Physics, Chemistry and Technology of Solid State Gas Sensor ...
Pyroelectricity: A 2300- Year History The phenomenon of pyroelectricity is not
new; it has some 2300 years of history. The first description of the pyroelectric
effect was published by the Greek philosopher Theophrastus (ca. 372-287 B.C.)
in his ...
High Quality Content by WIKIPEDIA articles! Pyroelectricity (from the Greek pyr, fire, and electricity) is the ability of certain materials to generate a temporary voltage when they are heated or cooled.
Jesse Russell, Ronald Cohn, 2012

The Beginnings of Piezoelectricity: A Study in Mundane Physics
Pyroelectricity As mentioned, Voigt assumed that like piezoelectricity,
pyroelectricity is due to innerdeformations in the crystals caused by
thermalexpansion. The Curies, R ̈ontgen, and Friedel had already advanced
the hypothesis that ...

The relation between ferroelectricity and pyroelectricity in the perovskites is explored using Devonshire's phenomenological theory of ferroelectricity and a new microscopic theory obtained by generalizing the conventional molecular field ...
M. I. Bell, P. M. Raccah, BELFER GRADUATE SCHOOL OF SCIENCE NEW YORK., 1975
Pyroelectricity. The pyroelectric effect is defined as the change in spontaneous
polarisation, Ps, as a function of temperature, T. The pyroelectric coefficient, p, is
mathematically defined as shown in equation 1.4. p1⁄4 dPs dT ð1:4Þ The ...
Duncan W. Bruce, Dermot O'Hare, Richard I. Walton, 2011
CONCLUSIONS AND SOME SPECULATIONS We have two major objectives in
this chapter: (1) to concisely summarize the physics of pyroelectricity and closely
related effects and describe the techniques for measuring them; and (2) to ...
