In the present work we report on preparation of composite materials of polypyrrole and electroactive polymer gel using for the actuating system. Composite materials of conducting polymer and polymer gel prepared by chemical oxidative polymerization. The gels were stimulated by the application of various electric fields. The elasticity of composite materials was significantly increased with ratio of polypyrrole in the gel. The bending rate of the polymer gel under the electric fields was increased with the ratio of polypyrrole in the composite material and the magnitude of applied voltages. We also succeeded to demonstrate that many cylinders of this conducting electroactive polymer gel embedded in water solution bent uniformly toward the electrode by the application of various electric fields.
