Zusammenfassung:Flexible lead‐free ferroelectric ceramic nanowire arrays exhibit a unique combination of features that can contribute to the realization of wearable cooling devices, including an outstanding electrocaloric effect at low fields, high efficiency, bendability and stretchability, and robustness against mechanical deformations. Thermodynamic and phase‐field simulations are carried out to validate their superior electrocaloric effect in comparison to thin films.
