  • Metal disk with piezoelectric disk attached, used in a [[buzzer]]
  • Any spatially separated charge will result in an [[electric field]], and therefore an [[electric potential]]. Shown here is a standard dielectric in a [[capacitor]]. In a piezoelectric device, mechanical stress, instead of an externally applied voltage, causes the charge separation in the individual atoms of the material.

piezoelectricity         
¦ noun electric polarization produced in certain crystals by the application of mechanical stress.
Derivatives
piezoelectric adjective
piezoelectrically adverb
Origin
C19: from Gk piezein 'press, squeeze' + electricity.
Piezoelectric speaker         
TYPE OF LOUDSPEAKER
Piezoelectric speakers; Piezo sounder; Piezoelectric loudspeaker
A piezoelectric speaker (also known as a piezo bender due to its mode of operation, and sometimes colloquially called a "piezo", buzzer, crystal loudspeaker or beep speaker) is a loudspeaker that uses the piezoelectric effect for generating sound. The initial mechanical motion is created by applying a voltage to a piezoelectric material, and this motion is typically converted into audible sound using diaphragms and resonators.
Piezoelectricity         
Piezoelectricity (, ) is the electric charge that accumulates in certain solid materials—such as crystals, certain ceramics, and biological matter such as bone, DNA, and various proteins—in response to applied mechanical stress. The word piezoelectricity means electricity resulting from pressure and latent heat.

Piezoelectricity

Piezoelectricity (, US: ) is the electric charge that accumulates in certain solid materials—such as crystals, certain ceramics, and biological matter such as bone, DNA, and various proteins—in response to applied mechanical stress. The word piezoelectricity means electricity resulting from pressure and latent heat. It is derived from Ancient Greek πιέζω (piézō) 'to squeeze or press', and ἤλεκτρον (ḗlektron) 'amber' (an ancient source of electric current).

The piezoelectric effect results from the linear electromechanical interaction between the mechanical and electrical states in crystalline materials with no inversion symmetry. The piezoelectric effect is a reversible process: materials exhibiting the piezoelectric effect also exhibit the reverse piezoelectric effect, the internal generation of a mechanical strain resulting from an applied electric field. For example, lead zirconate titanate crystals will generate measurable piezoelectricity when their static structure is deformed by about 0.1% of the original dimension. Conversely, those same crystals will change about 0.1% of their static dimension when an external electric field is applied. The inverse piezoelectric effect is used in the production of ultrasound waves.

French physicists Jacques and Pierre Curie discovered piezoelectricity in 1880. The piezoelectric effect has been exploited in many useful applications, including the production and detection of sound, piezoelectric inkjet printing, generation of high voltage electricity, as a clock generator in electronic devices, in microbalances, to drive an ultrasonic nozzle, and in ultrafine focusing of optical assemblies. It forms the basis for scanning probe microscopes that resolve images at the scale of atoms. It is used in the pickups of some electronically amplified guitars and as triggers in most modern electronic drums. The piezoelectric effect also finds everyday uses, such as generating sparks to ignite gas cooking and heating devices, torches, and cigarette lighters.

1. Discovered in 1880, piezoelectric crystals, emit a charge when subjected to sudden mechanical stress.
2. Solid state memory removes the need to spin hard drives at high speeds, points out Simon Powell, managing director of piezoelectric lock company Servocell.
3. The piezoelectric effect has subsequently been used in electronic equipment, clocks and watches, cigarette lighters, and many other items – including the "needles" of vinyl record players, which generate electricity as the groove moves them.
4. Dr Markys Cain, who runs the Sensor Knowledge Transfer Network at the National Physics Laboratory, hopes to see fabric that generates its own power using piezoelectric fibres woven into frequently moving joints such as elbows and knees.
5. "You could have applied energy harvesting devices within those dampers." Servocell‘s Powell, a former Cambridge lecturer and patent holder in several piezoelectric applications, agrees: "If you had piezos on that, you could probably have lit it with LEDs," he says.
