Abstract: This invention relates to a novel fabrication process of multi degree of freedom shaped EAPs actuation capability. For example, to achieve the multi-DOF actuation, the surface electrode layer of the rod-shaped IPMC should be inter-digitated to have multiple electrically insulated sections.

Abstract: New polymeric materials and their fabrication methods that are electrically active in terms of sensing and actuation are invented. These materials are comprised of solid-state ion-conducting materials such as polyethylene oxide (PEO) and its derivatives or imbedded in a family of mixed polymer systems such as polydivinylbenzene (DVB) and polystyrene polymers. Such materials suitably electroded with conductive materials such as gold, platinum and silver exhibit large deformation (both two and three dimensionally) under low electric fields of 10's V/mm. Conversely, if these materials are deformed, they produce 10's of mV/mm electric fields that can be used as means of sensing or electromechanical powering devices for batteries. The method of fabricating the new polymeric materials comprises the steps of providing a polyelectrolyte material, mixing the polyelectrolyte material with a conductive material and affixing at least two electrodes to the mixed polyelectrolyte material and conductive material.

Abstract: New artificial muscles and actuators, that are operated by hydrogen gas as working fluid stored interstitially in metal hydrides as a hydrogen sponge. These artificial muscles and actuators are operated both electrically and thermally. The artificial muscles and actuators have fast response, are compact/light-weight, are noiseless, and produce high-power density. They can be used for biomedical, space, defense, micro-machines, and industrial applications.
