Embodiment 1

[0139] Hereinafter, embodiments of the polymer actuator in the present invention will be described. In this example, in order to confirm whether the deformation method of the electro-stimulating polymer material that deforms at a site other than the site when an electrical external stimulus is applied can be used in a polymer actuator, a predetermined voltage was applied and the measurement was performed The amount of displacement. by Figure 13 The displacement measuring device 75 shown performs this measurement.

[0140] The displacement measuring device 75 has a frame 77 for fixing an electrically irritating polymer material (gel sheet of human muscle (registered trademark), product number H0-1) 76, and the frame 77 Mobile mobile station 78. In addition, a high-voltage power supply (manufactured by Matsuda Preeision Co., Ltd., model HJPQ-30P1) 79 is provided. The high-voltage power supply 79 is connected to a fixed electrode (not shown) sandwiching the object 76 to be measur...

Embodiment 2

[0149] The distribution of the electric field vector when a voltage is applied to the polymer actuator of the present invention was analyzed by simulation. For comparison, against Figure 30 The shown structure of the shaft seal part, that is, the polymer material (shaft seal body) 1 sandwiched by the fixed electrode part with the same application area, is also simulated, and the polymer material 1 is different from the electrode holder in the application area. The electrostimulation polymer material (driving body) 11 of the present invention supported by the present invention was respectively subjected to this simulation. This simulation is performed by analyzing the distribution of electric field vectors generated in the inside of each electrostimulant polymer material when an electric field is applied to the electrode.

[0150] As a condition at this time, for the polymer material 1 sandwiched by the electrode parts 2 and 3 with the same applied electrode, the size of the elec...

Embodiment 3

[0158] Furthermore, a polymer actuator having a structure different from that of Example 2 was constructed, a voltage was applied to the polymer actuator, and the distribution of the electric field vector at this time was analyzed by simulation similarly to the case of Example 2. In this example, such as Figure 27 As shown, the electrically stimulating polymer material (driving body) 81 has a hollow ring shape whose outer peripheral surface is as large as a hemispherical surface. In addition, upper and lower electrodes 82 and 83 are arranged on the upper and lower sides of the driving body 81. In the driving body 81, the contact portion with the upper electrode 82 is a flat surface on the upper side, while the contact portion with the lower electrode 83 is a flat portion on the lower surface and a curved surface on the inner peripheral side.

[0159] If an electrical external stimulus is applied to the driver 81 from the electrodes 82 and 83, Figure 28 The electric field vector...

Abstract

It can be used in various driving sources in various driving sources. In particular, the variable volume of the polymer can be used in the valve and shaft seal device.The present invention provides a polymer motoror that has the driver with deformation through electrical stimulation, and the electrical electrodes that apply positive and negative electrical stimulus to the driver's plane on the upper and lower side -to -bottom side of the driver.The electrode has a different application area and has the following electric field distribution: through the application area, the stress distribution generated in the driver's body is biased towards the side of the positive and negative, and the driver is bent and deformed to the side of an unable to applied area.

Description

Technical field [0001] The present invention relates to a polymer actuator using a polymer material, and in particular to a valve and a shaft seal structure suitable for opening and closing of a flow path and flow control using the polymer actuator. Background technique [0002] In the past, for example, as a control of the flow path in the container, in the case of always sealing the fluid, a shaft sealing device using a sealing member is generally used. In order to seal various fluids such as air / water / oil / gas, the sealing member in this shaft sealing device uses, for example, an annular O-ring or a filling ring with a substantially circular cross-section. The main function of these sealing components is to seal the fluid, so higher sealing performance is required. [0003] Therefore, in the sealing member, generally, one side of the shaft sealing device is provided with a groove having a substantially rectangular cross-section in the axial direction formed in the same plane in ...
