Thermal Energy Harvesting using BaTiO3 Based Ferroelectric Ceramics: A Review

Abstract

Ferroelectric oxide ceramics are used in a very broad range of functional ceramics and form the materials base for the majority of electronic applications like sensors, actuators, buzzers, medical ultrasonic transducers, etc. These materials have excellent piezoelectric properties, pyroelectric properties, figure of merits (FOMs) and good temperature stability. In this context, efficient conversion of heat energy into electric signal is of great importance. Pyroelectric materials have been extensively explored for such kind of energy harvesting applications. These materials generate electrical current on the expense of input thermal energy. This property of these materials propounds ample possibilities for harnessing energy from the thermal by-products of many ferroelectric materials are also promising for efficient energy storage capacity (ESD).This study explore the knowledge about the energy storage density and thermal energy harvesting potential for Sn doped BaTiO3 based ferroelectric material. Therefore, we can get the maximum energy storage density and maximum energy harvesting density materials.
