Problems solved by technology

[0005] In such an actuator, when the thickness of the ion exchange membrane is increased in order to increase the displacement amount, since the operation is dominated by the diffusion speed of ions, there is a problem that high-speed responsiveness cannot be obtained.

[0040] First, the first embodiment of the actuator of the present invention will be described.

[0041] figure 1 is a cross-sectional view showing a first embodiment of the actuator of the present invention, figure 2 It is a schematic diagram which shows the drive state of the actuator of 1st Embodiment.

[0042] The actuator 1 is composed of a laminate in which a plurality of electrodes 11 , a plurality of cation exchange resin membranes 12 , and a plurality of anion exchange resin membranes 13 are stacked. In this embodiment, as figure 1 As shown, it consists of four cation exchange resin membranes 12 , three anion exchange resin membranes 13 , and eight electrodes 11 .

[0043] like figure 1 As shown, the actuator 1 is alternately laminated with cation exchange resin membranes 12 and anion exchange resin membranes 13 .

[0044] Furthermore, one electrode 11 is arranged between the cation exchange resin membrane 12 and the anion exchange resin membrane 13 .

Abstract

Provided are an actuator that is small, superior in terms of high-speed response, and capable of large displacement, and a manufacturing method that can easily manufacture the actuator. The actuator is configured by a laminated body including multiple electrodes(1), multiple cation-exchange resin films(12), and multiple anion-exchange resin films(13). The cation-exchange resin films (12) and the anion-exchange resin films (13) are stacked alternately, and each of the cation-exchange resin films (12) and the anion-exchange resin films (13)is sandwiched between two of the electrodes (11). A voltage is applied such that the electrodes between adjacent ones of the cation-exchange resin films (12) and anion-exchange resin films (13) have the same polarity.

Description

technical field [0001] The present invention relates to an actuator and a manufacturing method thereof. Background technique [0002] In recent years, in the medical field, the micromechanical field, and the like, the need for small-sized actuators is increasing. [0003] Such a small actuator is required to be driven at a low voltage, as well as being small. Various attempts have been made to achieve such a reduction in voltage (for example, see Patent Document 1). [0004] Conventionally known small-sized actuators have mainly used ion exchange membranes in which materials are shrunk / swollen by the movement of ions. [0005] In such an actuator, when the thickness of the ion exchange membrane is increased in order to increase the displacement amount, since the operation is dominated by the diffusion speed of ions, there is a problem that high-speed responsiveness cannot be obtained.
