanate, a ceramic material prized for its piezoelectric properties—it generates electricity when mechanically stressed and changes shape when electrically stimulated.

PZT appears in ultrasound transducers, precision actuators, sensors, and audio equipment like buzzers and microphones.

The abbreviation comes from the chemical formula Pb(Zr,Ti)O₃, where Pb is lead.
