Lead Zirconium Titanate (Ceramic)
Laser cutting material PZT substrates are the most widely used piezoelectric ceramic material. Piezoelectric materials acquire a charge when they are compressed, twisted or distorted in some way. This effect can be switched on and off. It than therefore be used as a transducer converting a non-electrical signal into an electrical one and vice-versa. When an electrical signal is applied to a PZT crystal it will mechanically vibrate providing a source of ultrasound.

Used in sensor and actuator manufacture. High-value ceramic capacitors and FRAM chips.
Thicknesses up to 2mm can be cut by laser with tolerances in the region of +/-0.02mm.
