  A contactless technique for direct time-resolved measurements of the full
dynamics of the adiabatic temperature change in electrocaloric materials is
introduced. The infrared radiation emitted by the electrocaloric sample is
sensitively detected with $\mu$s time resolution and mK temperature resolution.
We present time-resolved measurements of the electrocaloric effect up to kHz
frequencies of the driving electric field and down to small field strengths.
The simultaneous recording of transients for applied electric field and induced
polarization gives a comprehensive view on the correlation of electrocaloric
and ferroelectric properties. The technique can further be applied to the
continuous measurement of fatigue for $> 10^6$ electric field cycles.
