Abstract

PROBLEM TO BE SOLVED: To provide a driving device which can be used for an actuator or a switch to be operated making use of the volumetric change, and has the memory property by providing the organic polymer/monomer composite material whose volume is reversibly changed depending on the temperature history and a heating body, and regulating the attainable temperature of the heating body. SOLUTION: A heating body 1 is provided in contact with a composite material 2 in which the monomer organic material particles 2a are dispersed in the organic polymer 2b. The original composite material 2 is in the second color condition (whiteturbid), and its volume is V2 . When the heating body 1 is heated to the temperature >= the first prescribed temperature T1 higher than the normal temperature and <= the second prescribed temperature T2 , and its temperature is returned to the normal temperature, the composite material 2 becomes in the first color condition (transparent), and its volume becomes V1 (V1 <V2 ). When the composite material 2 is re-heated to the prescribed temperature T2 , and then the temperature is returned to the normal temperature, it becomes in the second color condition, and its volume is returned to V2 . The surface of the composite material 2 is shifted in an arbitrary direction through the volumetric change.

2. Description of the Related Art As microfabrication technology advances, small actuators and switches are required. Along with this, the drive source for moving the actuators and switches is also required to be small and simple in structure.

Since the piezo element has no memory property and returns to the state before the power is turned on when the power is turned off, it is necessary to always turn on the power to maintain the state after switching the switch. For example, it is not suitable for a usage method in which a switch operation is restarted halfway after a long absence of power.

Hereinafter, the present invention will be described in more detail. The inventor has long been engaged in the development of a reversible thermosensitive recording material of the organic polymer / low molecular weight composite material type, which is one type of thermosensitive recording material typified by thermal paper. This is mainly composed of a resin film in which an organic low-molecular substance such as a higher alcohol or a higher fatty acid is dispersed, and is used by being provided on a support such as a film. No., JP-A-55-15419
No. 8 is known. As shown in FIG. 6, this type of reversible thermosensitive recording material has a first temperature higher than room temperature.
Specific temperature above T 1 and the first color state (transparent state) by heating to a second specific temperature T 2 less, T 2
By heating as described above, the second color state (white turbid state)
As with the conventional irreversible thermosensitive recording material, it is possible to form an image with a thermal head or a hot stamp and to erase an image by the same means.

When the volume of this material is compared between the transparent state and the cloudy state, the transparent state has a smaller volume than the cloudy state. Then, in the reversible change between the transparent state and the cloudy state, the volume also changes reversibly. In addition, at room temperature, the changed volume is stably maintained. This volume change itself has been known for some time, but no proposal has been made to apply it to any driving source. The reason for this is that only engineers specializing in display materials were involved in this material, and only film-like reversible thermosensitive recording materials having a thickness of several μm to about several tens of μm were obtained due to manufacturing technology. And the like. However, the present inventors have already found that the reversible thermosensitive recording materials can be processed to an arbitrary thickness of several hundred μm to 1 mm or more by overlapping and thermocompression bonding. Then, as a result of constantly thinking that this could be applied to something, they came to the present invention.

Here, since V 1 <V 2 , the stroke is a contraction stroke and the stroke is an expansion stroke. The movement of the external object by the expansion and contraction is the gist of the driving device of the present invention. Since the volume change of the organic polymer / low molecular weight composite material is isotropic, all surfaces of the organic polymer / low molecular weight composite material (2) move reversibly as shown by a thick arrow in FIG. On the other hand, in FIG. 1B, by providing a wall (3) around the organic polymer / low molecular weight composite material (2), the direction in which the surface of the organic polymer / low molecular weight composite material (2) moves can be changed. Can be limited. FIG.
In (b) to (d), the movement is all limited to one direction, but there may be a usage in which the movement is performed in two or more directions. FIG.
