Outline of Seeds

Recent innovations of polymer actuators reveal their advantages such as softness, light weight, or silent motion. The goal of our research is practical applications using polymer actuators. The polymer actuators employed in our research are ionic polymers, dielectric elastomer, and fishing-line artificial muscle. Typical examples of the applications include wearable robotics for assistance or rehabilitation, light-weight muscle-driven robot, and novel mechanism for mechatronics devices.
