The electrocaloric effect (ECE) is investigated in a dielectric liquid. By exploiting the large dielectric anisotropy in a liquid crystal, 5CB, that facilitates the electric-field-induced large polarization change, a large ECE is observed near 39 °C, the nematic-isotropic transition temperature region. Fluidic ECE materials could lead to easier and better design of ECE-based cooling devices.
