RT Journal Article SR Electronic T1 Caloric materials for cooling and heating JF Science JO Science FD American Association for the Advancement of Science SP 797 OP 803 DO 10.1126/science.abb0973 VO 370 IS 6518 A1 Moya, X. A1 Mathur, N. D. YR 2020 UL http://science.sciencemag.org/content/370/6518/797.abstract AB Magnetically driven thermal changes in magnetocaloric materials have, for several decades, been exploited to pump heat near room temperature. By contrast, their electrocaloric and mechanocaloric counterparts have only been intensively studied and exploited for little more than a decade. These different caloric strands have recently been unified to yield a single field of research that could help combat climate change by generating better heat pumps for both cooling and heating. Here we outline the timeliness of the present activity and discuss recent advances in caloric measurements, materials, and prototypes.
