Beschreibung
Zusammenfassung:	An electrocaloric device based on a liquid material suitable for cooling and heat management. The liquid crystalline material designated for the device is operated in or in vicinity of the ferroelectric nematic phase. The device has broad operating temperature, high induced temperature change, while requiring modest electric field strengths. L'invention concerne un dispositif électrocalorique basé sur un matériau liquide approprié pour le refroidissement et la gestion de chaleur. Le matériau cristallin liquide désigné pour le dispositif est actionné dans ou à proximité de la phase nématique ferroélectrique. Le dispositif présente une large température de fonctionnement, un changement de température induit élevé, tout en nécessitant des intensités de champ électrique modestes.
