Related to piezoelectric effect: Piezoelectric transducer
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.
Etymology: Gk, piezein, to press, elektron amber; L effectus
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.
In ultrasound, a change of the mechanical action of ceramic crystals into an electrical impulse and vice versa.See: triboluminescence
