Upon the invitation from Nature Materials, Mojca Otoničar from Electronic Ceramics Department, JSI, and Brahim Dkhil from CentraleSupelec, University of Paris-Saclay, wrote an opinion for News&Views - Electrocalorics hit the top (published October 24, 2019). They commented on an article published in Nature (published online October 9, 2019), in which a team of researchers led by Xavier Moya and Neil Mathur from the University of Cambridge reported on multilayer capacitors exhibiting an extremely high electrocaloric effect (∆T=5.5K), forecasting a breakthrough of the alternative cooling technology. The authors demonstrated the importance of active material to be pushed into a 'supercritical' state by an electric field, yielding a strongly enhanced electrocaloric response.
