In this paper, we investigated the Electrothermal conversion of ferroelectric materials. The key parameters foe cooling and energy scavenging were identified.In the frameworf of pyroelectric energy harvesting, first results using SSD technique showed a magnification of the voltage by a factor of 2. We believed that the use to films could increase the power by a factor of 10 - 100, Currents works with PVDF films is being held in the laboratory.In the framework of electrocaloric refrigeration, we believed that ultrahigh efficiency cooling devices may be designed. However, the main limitation now is the maximal temperature of 1-2K. controllable by the electric field. Further work with small thicknesses (fibres, thin and thick films) could be interesting due to the very highpossible electric fields.
