Paper Abstract

The essential motion of the ionic polymer-metal composite (IPMC) is bending, therefore some mechanisms are expected to transform from the bending to other required motions. Motivated by the motion of a spiral spring, we discovered that the bending of the ionic polymer could be directly transformed to the limited angle rotation. We introduce the model of the rotary actuator, which consists of mechanical, electrical and electromechanical dynamics. The motion of the rotary actuator is demonstrated in the experiment. The stationary properties are measured and the parameters of the dynamical model are identified, which are also validated by experiments.
