Abstract:
A method of making an electrocaloric article is disclosed in which a continuous sheet of an electrocaloric film is bent back and forth to form a plurality of connected aligned segments of electrocaloric film with gaps between film surfaces of adjacent aligned segments. The continuous sheet of electrocaloric film is secured in this with a securing method that includes attaching a spacer to the continuous sheet of electrocaloric film prior to the back and forth bending; or providing a spacer comprising a base and a plurality of projections extending from the base, and inserting the projections into the gaps between the film surfaces of adjacent aligned segments after the back and forth bending; or interweaving a continuous spacer through the gaps between the aligned segments of the electrocaloric film; or attaching an end cap to a plurality of connecting portions of the electrocaloric film between the aligned segments.
