Piezoelectric (adjective)

Describing materials or devices that generate an electrical charge when subjected to mechanical stress or pressure and conversely, that undergo a mechanical deformation when an electric field is applied to them.

Origin:

The word piezoelectric comes from the greek word "piezein" meaning to press or squeeze, and "electric" referring to the electrical charges generated by mechanical stress or pressure.

Examples:

1. The quartz crystal used in watches is a piezoelectric material.
2. Piezoelectric sensors are used to measure pressure and force.
3. The piezoelectric effect is used in the generation of electricity in some power plants.
4. Piezoelectric actuators are used in inkjet printers.
5. Piezoelectric transducers are used in ultrasonic imaging.
