Pyroelectricity (from Greek: pyr (πυρ), "fire" and electricity) is a property of certain crystals which are naturally electrically polarized and as a result contain large electric fields. [1] Pyroelectricity can be described as the ability of certain materials to generate a temporary voltage when they are heated or cooled.
The process of pyroelectricity has been known from ancient times. [6] The first use of a pyroelectric field to accelerate deuterons was in a 1997 experiment conducted by Drs. V.D. Dougar Jabon, G.V. Fedorovich, and N.V. Samsonenko. [7] This group was the first to utilize a lithium tantalate (LiTaO 3) pyroelectric crystal in fusion experiments.
Ferroelectricity is a subset of pyroelectricity, which brings spontaneous electronic polarization to the material. [23] 32 Crystalline classes; 21 noncentrosymmetric
Photopyroelectric As known that Photopyroelectric can be regarded as –Photo +Pyroelectric，which means any optical systems using a pyroelectric detector or imaging system, In addition, pyroelectricity could be depicted as the capability of the components formulating the transient voltage when heated or cooled.
The Ericsson cycle is analogous to the Olsen cycle.. The Olsen cycle is a pyroelectric cycle, which was developed between 1978 and 1986 by Olsen and Bruno, [1] by Olsen and Brown, [2] Olsen and Evans, [3] as well as by Olsen et al. [4] It has been called the Ericsson cycle.
