(piezoelectricity)
31Ferroelectricity — is a property of certain materials which possess a spontaneous electric polarization that can be reversed by the application of an external electric field.[1][2] The term is used in analogy to ferromagnetism, in which a material exhibits a… …
32Pyroelectricity — is the ability of certain materials to generate an electrical potential when they are heated or cooled. As a result of this change in temperature, positive and negative charges move to opposite ends through migration (i.e., the material becomes… …
