A study is conducted to report the first example of exploiting the electrocaloric effect (ECE) of nanostructured ferroelectric materials for personal cooling applications. ECE, an electric field induced temperature and entropy changes of a dielectric material, provides an energy-efficient and environmentally friendly means to realize solid-state cooling devices. Colossal ECE in terms of isothermal cooling energy density, adiabatic temperature change. and isothermal entropy change has been achieved in a variety of ferroelectric materials including single crystals, bulk ceramics, ceramic thin films, and polymers.
