piezoelectric effect

(paɪˌiːzəʊɪlɛkˈtrɪsɪtɪ) or

piezoelectricity

n
(General Physics) physics
a. the production of electricity or electric polarity by applying a mechanical stress to certain crystals
b. the converse effect in which stress is produced in a crystal as a result of an applied potential difference
piˌezoeˈlectrically adv

pi·e·zo·e·lec·tric effect

(pī-ē′zō-ĭ-lĕk′trĭk)
The generation of an electric charge in certain nonconducting materials, such as quartz crystals and ceramics, when they are subjected to mechanical stress (such as pressure or vibration), or the generation of vibrations in such materials when they are subjected to an electric field.
ThesaurusAntonymsRelated WordsSynonymsLegend:
Noun1.piezoelectric effect - electricity produced by mechanical pressure on certain crystals (notably quartz or Rochelle salt); alternatively, electrostatic stress produces a change in the linear dimensions of the crystal
electricity - a physical phenomenon associated with stationary or moving electrons and protons
