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, development of opposite electrical charges on different parts of a crystal that is subjected to temperature change.

Pyroelectricity is defined as the generation of surface charges in polar materials that is proportional to temperature changes (ΔT), enabling the direct production of an electric signal in pyroelectric sensors.

Aug 1, 2005 · Pyroelectricity is a coupled effect that relates a change in temperature to a change in electrical displacement D (with units of C/M 2 ), 𝑑 𝐷 = p 𝑑 𝜃, where p is the pyroelectric coefficient (with …

This review intends to address the concept, figures of merit of pyroelectricity, and recent progress in pyroelectric materials, such as ferroelectrics and relaxor ferroelectrics, efficient methods to harvest …

Pyroelectricity refers to the property of certain crystals and ceramics which are naturally electrically polarized and, therefore, contain large electric fields.

This page explores pyroelectricity in crystalline materials, detailing the conversion of temperature differences into electricity via polarization changes. It differentiates pyroelectric and …
