Two teams working independently of each other have demonstrated designs for electrocaloric cooling that can change temperatures under an electric field. Both groups used lead scandium tantalate capacitors in their systems, but they differed slightly in how they were used. The first group, with members from PARC in the U.S. and Murata Manufacturing Co., in Japan showed that electrocaloric cooling could be done using only solid materials. The second group, with members from the Luxembourg Institute of Science and Technology and Murata Manufacturing Co. in Japan used fluids for heat transfer. Both teams have published accounts of their work and findings in the journal Science.
