  2. Piezoelectricity - Wikipedia

    en.wikipedia.org/wiki/Piezoelectricity

    Piezoelectric balance presented by Pierre Curie to Lord Kelvin, Hunterian Museum, Glasgow. Piezoelectricity (/ ˌ p iː z oʊ-, ˌ p iː t s oʊ-, p aɪ ˌ iː z oʊ-/, US: / p i ˌ eɪ z oʊ-, p i ˌ eɪ t s oʊ-/) [1] 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 ...

  3. Vibration-powered generator - Wikipedia

    en.wikipedia.org/wiki/Vibration-powered_generator

    The ability to make piezoelectric generators on such a small scale is the main advantage of this method over the electromagnetic generators, especially when the generator is being developed to power microelectronic devices. Piezoelectric vibration generator has been commercialized.

  4. Piezotronics - Wikipedia

    en.wikipedia.org/wiki/Piezotronics

    Working mechanism for piezotronic devices with two ends fixed with electrodes on a flexible substrate. This asymmetric tuning of the Schottky barrier height is the piezotronic effect. Piezotronics effect is using the piezoelectric potential (piezopotential) created in materials with piezoelectricity as a “gate” voltage to tune/control the ...

  5. Piezoelectric sensor - Wikipedia

    en.wikipedia.org/wiki/Piezoelectric_sensor

    A piezoelectric disk generates a voltage when deformed (change in shape is greatly exaggerated) A piezoelectric sensor is a device that uses the piezoelectric effect to measure changes in pressure, acceleration, temperature, strain, or force by converting them to an electrical charge. The prefix piezo-is Greek for 'press' or 'squeeze'. [1]

  6. Piezoelectric motor - Wikipedia

    en.wikipedia.org/wiki/Piezoelectric_motor

    Insides of a slip-stick piezoelectric motor. Two piezoelectric crystals are visible that provide the mechanical torque. [1]A piezoelectric motor or piezo motor is a type of electric motor based on the change in shape of a piezoelectric material when an electric field is applied, as a consequence of the converse piezoelectric effect.

  7. Piezoelectric microelectromechanical systems - Wikipedia

    en.wikipedia.org/wiki/Piezoelectric_micro...

    A piezoelectric microelectromechanical system (piezoMEMS) is a miniature or microscopic device that uses piezoelectricity to generate motion and carry out its tasks. It is a microelectromechanical system that takes advantage of an electrical potential that appears under mechanical stress .

  8. Nanogenerator - Wikipedia

    en.wikipedia.org/wiki/Nanogenerator

    A piezoelectric nanogenerator is an energy-harvesting device capable of converting external kinetic energy into electrical energy via action by a nano-structured piezoelectric material. It is generally used to indicate kinetic energy harvesting devices utilizing nano-scaled piezoelectric material, like in thin-film bulk acoustic resonators .

  9. Buzzer - Wikipedia

    en.wikipedia.org/wiki/Buzzer

    A buzzer or beeper is an audio signaling device, [1] which may be mechanical, electromechanical, or piezoelectric (piezo for short). Typical uses of buzzers and beepers include alarm devices, timers, train and confirmation of user input such as a mouse click or keystroke.
