Electrocaloric cooling devices traditionally comprise sub-millimetre-thick ceramic working bodies surrounded by relatively massive apparatus. Now, cooling devices that are each based on a thin polymer layer have been stacked to yield a composite lightweight device that pumps heat across a wide temperature span.

传统上，电热冷却装置包括由相对较大的设备围绕的亚毫米厚的陶瓷工作体。现在，已经堆叠了各自基于薄聚合物层的冷却装置，以生产出一种复合轻质装置，该装置可在较宽的温度范围内泵送热量。
