On page 4811, Q. Wang, and co‐workers describe ferro‐electric ceramic nanowire arrays, which exhibit a high electrocaloric effect under low applied electric fields. The prepared lead‐free ceramic nanostructured array is highly bendable and stretchable, and retains its excellent electrocaloric response in rigorous mechanical‐deformation tests. These superior electrocaloric properties, in comparison to thin films, are validated using thermodynamic and phase‐field simulations.
