Abstract
It was found that the bending curvature and generated force of largely dehydrated Selemion sandwiched between thin silver layers came to have a definite correlation to the quantity of charge given to it. Both curvature and force have almost linear relationship to the charge quantity. It was interpreted as the control of charge would result in the control of curvature and force, which are the essential characteristics for the actuator. In fact, we could observe the precise controllability of curvature and force of Selemion by the control of charge quantity given to Selemion.
