Abstract
Thermal transfer devices according to the present invention comprise electrocaloric materials that increase in temperature upon application of an applied voltage thereto and decrease in temperature upon removal of the applied voltage. In specific embodiments of the present invention, the electrocaloric materials, described in further detail below, are configured such that the respective increases and decreases in temperature of the electrocaloric material extend from about -10.degree. C. to about 50.degree. C. As a result, thermal transfer devices according to the present invention are suitable for use in a wide variety of practical refrigeration applications. In accordance with 37 CFR 1.72(b), the purpose of this abstract is to enable the United States Patent and Trademark Office and the public generally to determine quickly from a cursory inspection the nature and gist of the technical disclosure.
