Pyroelectricity refers to electric charge generation mechanisms along specific crystallographic directions driven by changes in crystal temperature [2].

It exhibits unique properties, such as pyroelectricity and piezoelectricity.
The technology is based on the concept of pyroelectricity, in which certain materials can generate a temporary voltage when they are heated or cooled.
Topics include: dielectricity, piezoelectricity, pyroelectricity, and ferroelectricity; a structural approach to thermodynamic study; ferroelectric-paraelectric phase transition thermodynamic modeling; formalism; electric characterization, piezoelectric resonators and filters; high overtone bulk acoustic resonators; electrostrictive resonators, and thin film piezoelectric transducers.
The possible role of Dauphine twinning and the probable role of pyroelectricity both are central in one line of thought (see later), but no settled agreement about exactly how gwindels form has yet been reached.
He focuses on tensors, matrices, symmetry and the relationships between structure and property, including transformation, thermodynamic relationships, pyroelectricity, stress and strain, elasticity, magnetic and nonlinear phenomena, ferrole crystals, electric resistance, acoustic waves, optics (including nonlinear optics), dispersion and absorption and chemical anisotropy.
Incidentally, ferroelectrics also have the property of piezoelectricity (stress induced polarization) and pyroelectricity (temperature induced polarization), but those properties are not important to this discussion.

This tetrahedron configuration is responsible for the piezoelectricity and pyroelectricity [14, 15].
When considering the detection of infrared radiation (IR) with pure and doped Polyvinylidene difluoride (PVDF film), using the mechanism of pyroelectricity, considerable research has been conducted.
