PROBLEM TO BE SOLVED: To contrive high efficiency of a drive device itself as well as miniaturization, light-weight and energy saving thereof, and enable high speed control. SOLUTION: An electroristrictive expansion and contraction polymer Q based on an elastomer dielectric between suitable electrodes capable of adjusting its shape by the fluctuation of application voltage and current is utilized as the operation member of the drive device. The drive device is a valve device by two-way valve, three-way valve, a five-way valve or the like for regulating the flow velocity and flow rate and the like of fluid and changing over a flow passage, and an actuator or the like for generating the power of linear movement, rotational movement, linear rotational composite movement, curvature movement or the like by a drive element utilizing the electrorestrictive expansion and contraction polymer Q. Furthermore, the electrorestrictive expansion and contraction polymer Q capable of being transformed into fluctuation voltage and current by the change of the shape of fluctuating itself can be utilized as the transforming element of the drive device for transforming mechanical energy into electric energy. |
