Abstract
Electrocaloric effect (ECE), i.e., the heating or cooling of electrocaloric material due to the applied electric field under adiabatic conditions, is very attractive phenomenon for application in cooling and heating devices of new generation in which heating and cooling elements will be made without moving parts and they would be energetically more efficient and friendlier for environment. The first observations of the giant ECE were made by indirect measurements of the electric polarization. In our case we investigated the electrocaloric effect by direct measurements. Here we present results of the temperature change ΔTEC in a relaxor ferroelectric terpolymer P(VDF-TrFE-CFE) near the room temperature.
