Efficiency is defined as η = | Q |/| W | in order to investigate the electrical work | W | associated with electrocaloric heat | Q | . This materials parameter indicates that polymer films are slightly more energy efficient than ceramic films, and therefore both species of material remain candidates for future cooling applications.
