“…The change in bending characteristic based on the different thickness has been reported in the literature [6]. It was concluded that at the same electric field the thicker film can bend greater and nearly proportional to the electric field at the same time.…”

We are investigating a polymer soft actuator using a poly urethane elastomer film that bends by an applied voltage, which is based on the electrostriction. In this article, the bending magnitude was studied in a weight-loaded condition. It was found that the thinner film can bend the more without any load, but that the film of 200-μm thickness gave the largest bending when weights were loaded. The thickness of some degree is critical for large bending torque.

“…The displacement was about 7 mm at most. It is supposed to bend more if the film thickness is less than 400 μm [6]. It is because the electric field induced in the film is inversely proportional to the film thickness.…”

A polymer soft actuator is under investigation using a poly urethane elastomer film that bends by means of an applied voltage, which is based on the electrostriction. Bending experiments were performed under different metal electrodes deposited the both sides of the film. Even if the thickness of the both electrodes is the same, the metal of the both electrodes is desirable to be the same to bend more. It is suggested that the balance of the physical properties of the both metal is critical for larger bending.
