Electrocaloric Ceramics

Abstract

Electrocaloric effect (ECE) is a coupling between thermal and electrical phenomena, specifically it is the change in the entropy of a dielectric material as a result of an electrical stimulus. Electrocaloric materials are currently being investigated as a solid state refrigeration approach for on-chip cooling applications. Among the organic and inorganic electrocaloric material choices, electrocaloric ceramics are at the forefront with their higher electrocaloric coefficients. This article gives a background on the fundamentals of electrocalorics and then discusses the general trends in the literature on the electrocaloric ceramics research. © 2023 Elsevier B.V., All rights reserved.
