Related to piezoelectric effect: Piezoelectric transducer

pi·e·zo·e·lec·tric ef·fect

the property of certain crystalline or ceramic materials to emit electricity when deformed and to deform when an electric current is passed across them, a mechanism of interconverting electrical and acoustic energy; an ultrasound transducer sends and receives acoustic energy using this effect.

1 the generation of a voltage across a solid when a mechanical stress is applied.
2 the dimensional change resulting from the application of a voltage.
3 (in ultrasound) the conversion of one form of energy into another, such as the conversion of electrical energy into mechanical energy.

piezoelectric effect

(pe-a'zo-e-lek'trik)
