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.

Noun

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 crystalpiezo effect, piezoelectricityelectricity - a physical phenomenon associated with stationary or moving electrons and protons

piezoelectric effect

(pīē'zōĭlĕk`trĭk), voltage produced between surfaces of a solid dielectric (nonconducting substance) when a mechanical stress is applied to it. A small current may be produced as well. The effect, discovered by Pierre Curie in 1883, is exhibited by certain crystals, e.g., quartz and Rochelle salt, and ceramic materials. When a voltage is applied across certain surfaces of a solid that exhibits the piezoelectric effect, the solid undergoes a mechanical distortion. Piezoelectric materials are used in transducerstransducer,
device that accepts an input of energy in one form and produces an output of energy in some other form, with a known, fixed relationship between the input and output. One widely used class of transducers consists of devices that produce an electric output signal, e.g.

Piezoelectric solids typically resonate within narrowly defined frequency ranges; when suitably mounted they can be used in electric circuits as components of highly selective filters or as frequency-control devices for very stable oscillatorsoscillator, electronic

piezoelectric effect

[pē¦ā·zō·ə′lek·trik i′fekt] (solid-state physics) The generation of electric polarization in certain dielectric crystals as a result of the application of mechanical stress. The reverse effect, in which application of a voltage between certain faces of the crystal produces a mechanical distortion of the material.

piezoelectric effect

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.
