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.

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 ...
