Effective Pyroelectric Coefficient of Layered Structures

The paper encompasses the investigation of the effective pyroelectric behavior of materials in different structures/systems such as the bimorphs and the sandwiched structure, with the variation of the temperature. Different mathematical approaches have been used to include the secondary factors contributing to the effective pyroelectric coefficient, and it has been included to obtain a consolidated expression of the same. The effective pyroelectric coefficient for few selected ferroelectric materials has been deduced using their actual physical constants to get a closer resemblance with the practical device. This paper would be a step forward to the fabrication of layered material with a higher pyroelectric coefficient for a possible energy harvesting applications also.
