    摘要: 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.

    摘要: A method of making an electrocaloric element includes providing an electrocaloric material, forming a first electrode at a first surface of the electrocaloric material, and forming a second electrode at a second surface of the electrocaloric material. The forming of the first electrode includes, or the forming of the second electrode includes, or the forming of each of the first and second electrodes independently includes modifying the respective first and/or second surface of the electrocaloric material with an electrically conductive surface modification.
