Wearable Devices: Toward Wearable Cooling Devices: Highly Flexible Electrocaloric Ba_0.67Sr_0.33TiO₃ Nanowire Arrays (Adv. Mater. 24/2016)

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.
