  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. Radioisotope piezoelectric generator - Wikipedia

    en.wikipedia.org/wiki/Radioisotope_piezoelectric...

    A radioisotope piezoelectric generator ( RPG) is a type of radioisotope generator that converts energy stored in radioactive materials into motion, which is used to generate electricity using the repeated deformation of a piezoelectric material. This approach creates a high-impedance source and, unlike chemical batteries, the devices will work ...

  4. Nanogenerator - Wikipedia

    en.wikipedia.org/wiki/Nanogenerator

    A schematic view of a typical Nanocomposite Electrical Generator NEG is a 3-dimensional configuration consisting of three main parts: the metal plate electrodes, the vertically grown piezoelectric nanostructure, and the polymer matrix, which fills in between the piezoelectric nanostructure.

  5. Piezoelectric sensor - Wikipedia

    en.wikipedia.org/wiki/Piezoelectric_sensor

    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 ...

  6. Piezoelectric motor - Wikipedia

    en.wikipedia.org/wiki/Piezoelectric_motor

    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. An electrical circuit makes acoustic or ultrasonic vibrations in the piezoelectric material, most often lead zirconate titanate and ...

  7. Piezoelectric accelerometer - Wikipedia

    en.wikipedia.org/wiki/Piezoelectric_accelerometer

    A piezoelectric accelerometer is an accelerometer that employs the piezoelectric effect of certain materials to measure dynamic changes in mechanical variables (e.g., acceleration, vibration, and mechanical shock). As with all transducers, piezoelectrics convert one form of energy into another and provide an electrical signal in response to a ...

  8. Pierce oscillator - Wikipedia

    en.wikipedia.org/wiki/Pierce_oscillator

    The Pierce oscillator is a type of electronic oscillator particularly well-suited for use in piezoelectric crystal oscillator circuits. Named for its inventor, George W. Pierce (1872–1956), [1][2] the Pierce oscillator is a derivative of the Colpitts oscillator. Virtually all digital IC clock oscillators are of Pierce type, as the circuit can ...

  9. List of piezoelectric materials - Wikipedia

    en.wikipedia.org/wiki/List_of_piezoelectric...

    Piezoelectric materials (PMs) can be broadly classified as either crystalline, ceramic, or polymeric. [1] The most commonly produced piezoelectric ceramics are lead zirconate titanate (PZT), barium titanate, and lead titanate. Gallium nitride and zinc oxide can also be regarded as a ceramic due to their relatively wide band gaps.
