    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 ...

  5. Pyroelectricity - Wikipedia

    en.wikipedia.org/wiki/Pyroelectricity

    However, note that some piezoelectric materials have a crystal symmetry that does not allow pyroelectricity. Pyroelectric materials are mostly hard and crystals; however, soft pyroelectricity can be achieved by using electrets. [6] Pyroelectricity is measured as the change in net polarization (a vector) proportional to a change in temperature.

  6. Electroactive polymer - Wikipedia

    en.wikipedia.org/wiki/Electroactive_polymer

    The most common applications of this type of material are in actuators [1] and sensors. [2] [3] A typical characteristic property of an EAP is that they will undergo a large amount of deformation while sustaining large forces. The majority of historic actuators are made of ceramic piezoelectric materials. While these materials are able to ...

  7. Piezoelectric sensor - Wikipedia

    en.wikipedia.org/wiki/Piezoelectric_sensor

    These materials offer improved sensitivity over PZT but have a lower maximum operating temperature and are currently more complicated to manufacture due to four compound vs. three compound material PZT. Thin film piezoelectric materials can be manufactured utilizing sputtering, CVD (chemical vapour deposition), ALD (atomic layer epitaxy) etc ...

  8. Lead zirconate titanate - Wikipedia

    en.wikipedia.org/wiki/Lead_zirconate_titanate

    In general, soft lead zirconate titanate has a higher piezoelectric constant, but larger losses in the material due to internal friction. In hard lead zirconate titanate, domain wall motion is pinned by the impurities, thereby lowering the losses in the material, but at the expense of a reduced piezoelectric constant.

  9. Thin-film bulk acoustic resonator - Wikipedia

    en.wikipedia.org/wiki/Thin-film_bulk_acoustic...

    Any material like lead zirconate titanate (PZT) [7] or barium strontium titanate (BST) [8] from the list of piezoelectric materials could act as an active material in an FBAR. However two compound materials aluminium nitride (AlN) and zinc oxide (ZnO) are the two most studied piezoelectric materials manufactured for high frequency FBAR ...
