pyroelectric (rus. пироэлектрик) — a dielectric material with ability to generate electric charges on the surface when it is heated or cooled.


Intensity of electrisation depends on the temperature change rate.

Generation of charges on the surface of a pyroelectric material occurs due to a change in spontaneous polarisation within the pyroelectric caused by a change in crystal temperature.
