Recently, with the development of human-interactive soft electronic devices, i-EAP actuators are being spotlighted as a candidate for soft actuator of haptic feedbacks because they have the advantages such as lightweight, flexibility, and low driving voltage. Particularly, I-EAP actuators for haptic feedback are required to high blocking force and wide actuation bandwidth. However, i-EAP actuators for haptic feedback are still lacking. In this talk, we propose an ionic soft actuator with high blocking force and wide actuation bandwidth based on PEDOT:PSS. In to improve actuation performance, we induced diffusion interface between electrodes and an ionic polymer using spray coating with DMSO and IL as an additive, and electrical conductivity of PEDOT:PSS electrodes was also increased. As a result, we successfully developed an ionic soft actuator that operates stably up to a frequency of 200 Hz. Also, our actuator showed blocking forces improvement of 0.4mN. |
