Abstract
A haptic actuator using a cellulose electro-active paper film is provided. The haptic actuator includes a cellulose electro-active paper film exhibiting a piezoelectric phenomenon and a metal electrode for applying electricity to the electro-active paper film, so that the haptic actuator can be provided in the form of a thin film, can manifest high transparency, and can produce displacement to the magnitude of sufficiently stimulating the sensor receptors of a user's skin in response to the applied electricity. Also, the haptic actuator is friendly to the environment and humans thanks to the use of cellulose which is an environmentally friendly material.
