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

    The piezoelectric coefficients (d 33, d 31, d 15 etc.) measure the strain induced by an applied voltage (expressed as meters per volt). High d ij coefficients indicate larger displacements which are needed for motoring transducer devices.

  3. 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 ...

  4. Piezoelectric coefficient - Wikipedia

    en.wikipedia.org/wiki/Piezoelectric_coefficient

    The piezoelectric coefficient or piezoelectric modulus, usually written d 33, quantifies the volume change when a piezoelectric material is subject to an electric field, or the polarization on the application of stress.

  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. Piezoresponse force microscopy - Wikipedia

    en.wikipedia.org/wiki/Piezoresponse_force_microscopy

    Take as an example, the d 33 piezoelectric tensor coefficient of BaTiO 3, it has a value of 85.6 pm V −1 meaning that applying 1 V across the material results in a displacement of 85.6 pm or 0.0856 nm, a minute cantilever displacement even for the high precision of AFM deflection detection. In order to separate this low level signal from ...

  7. Integrated Electronics Piezo-Electric - Wikipedia

    en.wikipedia.org/wiki/Integrated_Electronics...

    Integrated Electronics Piezo-Electric (IEPE) characterises a technical standard for piezoelectric sensors which contain built-in impedance conversion electronics. IEPE sensors are used to measure acceleration, force or pressure. Measurement microphones also apply the IEPE standard. Other proprietary names for the same principle are ICP, CCLD ...

  8. J-integral - Wikipedia

    en.wikipedia.org/wiki/J-integral

    The J-integral represents a way to calculate the strain energy release rate, or work per unit fracture surface area, in a material. [1] The theoretical concept of J-integral was developed in 1967 by G. P. Cherepanov [2] and independently in 1968 by James R. Rice, [3] who showed that an energetic contour path integral (called J) was independent of the path around a crack.

    The Smith chart (sometimes also called Smith diagram, Mizuhashi chart (水橋チャート), Mizuhashi–Smith chart (水橋スミスチャート), [1] [2] [3] Volpert–Smith chart (Диаграмма Вольперта—Смита) [4] [5] or Mizuhashi–Volpert–Smith chart) is a graphical calculator or nomogram designed for electrical and electronics engineers specializing in radio ...
