    We have developed an actuator consisting of an ionic liquid gel electrolyte sandwiched between two nanofiber mat electrodes. The electrodes were fabricated by an electro-spinning technique followed by the vapor phase polymerization of poly(3,4-ethylenedioxythiophene) (PEDOT). The strain induced by the actuator sharply increased when the polymerization time of the electrode was more than 6 min. This actuator exhibited partial transparency, and could drive at very low voltage (1.5 V), comparing with the conventional dielectric actuators having transparency.
