| Abstract Scope |
Phase-changing materials with large caloric effects have the promise of realizing solid-state refrigeration, which is more efficient and environmentally friendly than current techniques [1]. A review of recent direct measurements of the large electrocaloric effect in liquid crystalline materials and the large elastocaloric effect in liquid crystal elastomers will be given [2,3].. Direct measurements indicate that the large elastocaloric response with giant elastocaloric responsivity can be found in main-chain liquid crystalline elastomers. Both soft materials can play a significant role as active cooling elements and parts of thermal diodes or regeneration materials in developing new cooling devices. [1] Z. Kutnjak, B. Rozic, and R.
