  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. 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'.

  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 motor - Wikipedia

    en.wikipedia.org/wiki/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. An electrical circuit makes acoustic or ultrasonic ...

  6. Piezo ignition - Wikipedia

    en.wikipedia.org/wiki/Piezo_ignition

    Piezo ignition uses the principle of piezoelectricity, which, in short, is the electric charge that accumulates in some materials in response to mechanical deformation. It consists of a small, spring-loaded hammer which, when a button is pressed, hits a crystal of PZT. This sudden forceful deformation produces a high voltage and subsequent ...

  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. Piezotronics - Wikipedia

    en.wikipedia.org/wiki/Piezotronics

    Working mechanism for piezoelectric devices with one end of the piezoelectric material is fixed. The induced piezopotential distribution is similar to the applied gate voltage in a traditional field-effect transistor, as shown in (b). Schematic diagram showing the three-way coupling among piezoelectricity, photoexcitation and semiconductor.
