[14p-421-6] Electrocaloric Effects and Temperature Distribution Analysis of BaTiO3-based Ceramics and Multi-layer Capacitor

〇Hiroshi Maiwa1, Yuki Oba1 (1.Shonan Inst. Tech.)

Keywords:ferroelectroics, electrocaloric effect

The electrocaloric temperature change, deltaT, due to applied deltaE, of the BaTiO3-based ceramics is estimated and directly measured. Temperature-electric field (T-E) loops of the Ba(Zr,Ti)O3 ceramics and BaTiO3-based multi-layer capacitor are mesured. The comparison with the estimations from indirect approach based on Maxwell’s equation will be discussed. And temperature distribution analysis of the BaTiO3-based multi-layer capacitor will be discussed for the realization of the cooling devices.
