Abstract
The electrocaloric effect (ECE) is the entropy and temperature change of a dielectric when subject to a change of electric field. This chapter will discuss briefly thermodynamic considerations for materials that exhibit large ECE and review previous results of the ECE in polar crystals, ceramics, and thin films. ECE results from direct measurement and deduced from Maxwell's relations will be presented along with the phenomenological modeling for ferroelectric polymers, which have been recently discovered to exhibit a large ECE. Finally the ECE of polar materials are modeled to forecast their potential in future devices.
