Development of Next Generation Medical Robotics Soft Actuators

Ion polymer metal compound is a conductive polymer chemically plated with precious metal such as gold or platinum. It works both as an actuator and sensor. As an actuator, it works with relatively low voltage of 1-3 V, generates large displacement, deformable to any shape, and with no noise. It is one of the most ideal actuator material for artificial muscle. We have succeeded to develop a prototype artificial tongue as well as artificial vocal cord. Further, we have developed a smart interactive textile that continuously monitors the displacement angle of human motion using ion polymer metal compound as a sensor.
