电驱动的温度绝热变化的原型电热材料PbSc 0.5Ta 0.5O3通过比较的等温变化的电极化由于电场的缓慢变化和绝热变化的电极化由于电场的快速变化。通过在测量（起始）温度下获得等温（绝热）电极化数据，
Electrically driven adiabatic changes of temperature are identified in the archetypal electrocaloric material PbSc0.5Ta0.5O3 by comparing isothermal changes of electrical polarization due to the slow variation of electric field and adiabatic changes of electrical polarization due to the fast variation of electric field. By obtaining isothermal (adiabatic) electrical polarization data at measurement (starting) temperatures separated by
