Cold sensation actuator using electrocaloric effect and cold sensation actuating method using electrocaloric effect

摘要

The present invention relates to a driver providing a feeling of cold using an electrothermal effect (Electrocaloric Effect), providing a feeling of cold using the deformation characteristics of the piezoelectric body and an electrothermal effect (Electrocaloric Effect), through controlling the voltage applied to the electrodes By providing cold feeling by rapid temperature change, it is possible to realize miniaturized and slim products, which can be applied to all products requiring haptic function improvement, and adds haptic sensation when using electronic devices to reduce the feeling of reality. It allows us to expect the benefits of being able to.
