Abstract: The mutual influence of an external electric field and mechanical stresses on the electrocaloric effect has been studied. Under certain conditions, the varying external field produces parametric enhancement of the electrocaloric effect. Using this phenomenon, it is possible to realize the Carnot cycle in ferroelectric energy converters and solid-state coolers.
