Electric card effect tester

DK0510 electric card effect tester is a measurement system specifically designed to test the surface temperature changes of materials under high voltage. By adding changes in the electric field value on the surface of the material, the temperature value of the material can be detected. This system consists of a high-voltage system and a temperature data acquisition system, and is suitable for measuring materials such as ceramics.

The electrocaloric effect is a change in adiabatic temperature or isothermal entropy that occurs in polar materials due to a change in the polarization state caused by an external electric field [1-3]. Due to the direct correlation between the electric card effect and changes in polarization intensity, ferroelectric materials with strong polarity can produce significant electric card effects. Applying an electric field to polar materials causes the electric dipoles in the material to change from disorder to order, resulting in a decrease in entropy. Under adiabatic conditions, the excess entropy leads to an increase in temperature. Removing the electric field causes the electric dipoles in the material to change from ordered to disordered, increasing the entropy of the material. Under isothermal conditions, the material absorbs heat from the outside and conserves energy.
