    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. Smart material - Wikipedia

    en.wikipedia.org/wiki/Smart_material

    There are a number of types of smart material, of which are already common. Some examples are as following: Piezoelectric materials are materials that produce a voltage when stress is applied. Since this effect also applies in a reverse manner, a voltage across the sample will produce stress within sample.

  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. 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.

  8. Pyroelectricity - Wikipedia

    en.wikipedia.org/wiki/Pyroelectricity

    The piezoelectric effect is exhibited by crystals (such as quartz or ceramic) for which an electric voltage across the material appears when pressure is applied. Similar to pyroelectric effect, the phenomenon is due to the asymmetric structure of the crystals that allows ions to move more easily along one axis than the others.

  9. 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 ...
