FIG. 4 is a schematic diagram showing a controller according to an embodiment of the present disclosure.

Hereinafter, embodiments of the sensor and controller according to the present disclosure will be described in detail with reference to the drawings. It should be noted that these embodiments and drawings do not limit the present disclosure. In addition, the components of the embodiment include those that can be easily replaced by those skilled in the art, or those that are substantially the same. Further, various embodiments included in the embodiment can be arbitrarily combined within a range self-evident by those skilled in the art.

《Sensor》
The sensor of the present disclosure has an elastic member and a conductive fabric portion arranged on at least a part of the surface of the elastic member, whereby when the elastic member is deformed, the conductive fabric portion is formed. It is made to expand and contract, and the conductive fabric portion is configured so that the electric resistance value increases or decreases according to the elongation rate, and the electric resistance value between a plurality of two points in the in-plane direction of the conductive fabric portion. It has a detection unit that detects parameters according to the above.

FIG. 1 is a schematic diagram showing a sensor 1 according to the first embodiment of the present disclosure. The symbols L, W, and T in FIG. 1 indicate the longitudinal direction L, the width direction W, and the thickness direction T of the sensor 1, the elastic member 10, and the conductive cloth portion 20, respectively.

As shown in FIG. 1, the sensor 1 according to the first embodiment of the present disclosure includes a rectangular parallelepiped elastic member 10 and a conductive cloth portion 20 arranged over the surface of the elastic member 10 on the upper side in the thickness direction T. Have. In the sensor 1 according to the first embodiment of the present disclosure, the distance between the two points in the in-plane direction of the conductive cloth portion 20, that is, the distance between the two points A1-A2 in the longitudinal direction L of the conductive cloth portion 20, and the conductivity. B1-B2 between two points in the direction inclined from the longitudinal direction L to the width direction W side of the cloth portion 20 are connected to the resistance measuring instrument incorporated in the detection unit 40 by the wiring 30, respectively. The electric resistance value between the two points is detected by the resistance measuring instrument.

In the sensor 1 according to the first embodiment of the present disclosure, the elastic member 10 is made of a non-woven fabric such as V-Lap (registered trademark: Teijin Limited). As a result, the elastic member 10 can be elastically deformed. Further, the conductive cloth portion 20 has a structure in which the surface of the non-conductive cloth is metal-plated. As a result, the conductive cloth portion 20 is configured so that the electric resistance value increases or decreases according to the elongation rate.

Here, when the elastic member 10 is bent, more specifically, for example, both ends of the elastic member 10 in the longitudinal direction L are below the thickness direction T, and the central portion of the elastic member 10 in the longitudinal direction L is thick. When the elastic member 10 is deformed so as to be on the upper side in the vertical direction T, the conductive cloth portion 20 arranged on the upper side in the thickness direction T of the elastic member 10 is stretched in the longitudinal direction L. In this case, the change in the elongation rate between A1 and A2 is larger than the change in the elongation rate between B1 and B2.

Further, when the elastic member 10 is twisted, more specifically, for example, the left end portion in the longitudinal direction L and the front side portion in the width direction W of the elastic member 10 are on the lower side in the thickness direction T, and the length of the elastic member 10 is long. The left end portion in the direction L and the back side portion in the width direction W are on the upper side in the thickness direction T, and the right end portion in the longitudinal direction L and the front side portion in the width direction W of the elastic member 10 are in the thickness direction T. When the elastic member 10 is deformed so that the right end portion of the elastic member 10 in the longitudinal direction L and the inner portion in the width direction W are on the lower side in the thickness direction T on the upper side, the thickness direction of the elastic member 10 The conductive cloth portion 20 arranged on the upper side of T is stretched in a direction inclined from the longitudinal direction L to the width direction W side. In this case, the change in the elongation rate between A1 and A2 is smaller than the change in the elongation rate between B1 and B2.

Therefore, for example, the elongation rate of the conductive cloth portion 20 between A1-A2 and B1-B2 differs between the case where the elastic member 10 is bent and the case where the elastic member 10 is twisted. Further, the elongation rate of the conductive cloth portion 20 between A1-A2 and B1-B2 also increases or decreases depending on the degree of bending and twisting of the elastic member 10 and the twisting angle.

That is, in the sensor 1 according to the first embodiment of the present disclosure, the conductive cloth portion 20 between A1-A2 and B1-B2 depends on the mode of deformation of the elastic member 10, particularly bending and twisting, and the degree thereof. Since the behavior of the combination of the electric resistance values is different, it is possible to detect the deformation mode of the elastic member 10, particularly the bending and twisting, and the degree thereof.

Note that FIG. 1 is not intended to limit the sensors of the present disclosure.

<Elastic member>
The elastic member may be any member that can be elastically deformed when an external force such as stretching, compression, bending, or twisting is applied. Examples of the elastic member include cushioning materials such as rubber, non-woven fabric, urethane, or gel body, and these materials can be used alone or in combination of two or more, but are limited thereto. Not done. Further, even if the same material is used, the same type of material having different tensile elastic modulus, compressive elastic modulus, flexural modulus or torsional modulus may be used in combination. More specifically, the elastic member may be a V-Lap (registered trademark: Teijin Limited) non-woven fabric alone, or a combination of the non-woven fabric and a molded product other than the non-woven fabric.

The shape of the elastic member is not particularly limited, but may be, for example, a spherical shape, a hemispherical shape, a rectangular parallelepiped shape, a pillar shape, or the like.

The elastic member can have a plurality of different surfaces from each other. Examples of the shape of such an elastic member include a rectangular parallelepiped shape and a pillar shape. It is not essential that the boundary between the faces is a corner, and the corner may have a rounded shape, for example. Further, the surface of the elastic member may be a flat surface or a curved surface. Therefore, the surface of the elastic member may be rounded, for example, or may have some unevenness or the like. Further, the elastic member can have a pair of surfaces facing each other.

The conductive fabric portion is a fabric portion having conductivity, flexibility, and breathability. Examples of the conductive cloth portion include a cloth formed of conductive fibers and optionally non-conductive fibers, or a cloth obtained by subjecting a non-conductive cloth to a conductive treatment, for example, metal plating. Examples of the conductive fiber include iron, copper, aluminum, stainless steel, gold, and silver, and a conductive metal thread made of an alloy or compound of these metals, a conductive carbon fiber, and the like. .. Examples of non-conductive fibers include resin fibers such as nylon, polyester, polyethylene, polystyrene, and polyethylene terephthalate. Examples of the metal plating include the above-mentioned metal plating. As a method of metal plating, for example, after pattern printing polypyrrole on a substrate, selective metal plating on polypyrrole can be mentioned.

Further, as the conductive cloth, a cloth having a conductive portion formed on the cloth and pasted on another cloth can also be mentioned. In this case, if a general hot melt adhesive is used to attach the fabrics to each other, the air permeability may be reduced. Therefore, by using a woven fabric in which the hot melt adhesive is arranged in dots on the mesh-shaped woven fabric, the fabric on which the conductive portion is formed and another fabric are attached to each other, the air permeability should not be deteriorated. Is preferable.

Further, the conductive cloth portion is configured so that the electric resistance value increases or decreases according to the elongation rate. More specifically, the conductive fabric portion can be configured such that the elongation rate increases, that is, the electrical resistance value increases or decreases according to the elongation of the conductive fabric portion.

The electric resistance value increases with the in-plane elongation of the conductive cloth, for example, a cloth formed of conductive fibers and optionally non-conductive fibers, or a non-conductive cloth. Can be mentioned, but is not limited to, a cloth which has been made conductive, for example, metal-plated. Although not limited by the principle, these conductive fabrics have an electric resistance value according to an increase in the elongation rate due to a decrease in the contact area between the conductive portions due to a gap between the fibers due to the elongation. Is expected to increase.

Further, the electric resistance value decreases according to the in-plane elongation of the conductive cloth. In the non-stretched state, the contact area between the conductive fibers is small, and when the conductive fabric is stretched, each of them is Examples include, but are not limited to, fabrics formed of conductive fibers and optionally non-conductive fibers such that the contact area between the conductive fibers is increased. Such a cloth is not particularly limited, but more specifically, a cloth configured so that the metal is held between the fibers constituting the conductive cloth by metal plating can be mentioned.

The conductive fabric portion is arranged on at least a part of the surface of the elastic member so that the conductive fabric portion expands and contracts when the elastic member is deformed. More specifically, the conductive fabric portion is arranged on at least a part of the surface of the elastic member, so that when the elastic member is compressed, stretched, bent, twisted, or the like, the elastic member It can expand and contract according to the deformation of the part of the surface where the conductive cloth portion is arranged.

The surface of the conductive fabric portion can be covered with a protective member. As a result, deterioration of the conductive cloth portion due to rubbing or the like can be suppressed, and the durability of the sensor can be improved.

Examples of the protective member include, but are not limited to, a non-conductive cloth layer or a resin layer.

Further, another elastic member may be arranged on the surface of the conductive cloth portion as a protective member.

The conductive fabric portion is arranged on at least a part of the surface of the elastic member. The conductive fabric portion may be one or more. When the elastic member has a plurality of different surfaces from each other, the plurality of conductive fabric portions may be arranged on all or a part of the plurality of different surfaces of the elastic member.

When a plurality of conductive fabric portions are arranged on all or a part of a plurality of different surfaces of an elastic member, between a plurality of two points in the in-plane direction of the conductive fabric portions arranged on each surface. By detecting the parameter corresponding to the electric resistance value of, the three-dimensional deformation of the elastic member can be detected as the parameter corresponding to the electric resistance value of the conductive cloth portion.

In particular, when the elastic members have a pair of surfaces facing each other and the conductive fabric portions are arranged on the pair of surfaces, the in-plane direction of the conductive fabric portion on each surface. By detecting the parameter corresponding to the electric resistance value between the plurality of two points, it is possible to separately detect bending, twisting, stretching, and compression of the elastic member.

The conductive cloth portion is composed of a first conductive cloth portion and a second conductive cloth portion arranged so as to have a distance from each other, and the first conductive cloth portion and the second conductive cloth portion. For each portion, a configuration may be configured in which a parameter corresponding to the electric resistance value between the two points is detected. When such a configuration is adopted, it is possible to reduce the portion of the elastic member covered with the conductive cloth portion, and it is possible to reduce the cost and increase the degree of freedom in design.

<Parameters according to the electrical resistance value>
In the sensor of the present disclosure, a parameter corresponding to the electric resistance value between a plurality of two points in the in-plane direction of the conductive cloth portion is detected by the detection unit.

It may be there. The distance between the two points in the in-plane direction of the conductive cloth portion can be two points that are not parallel to each other. Here, the term "non-parallel" means that the straight line connecting two points is not parallel to the straight line connecting the other two points when the conductive cloth portion is viewed from a direction perpendicular to the surface. It means that. Here, the angle between the straight line connecting two points and the straight line connecting the other two points may be 0 ° to 90 °.

Further, the two points of the conductive cloth portion may be on non-identical planes.

When the two points in the in-plane direction of the conductive cloth portion are two points non-parallel to each other, and / or when the two points of the conductive cloth part are on a non-uniform plane. It is easy to make the parameters according to the electric conductivity between each two points different with the deformation of the elastic member. Therefore, more various deformations of elastic members, such as bending and twisting, can be detected while being more accurately distinguished.

When the conductive fabric portion is composed of a first conductive fabric portion and a second conductive fabric portion arranged so as to have a distance from each other, at least one of a plurality of two points is provided. One may be between two points of the first conductive cloth portion, and at least one of the plurality of two points may be between two points of the second conductive cloth portion.

A conductive portion composed of a first conductive fabric portion 21'and a second conductive fabric portion 22'arranged so as to have a distance from each other is arranged.

In the configuration as shown in FIG. 3, when the elastic member 10 is bent, more specifically, when both ends of the elastic member 10 in the longitudinal direction L are bent downward in the thickness direction T, the thickness of the elastic member 10 is increased. The conductive fabric portions 21 and 22 arranged on the upper side of the direction T are stretched in the longitudinal direction L.
