In this study, electrocaloric effects of Pb-free (Ba0.85Ca0.15)(Ti0.92Zr0.08)O3 ferroelectric ceramics were investigated and discussed using the characteristics of P-E hysteresis loops at wide temperature range from room temperature to 140℃. The remnant polarization Pr and coercive field Ec were decreased with increasing temperature. The temperature change ΔT by the electrcaloric effect was calculated by Maxwell`s relations, and reached the maximum of ∼0.15 at 120℃ under applied electric field of 30 kV/㎝.
