Abstract: The present disclosure is drawn to electrocaloric devices, methods of making electrocaloric integrated circuits, and methods of thermally cycling integrated circuits. The electrocaloric device can include an electrocaloric material having a solid solution of two or more components of BNT, BKT, BZT, BMgT, or BNiT. The electrocaloric material can have an ergodic transition temperature within a range of 50 C to 300 C. The device can also include electrodes associated with the electrocaloric material, as well as an electrical source to add or reduce electrical field between the electrodes across the electrocaloric material to generate heating or cooling relative to the ergodic transition temperature of the electrocaloric material.
