DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to FIGS. 1A to 9, and the same reference numerals are given to the same constituent elements in FIGS. 1A to 9. It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation of the invention as claimed.

FIG. 1A is a schematic perspective view showing a composite sensor according to a first embodiment of the present invention. FIG. FIG. 1B is a view for explaining the detailed structure of the composite sensor according to the first embodiment of the present invention. In FIG. 1B, a plurality of layers of fabric made up of a sensor base are arbitrarily separated in order to facilitate understanding of the structure, The weft yarns and the warp yarns forming the multiple layers are woven together to form a single weave body.

1A and 1B, a composite sensor according to a first embodiment of the present invention includes first sensing means (described later) for sensing a plurality of physical and chemical property changes in a single sensor base 1 in a complex manner at the same time 2), a second sensing means (3), and the like.

In particular, the sensor base 1 is formed of a fabric having flexibility and stretchability so as to satisfy mobility, activity or comfort even when it is installed in an article or apparatus such as clothes or bedding.

The first sensing means 2 is disposed on the sensor base 1 and is formed of a conductive wire whose electrical resistance value changes in accordance with physical or chemical changes to output a sensing signal.

As shown in FIGS. 1A and 1B, the first sensing unit 2 includes a temperature sensing unit 2a for sensing a temperature change of the sensor base 1. The temperature sensing part 2a is disposed such that the first sensor wire 21 and the second sensor wire 22 formed of conductive wires having different electric resistance values have a contact point p.

The first and second sensor wires 21 and 22 are arranged in a fabric by a weaving method or an embroidery method and are arranged in a structure having a bent portion so that they can be contracted and expanded when a tensile force or an impact force is applied. The first and second sensor wires 21 and 22 may be arranged in the sensor base 1 by an embroidery method or a stitched method. However, in this embodiment, .

The second sensing means 3 includes a first sensing portion 31 connected to one side signal transmission line 33 disposed in the sensor base 1 and a second sensing portion 31 connected to the first sensing portion 31, And a second sensing unit 32 arranged to be viewed and connected to the other signal transmission line 34.

The sensor base 1 is made up of a woven fabric woven into a planar structure by weft and warp. Herein, the fabric is not limited to a fabric woven by a weaving method, but a concept including a knitted fabric by knitting. The sensor base 1 is mainly formed in a band shape in the accompanying drawings, but the present invention is not limited thereto, and the shape and size of the sensor base 1 may be variously changed.

On the other hand, the sensor base 1 can be woven using various types of looms such as a conventional knitting machine and a loom, but in the present embodiment, the woven fabric can be woven using a loom shown in Korean Patent Publication No. 10-2011-0083435, The weft yarn is fed to the weft yarn and the warp yarn to weave the weft yarn 1, and the conductive yarn for constituting the first and second sensing means (2, 3) as a part of the weft yarn and the warp yarn is supplied to the weaving machine, Therefore, detailed description of the detailed structure of the loom and the weaving method will be omitted.

The fabric applied to the sensor base 1 is woven so as to have a plurality of layers interlaced by weft and warp, the first and second sensing means 2, 3 being each independently arranged on different layers of the fabric have. For example, the fabric may be made of a thick fabric having a plurality of layers that are interlaced with each other by weft and warp. In this embodiment, the fabric is woven to have a plurality of layers as shown in Figs. 1A and 1B The second sensing means 3 is arranged in the upper fabric layer and the first sensing means 2 is arranged in the lower layer.

The sensor base 1 may be composed of a stretchable polymer yarn such that a part or all of the weft yarns and the warp yarns are called spun yarns or the like so that they can be stretched when an external force such as a tensile force or an impact force is applied, .

In addition, the sensor base 1 may be arranged such that discolored fiber yarns (not shown) that are discolored to specific colors upon temperature change are supplied with weft and warp. Here, the discolored fiber yarn can be obtained by impregnating the inside of the filament yarn constituting the fiber yarn with a zeolite ink, which is a discolored ink. When the discotic fiber yarn (not shown) is disposed in the sensor base 1, the temperature change can be easily detected through color change.

Hereinafter, the first sensing means 2 and the second sensing means 3 will be described in more detail.

The first sensing means 2 is constituted by a temperature sensing portion 2a arranged such that the first sensor line 21 and the second sensor line 22 have a contact point p, 21 and the second sensor line 22 are made of a conductive yarn made of a conductive material. At this time, the conductive yarns constituting the second sensor line 22 are formed of conductive yarns having different electric resistance values as compared with the conductive yarns constituting the first sensor line 21. [ Typically, the conductive yarns constituting the first and second sensor lines 21 and 22 are metal yarns having different electric resistance values. The reason why the conductive wires constituting the first and second sensor wires are formed of metal wires having different electric resistance values is that the first and second sensor wires 21 and 22 are connected to each other, So that the temperature can be measured by allowing the heat current to flow by the Seebeck effect.

The conductive yarns constituting the first and second sensor lines 21 and 22 are selected in accordance with a temperature range to be measured such as antimony, iron, gold, tungsten, copper, lead, aluminum, platinum, nickel and bismuth . For example, the conductive yarns constituting the first and second sensor lines 21 and 22 may be a combination of lead wires such as platinum and platinum rhodium, copper and constantane, copper and gold cobalt, and the like.

The first and second sensor wires 21 and 22 are arranged so as to have a plurality of bent portions as shown in FIG. 1B so that they are not stretched or damaged while being stretched and contracted even if a tensile force is applied to the sensor base 1. At this time, the bent portion is formed to have a substantially sinusoidal waveform structure.

The second sensing means 3 is configured to perform tactile sensing, humidity sensing, external load sensing, and the like at the sensor base 1, and the conductive wires are arranged in a wave structure to form signal transmission lines 33, 34 and the first and second sensing units 31 and 32 and the signal transmission lines 33 and 34 are composed of a low amplitude portion having a small amplitude. The first and second sensing units 31 and 32 are non- And a large-amplitude portion having a larger amplitude than the width portion. Here, the first and second sensing portions 31 and 32 are spaced apart from each other by a distance d while the central portion of the large width portion is removed.

The method of fabricating the signal transmission lines 33 and 34 and the first and second sensing units 31 and 32 is a method in which the conductive wire is woven in a corrugated structure and the signal transmission line, The conductive wire material is woven so as to be confined to weft and warp yarns, and the spacing interval between the first and second sensing portions 31 and 32 (the section corresponding to the center portion of the large width portion) is not constrained to the weft yarns and the warp yarns The conductive wire of the exposed section is cut and removed after woven to have an exposed section exposed to the outside.

When the second sensing means 3 is manufactured in this way, since the conductive wire is exposed and exposed above the surface of the fabric in the exposed section, it is possible to easily find the conductive wire without the necessity of finding any one among a large number of fiber yarns mixed in the fabric. There is an advantage that the wire can be cut.

When the finger is brought into contact with the space between the first sensing unit 31 and the second sensing unit 32, the second sensing unit 3 arranged as described above connects the first sensing unit and the second sensing unit by the human body So that it can be used as a contact sensor. In the case where the composite sensor according to the present invention is installed in a diaper or the like, when water is introduced into the space between the first and second sensing units 31 and 32, the signal is generated by being electrically connected by moisture, Can also be used. When the tensile force is applied to the sensor base 1, the distance d between the first and second sensing units 31 and 32 increases. As a result, the electrostatic capacitance value changes. It can also be used as a sensor that can be detected.

2A is a schematic perspective view showing a first modification of the composite sensor according to the first embodiment of the present invention. FIG. 2B is a view for explaining the detailed structure of the first variant of the composite sensor according to the first embodiment of the present invention, wherein the plurality of layers of the fabric base composed of the sensor base are shown separately in order to facilitate understanding of the structure.

Referring to FIGS. 2A and 2B, a composite sensor according to a first modification of the first embodiment of the present invention is a first sensing means 2 constituted in a sensor base 1 and detects an external load such as a tensile force or an impact force A load detection unit 2b is provided.

The first sensing unit 2 may be configured so that the temperature sensing unit 2a and the load sensing unit 2b are disposed together. However, as shown in FIGS. 2A and 2B, Will be described on the basis of the form in which only the image is arranged.

The load sensing part 2b is a wire connected between the first electrode and the control part for transmitting the electrical resistance value, which is changed when the load sensing part is deformed, to a control part (not shown) Connected to the first electrode 23 and the other signal transmission line (meaning a wire connected between the second electrode and the control unit to transmit the electric resistance value, which is changed when the load sensing unit is deformed, to the control unit) A second electrode 24 and a sense bent portion 25 formed between the first electrode 23 and the second electrode 24.

In particular, the sensing bends 25 are arranged such that a plurality of bends are brought into contact with each other by the conductive wire material w, and the bending portions are expanded when an external force is applied, contracted when an external force is released, And detects the degree of load such as pressure by the electrical resistance value.

For example, when the first and second electrodes 23 and 24 are connected to a control unit (not shown) provided for detecting an electric signal through a signal transmission line, and a small amount of current is supplied, an operation standby state is obtained. At this time, in the initial state in which no external force is applied to the sensing bent portion 25, as shown in FIG. 2B, since a plurality of bent portions are in contact with each other, The cross-sectional area is relatively large and the electrical resistance value is small. On the contrary, when the contact state of the bent portion gradually increases due to the application of the external force, the cross-sectional area of the conductive wire gradually decreases and the electrical resistance value increases. And the like.

Although the conductive wire member w constituting the load sensing portion 2b may be constituted only by the conductive w1 having conductivity as shown in the enlarged portion of Fig. 2B, as will be described later, As shown in FIG.

The conductive w1 can be selected and applied without any limitations as long as it is a linearly formed member including a conductive material capable of conducting electricity. For example, the conductive w1 may be a metal yarn formed of a conductive metal such as Cu or the like, A fiber yarn made of a plurality of filament yarns including a conductive material (conductive metal nanoparticles, metal oxide particles, graphene, etc.), a fiber yarn coated with a conductive material such as a conductive polymer, etc. can be applied , Typically a conductive metal yarn formed of stainless steel, titanium, copper (Cu) or the like can be applied. Here, the conductive yarn to which the insulating coating layer is not applied is applied.

It is preferable that the conductive w1 has a diameter in the range of 10 to 500 micrometers (占 퐉). The conductive metal sheet of the diameter range described above is used as the conductive material because the total diameter of the conductive metal sheet w and the conductive member w is not more than 1000 micrometers, So that it can be easily supplied to the embroidery of the embroidery machine.

When the diameter of the conductive w1 is 500 micrometers (탆) or more, it is difficult to weave. Conductive metal wires of 10 micrometers (㎛) or less are difficult to be massively produced by current production technology, , It is more preferable to apply a material having a diameter in the range of 20 to 100 micrometers (占 퐉), which is verified in this embodiment for conductivity, durability and quality.

FIG. 2C is a view for explaining a conductive wire rod which can be applied as a material of the load sensing part of the composite sensor according to the first embodiment of the present invention, and is a partially enlarged view.

Referring to FIG. 2C, the conductive wire rod w2 includes a sensing unit w2 disposed at the center and a conductive w1 worn around the outer surface of the sensing unit w2. .

Here, in order to ensure stable stiffness with respect to external force, the detection part (w2) is made of aramid fiber yarn having a tensile strength of 20 g / d or more, a deterioration temperature of 250 ° C or more, and a thickness of 100 to 2000 denier (Duponts product name) and Kevlar yarn (Dupont product name), and the like.

On the other hand, the conductive wire member w may be configured to be stretchable and contractible when an external force is applied. For example, the detection unit weight w2 may be composed of a sensing unit weight w2 and a protector w1, and the sensing unit w2 may be composed of an expansion and contraction line which is expanded when an external force is applied and contracted when an external force is released.

It is preferable that the stretching shrinkable filament is formed by applying a stretchable polymer yarn called a spun yarn or the like so as to be stretched when an external force is applied and reduced when an external force is released.

Herein, a silicone resin may be selected for the stretchable polymeric yarn, or polyimide, polyester, polyethylene terephthalate or a copolymer thereof may be used as the stretchable polymeric resin.

Referring to FIG. 2B, the conductive wire w has a conductive layer w3 which is formed on the outer surface of the conductive wire w1 by a conductive material. The conductive layer w3 is electrically connected to the conductive wire w1 It may be formed of a conductive material having a low electrical resistance per unit length. For example, the conductive wire rod w may be formed of stainless steel made of stainless steel as the conductive w1 and silver or copper as the conductive layer w3. In this type of conductive wire, stainless steel disposed therein has excellent rigidity and can maintain sufficient tensile rigidity, and the electric resistance value of the conductive layer (w3) formed of silver or copper is low, so that a stable sensing operation can be performed. As described above, the manufacturing cost of the conductive wire can be reduced by using materials such as stainless steel, which are relatively inexpensive instead of expensive metal materials such as silver or copper.

Hereinafter, the second to fifth embodiments according to the present invention will be described. However, detailed descriptions of the components similar to those of the first embodiment and its modifications will be omitted, Explained mainly.
