Abstract

An electrocaloric module includes an electrocaloric element that includes an electrocaloric film, a first electrode on a first surface of the electrocaloric film, and a second electrode on a second surface of the electrocaloric film. A support is attached along an edge portion of the electrocaloric film, leaving a central portion of the electrocaloric film unsupported film. At least one of the first and second electrodes includes a patterned disposition of conductive material on the film surface. The electrocaloric module also includes a first thermal connection configured to connect to a first thermal flow path between the electrocaloric element and a heat sink, a second thermal connection configured to connect to a second thermal flow path between the electrocaloric element and a heat source, and a power connection connected to the first and second electrodes and configured to connect to a power source.
