▎ 摘　　要

NOVELTY - The actuator has an ion exchange polymer membrane i.e. PTFE, fixed on a side of a graphene membrane electrode. An outer power supply is connected to a signal input system. A grafted framework is provided with a fluorine-containing polymer membrane selected from a sulfonic acid group or carboxylic acid group. A graphene membrane electrode assembly is formed by graphene monomolecular multiple layers of a flexible conductive graphene film resistor. USE - Graphite-ion exchange polymer electric actuator. Uses include but are not limited to an intestinal tract, a vein micro-robot, a magnetism absorbed wheel type wall-climbing robot, an underwater robot and artificial heart valves. ADVANTAGE - The actuator has large force/displacement output during long time work. The actuator's mechanical output performance is prevented from being attenuated under air atmosphere. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a preparation method of a graphite-ion exchange polymer actuator. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a graphite-ion exchange polymer electric actuator.'(Drawing includes non-English language text)'
