Experimental setup used to characterize the electrocaloric cooling cycle.
Characterization of a stand-alone multilayer capacitor: (a) hysteresis loop at room temperature (b) temporal temperature profile upon application and removal of a bias field of magnitude 300 kV/cm.
The experimentally measured (a)and numerically simulated (b) temporal temperature profile of the heater under the initial steady state, under the mechanical oscillation only, and under the electrocaloric cooling conditions. The cycle frequency is fixed at 0.12 Hz.
(a) The predicted and measured cycle averaged temperatures under the two steady periodic conditions and (b)their difference as a function of cycling frequency.
