The Electrocaloric Effect: Materials and Applications reviews the fundamentals of the electrocaloric effect, the most relevant electrocaloric materials, and electrocaloric measurements and device applications. The book introduces the electrocaloric effect along with modelling and simulations of this effect. Then it addresses the latest advances in synthesis, characterization, and optimization of the most relevant electrocaloric materials including ferroelectric materials, liquid materials, lead-free materials, polymers, and composites. Finally, there is a review of the latest techniques in measurement and applications in refrigeration and cooling. The advantages, challenges, and perspectives of the future of electrocaloric refrigeration are discussed. The Electrocaloric Effect is suitable for researchers and engineers in the disciplines of materials science, engineering, and physics.
