Description

Micro-Electric Stimulation Clothing}

The present invention relates to electrical stimulation clothing that can provide electrical stimulation to a stimulation subject without using an artificial external power source.

In the era of the 4th Industrial Revolution, the development of wearable devices is in full swing, and various wearable devices such as smart watches, wearable glasses, and fitness bands are already being released. Wearable devices are small in size, light, and flexible. With the launch of , many functional fibers that can be used by applying wearable technology to clothing, which is a necessity that people wear all the time, are being developed.

In particular, electrical stimulation has been proven to have various effects such as improving wrinkles, promoting healing of wounds and fractures, improving muscle fatigue, improving inflammation, improving blood circulation, reducing abdominal fat, and antibacterial, so the current applied from the power supply unit stimulates muscles. Devices using Electrical Muscle Stimulation (EMS), which directly stimulate muscles without commands from the brain, are being developed.

However, these conventional devices using electrical muscle stimulation require an energy source such as a battery to apply electrical stimulation to the human body, so their construction is complicated and miniaturization is limited.

To explain in detail, in the case of functional fibers that require additional external devices such as a power supply unit for the operation of the functional fiber, an electrical stimulator that applies electrical stimulation to the electrical stimulation unit, and a portable terminal unit that controls the operation of the electrical stimulator, general fabric Compared to other products, there are bound to be limitations in maintaining the same texture and feel, so it can cause discomfort to the wearer during activities and is difficult to wear for long periods of time.

Accordingly, the present inventor, as disclosed in Republic of Korea Patent Publication No. 10-2020-0079426 “Clothing to Increase Exercise Effect,” uses the electric field generated in the human body as an energy source to create a battery that stores energy or converts energy into electrical energy. We have developed clothing that can apply constant electrical stimulation to the entire human body in contact without the need for a harvesting unit.

However, a first electrode that is in contact with the skin, a second electrode that is not in contact with the skin, and a connecting medium that electrically connects the two electrodes must be provided, so manufacturing is complicated and there is no risk of disconnection or damage between the connecting medium and the electrodes after washing. There are disadvantages such as detachment or detachment, and there is a limit to increasing the intensity of electrical stimulation to improve the effects described above due to electrical stimulation.

Accordingly, there is a need to improve the durability of electrical stimulation clothing to maintain the performance of electrical stimulation even after washing. In order to improve the effect of wearing electrical stimulation clothing, there is a need to increase the intensity of electrical stimulation applied to the skin. There is a need to develop electrical stimulation clothing that is easy to manufacture.

The electrical stimulation clothing according to the present invention includes an insulating first fiber portion having one surface in contact with the user's skin; a second fiber portion located on the opposite side of one side of the first fiber portion; A conductive adhesive layer located between the first fiber portion and the second fiber portion to bind the first fiber portion and the second fiber portion; And an electrode located on one side of the first fiber portion and electrically connected to the conductive adhesive layer.

In detail, the human body is made up of 70 to 80 percent water, a polar molecule, which causes dielectric phenomena. Whenever the human body moves, alternating current is generated due to frictional charging, and this alternating current is propagated from the area where frictional charging occurs to other parts of the human body in the form of an alternating electric field due to moisture in the human body. When the propagating alternating current electric field reaches the electrode in contact with the human body and the alternating electric field is input to the electrode, charge transfer occurs between the electrode and the conductive adhesive layer in a direction that cancels it out, and is located on the opposite side of the electrode and one side of the first fiber portion. A potential difference is formed between the conductive adhesive layers. At this time, as the alternating current electric field generated by friction charging is input to the electrode, a potential difference is formed in the form of alternating current between the electrode and the conductive adhesive layer, and the human body is stimulated by the formed electric field.

In the conventional technology, in constructing an electrode that contacts the skin and an electrode that does not contact the skin, a conductive polymer can be formed by coating or printing on an insulating fiber. In this case, due to the characteristics of the conductive polymer, the conductivity is adhesive rather than adhesive. There are problems such as electrode peeling when the wearer wears electrical stimulation clothing made of electrodes made of polymer during activities or after washing the electrical stimulation clothing. In addition, in order to increase micro-electrical stimulation, a separate connecting member is used to connect the conductive electrical stimulation unit to an electrode that does not contact the skin and an additional electrical stimulation enhancement unit.

On the other hand, the electrical stimulation clothing of the present invention can provide improved binding force by placing a conductive adhesive layer that binds the two fiber parts between the insulating first and second fiber parts. Accordingly, since the conductive adhesive layer stably attached to clothing can stably perform the role of an electrode that does not contact the skin of the prior art, microelectricity resulting from the electric field generated in the human body is transmitted through an electrode electrically connected to the conductive adhesive layer. Through this, electrical stimulation can be delivered to the clothing wearer more reliably than with conventional technologies.

Hereinafter, the electrical stimulation clothing according to the present invention will be described in detail with reference to the attached drawings.

Figure 1 is a cross-sectional perspective view and an enlarged cross-sectional view showing the electrical stimulation clothing according to the present invention.

As shown in Figure 1, the electrical stimulation clothing of the present invention includes a first fiber portion 100; Second fiber portion (200); Conductive adhesive layer 300; and electrode 400.

In detail, the first fiber portion may be a woven or non-woven fiber containing an insulating empty space.

At this time, the fiber refers to a fiber that can maintain a shape that can be worn on the human body by the user on a daily basis, can have various shapes, and serves as an insulator that can form an electric field between the conductive adhesive layer 300 and the electrode 400. Doing so is enough. Fibers have insulating properties and may include various materials that can create an electric field by causing the conductive adhesive layer 300 and the electrode 400 to have a potential difference in the same electric field, so they are not limited to specific fibers.

In a preferred example, the fiber is elastic, so the electrode 400 formed on the fiber can be in close contact with the skin of a user wearing the electrical stimulation clothing.

Stretchy fibers may include fibers in which polyurethane or spandex is synthesized with one or more fibers selected from natural fibers, nylon fibers, polyester fibers, and acrylic fibers.

As an example, the empty space included in the first fiber portion 100 may be in the form of an array formed regularly and/or irregularly in the thickness direction of the substrate, depending on the weaving method, or may be in the form of a network in which the empty spaces are entangled with each other. .

For example, the size of the empty space may be 1 to 1000 μm, specifically 20 to 500 μm, and more specifically 40 to 300 μm.

In detail, it is known that the requirements for fibers used in clothing materials are thin and long, with a thickness of approximately 10 to 30 μm. The characteristics of the organized fabric are determined by the method of crossing the fibers or weaving the loops, and the size of the empty space in the fibers that can ensure breathability, which is one of the functions of clothing, and provide an electrical connection passage, is within the above range. desirable.

The conductive adhesive layer 300 according to one embodiment of the present invention can be positioned between the first fiber portion 100 and the second fiber portion 200, which will be described later, to bind the two fiber portions.

According to one embodiment of the present invention, the conductive adhesive layer 300 may include a conductive polymer layer.

As an example, the conductive polymer may be one or more selected from the group consisting of polyacetylene, polyaniline, polypyrrole, and polythiophene, but is not limited thereto. As a practical example, conductive polymers include polyacetylene (PA), polyaniline (PANI), polypyrrolek (PPy), polythiophen (PT), and poly(3,4-ethylenedioxythiophene). ), PEDOT), polyisothianaphthene (PITN), polyphenylene vinylene (PPV), polyphenylene (PPE), polyphenylene sulfide (PPS) and polysulfur It may be one or more than one selected from nitride (polysulfur nitride, PSN), but is not limited thereto.

Figure 3 is an enlarged cross-sectional view showing the first embodiment of the electrical stimulation clothing according to the present invention.

As shown in FIG. 3, the conductive adhesive layer 300 may further include a mixture layer 320 of a conductive polymer and an adhesive polymer between the second fiber portion 200 and the conductive polymer layer 310.

At this time, the weight ratio of the conductive polymer and the adhesive polymer contained in the mixture layer 320 of the conductive polymer and the adhesive polymer may be 1:0.1 to 0.8, specifically 1:0.3 to 0.6. In order to secure adhesion between the conductive adhesive layer 300 containing adhesive polymer and the second fiber portion and at the same time have electrical properties, it is preferable to have a weight ratio in the above range.

As a specific example, the adhesive polymer may be a chemical substance such as a curing agent, or a resin that is cured by heat and/or light, and may be a resin containing a curable functional group. Examples of resins with high flexibility and elasticity include, but are not limited to, acrylate-based resins, siloxane-based resins, olefin-based elastic resins, or polyurethane-based resins.

In one embodiment of the present invention, the conductive adhesive layer 300 may contain a conductive filler and an adhesive polymer. It is possible to simultaneously secure the stability of electrical properties by conductive filler and physical bonding by curable resin.

Here, the weight ratio of conductive filler:adhesive polymer may be 1:0.2 to 0.7, specifically 1:0.3 to 0.5. In order for the conductive adhesive layer 300 to secure adhesive strength and have electrical properties at the same time, it is preferable to have a weight ratio within the above range.

As an example, the conductive filler may include one or more of metal, conductive carbon material, and conductive oxide.

Since metal itself is a very good conductor, one or more metals selected from the group of alkali metals, alkaline earth metals, transition metals, and post-transition metals, or alloys thereof, are sufficient. However, when the subject of stimulation is the human body, for more stable use, the conductive metal may be a metal that has been confirmed to be bio-safe upon contact, such as copper, gold, silver, stainless steel, aluminum, etc., but is not necessarily limited to this. .

Conductive carbon materials include, but are not limited to, carbon fiber, activated carbon, carbon nanotubes, graphite, carbon black, graphene (reduced graphene oxide), and combinations thereof.

Conductive oxides include transparent conductive oxides commonly used as transparent electrodes. Transparent conductive oxides include FTO (Fouorine doped Tin Oxide), ITO (Indium doped Tin Oxide), GZO (Ga doped ZnO), and AZO (Al doped ZnO). ), ZnO, SnO2, TiO2, etc., but are not limited thereto.

In one embodiment, when the conductive adhesive layer 300 contains a conductive filler and an adhesive polymer, the conductive filler must be able to be sufficiently impregnated into the empty space of the first fiber portion 100, so that it has a zero-dimensional form such as particles. It could be a structure.

The particle form is not particularly limited, but may be conductive carbon particles such as activated carbon, graphite, carbon black, crumpled graphene particles, and reduced graphene oxide (RGO) particles, metal particles, It may be conductive oxide particles, conductive polymer particles, or mixed particles thereof, but is not limited thereto.

Specifically, the particle size may be 1 to 1000 nm, specifically 10 to 500 nm, and more specifically 40 to 100 nm.

The electrode 400 according to the present invention may be located on one side of the first fiber portion 100, which has one side in contact with the user's skin as described above.

The electrode 400 located on one surface of the first fiber portion 100 may apply electrical stimulation to the skin by contacting the skin of the wearer of the electrical stimulation clothing.

In one embodiment of the present invention, the area of the electrode 400 may be smaller than the area of the conductive adhesive layer 300 described above. The larger the difference in area size between the conductive adhesive layer 300 and the electrode 400, the greater the strength of the electric field applied to the human body through the electrode 400.

Figure 2 is a diagram showing simulation results of electrical stimulation intensity according to size differences between the conductive adhesive layer 300 and the electrode 400.

Referring to Figure 2, Symmetric FCS is a simulation of the electric field intensity generated when the size of the electrode 400 adjacent to the human body and the size of the conductive adhesive layer 300 are the same, and Asymmetric FCS is a simulation of the electric field intensity generated when the size of the electrode 400 adjacent to the human body is the same. This is a simulation of the electric field intensity when the size of the conductive adhesive layer 300 is larger than that of the conductive adhesive layer 400. As can be seen in FIG. 2, the larger the size of the conductive adhesive layer 300 is than the size of the electrode 400, the greater the electrical stimulation effect applied to the human body by the electrode 400.

As an example, the electrode 400 is sufficient as long as it is positioned spaced apart from the conductive adhesive layer 300 and can have a potential difference, so it may include the above-described metal, conductive carbon material, conductive organic material, conductive oxide, or a combination thereof. At this time, the combination may also include composite materials such as metal and conductive carbon material, conductive polymer and conductive carbon material, and metal and conductive polymer.

In one embodiment, the electrode 400 may be configured so that at least a portion of it can be inserted into the target to which stimulation is applied. That is, the electrode 400 may include a protruding insertion area. Accordingly, the electric field is concentrated in the protruding insertion area, making it possible to apply enhanced micro-electrical stimulation to the stimulation application target.

For example, the insertion area may have a protruding shape such as a cone shape, an angled cone shape (including a pyramid shape), a needle shape, etc., but is not necessarily limited thereto.

According to one embodiment of the present invention, the conductive adhesive layer 300 and the electrode 400 may be spaced apart and electrically connected.

In one embodiment, as shown in FIG. 4, the electrical connection between the conductive adhesive layer 300 and the electrode 400 is achieved by a fluid conductive adhesive material penetrating into the pores of the first fiber portion 100 and solidifying it. You can.

In relation to the method of manufacturing electrical stimulation clothing of the present invention, which will be described later, the conductive adhesive material having fluidity may have a low viscosity at a level that can be impregnated into the empty space of the first fiber portion 100 described above.

As an example, the conductive adhesive material may be integrated with the conductive adhesive layer 300 and extend from the conductive adhesive layer 300 to penetrate the first fiber portion 100 in the thickness direction and be connected to the electrode 400.

At this time, being integrated with the conductive adhesive layer 300 and connected to the electrode 400 means that the conductive adhesive layer 300 is extended from the conductive adhesive layer 300 rather than being connected by a separate connecting member or connecting medium. ) means that the same material is connected to the electrode 400.

At the same time that the conductive adhesive layer 300 is formed from a low-viscosity conductive adhesive material, the conductive adhesive material flows in the thickness direction of the first fiber portion 100 by filling the voids included in the first fiber portion 100, forming a conductive adhesive. The layer 300 and the electrode 400 may be connected.

In detail, due to the capillary force and gravity, the conductive adhesive material may flow in the thickness direction of the first fiber portion 100 to fill the voids in the fibers, and some of the conductive adhesive material may penetrate into the fibers surrounding the voids and adjacent to them. It may be connected to the electrode 400 by penetrating the first fiber portion 100 in the thickness direction.

In one specific example, as shown in FIG. 5, the conductive adhesive layer 300 and the electrode 400 may be electrically connected by a conductive thread.

At this time, the conductive thread is capable of electrical connection and may be in the form of a metal wire such as copper, silver, or gold coated with an insulating coating, or may be in the form of a polymer fiber coated with a conductive material containing metal, and is manufactured by electrospinning. It may be in the form of a thread made of the conductive organic material itself, but the present invention is not limited thereto.

As an example, the electrical connection between the conductive adhesive layer 300 and the electrode 400 by a conductive thread may be connected to the outside of the first fiber portion 100, and may be connected through the gap of the first fiber portion. .

In order to avoid the risk of disconnection, it is preferable that the conductive thread penetrates the gap of the first fiber portion 100 to connect the conductive adhesive layer 300 and the electrode 400. At this time, the thickness of the conductive thread is as described above. It may be 1 to 1000 nm, specifically 10 to 500 nm, and more specifically 40 to 100 nm, which can be connected through the pores of the first fiber portion.

In one embodiment of the present invention, as shown in FIG. 6, the conductive adhesive layer 300 and a plurality of electrodes 400 may be connected.

As a specific example, the plurality of electrodes 400 connected to one conductive adhesive layer 300 can selectively control the area of the area where stimulation is applied to areas where fatigue occurs frequently or muscle tightness is frequent, and provide strong electricity to the corresponding area. It can be stimulating.

According to one embodiment of the present invention, the second fiber portion 200 may be conductive.

As described above, the alternating current electric field generated by the potential difference between the conductive adhesive layer 300 and the electrode 400 uses the electric field generated whenever the human body moves as an energy source, and the alternating current electric field provides micro-electrical stimulation to the human body. The conductive adhesive As the conductive second fiber portion 200 is located in the layer 300, a larger potential difference with the electrode 400 is caused, making it possible to apply enhanced microstimulation to the human body.

In addition, the conductive adhesive layer 300 can exist in a stable state by being positioned between the first fiber portion 100 and the second fiber portion 200, and the two fiber portions surround the conductive adhesive layer 300. As a result, damage from physical stimulation such as external shock can be minimized, making it possible to provide electrical stimulation clothing with improved durability.

The present invention will be described in terms of the manufacturing method of the electrical stimulation clothing.

The method of manufacturing electrical stimulation clothing according to the present invention includes the steps of applying a conductive adhesive material to the opposite side of the first fiber portion 100, which has one side in contact with the user's skin; Attaching the electrode 400 to one surface of the first fiber portion 100; Connecting the applied conductive adhesive material and the electrode 400; Bonding the second fiber portion 200 onto the applied conductive adhesive material; and curing the applied conductive adhesive material.

Specifically, the method of manufacturing electrical stimulation clothing according to the present invention involves applying a conductive adhesive material to the opposite side of the first fiber portion 100, which has one side in contact with the user's skin, and binding it to one side of the first fiber portion 100. It is completed by connecting the electrode 400 and the conductive adhesive material, binding the second fiber portion 200, and then going through a curing step. The manufacturing process is simple compared to the conventional technology, and after the conductive adhesive material is cured, the conductive adhesive layer ( Since 300) is positioned between the first fiber portion 100 and the second fiber portion 200, it has the advantage of providing electrical stimulation clothing with improved durability.

In detail, the method of manufacturing electrical stimulation clothing of the present invention may include the step of applying a conductive adhesive material to the opposite side of the first fiber portion 100, which has one side in contact with the user's skin.

As an example, the conductive adhesive material may be selected from a combination of the conductive polymer, conductive filler, and adhesive polymer described above.

In one embodiment, when a conductive polymer is used as the conductive adhesive material, the conductive adhesive material may further include a combination of a conductive polymer and an adhesive polymer. That is, after applying the conductive polymer to the opposite side of the first fiber portion 100, which has one side in contact with the user's skin, a mixture of the conductive polymer and the adhesive polymer can be applied on the additionally applied conductive polymer layer.

As the conductive adhesive material contains an adhesive polymer, the physical bonding force with each fiber portion is improved, and after the conductive adhesive material is cured, the conductive adhesive layer 300 is formed on the first fiber portion 100 and the second fiber portion ( 200), and can improve the durability of electrically stimulated clothing by attaching it stably.

According to one embodiment of the present invention, the conductive adhesive material may be a low-viscosity material with fluidity.

At this time, the low viscosity refers to a level that can be sufficiently impregnated into the empty space included in the first fiber portion 100 described above, and the viscosity of the conductive adhesive material according to one embodiment that satisfies this may be 10 to 15,000 cps. and preferably 100 to 10000 cps.

In one embodiment, the conductive adhesive material may further include a solvent to have viscosity characteristics in the above range.

As an example, the conductive adhesive material may contain 20 to 80% solvent by weight, and specifically 40 to 60% solvent by weight. In one specific example, organic solvents such as water, alcohol, acetone, N-methylpyrrolidone (NMP), ethylene glycol, propylene glycol, glycerin, etc. may be used as the solvent, but the conductive filler is used in the first fiber portion 100. It is sufficient as long as it has a viscosity that can be sufficiently impregnated into the empty space, so the present invention is not limited thereto.

At this time, when a low-viscosity conductive adhesive material is applied to the opposite side of the first fiber portion 100, which has one side in contact with the user's skin, the conductive adhesive layer 300 is formed as described above and at the same time, the low-viscosity Since the conductive adhesive material may penetrate into the pores of the first fiber portion 100 and connect to the electrode 400, the step of connecting the applied conductive adhesive material and the electrode 400 in the method of manufacturing electrical stimulation clothing of the present invention It has the advantage of being omitted, which further simplifies the manufacturing process.

In one embodiment of the present invention, the conductive adhesive material is applied to the opposite side of the first fiber portion 100, which has one side in contact with the user's skin, by one or more methods selected from printing and coating. . In manufacturing the electrical stimulation clothing according to the present invention, any method that can stably apply a certain amount of a low-viscosity conductive material is sufficient, so the present invention is not limited to the application method.

One embodiment of the present invention may include attaching the electrode 400 to one surface of the first fiber portion 100, which has one surface in contact with the user's skin.

A material selected from the above-described metal, conductive carbon material, conductive organic material, conductive oxide, or a combination thereof can be bonded to one surface of the first fiber portion 100 using a conductive adhesive, and the first fiber portion 100 can be bonded to the first fiber portion 100 using a conductive thread. Of course, the electrode 400 can be formed by weaving on one side of ). As long as the electrode 400 can be stably attached to one surface of the first fiber portion 100, the present invention is not limited thereto.

As described above in the step of connecting the applied conductive adhesive material and the electrode 400, not only can it be connected to the electrode 400 using a low-viscosity conductive adhesive material, but also the conductive adhesive material can be connected to the electrode 400 by a conductive thread. Electrodes 400 can be connected.

As an example, a conductive thread may be connected through a portion of the electrode 400 and may be attached to the electrode 400 using a conductive adhesive, and the conductive thread connected to the electrode 400 may be a first fiber portion to which a conductive adhesive material is applied. It can be connected by penetrating the gap in (100) and tying a knot. In addition, of course, the conductive thread may be exposed by being connected to the outside without passing through the gap of the first fiber portion 100.

According to one embodiment of the present invention, the step of binding the second fiber portion 200 on the applied conductive adhesive material may be included.

In one embodiment, the second fiber portion 200 bonded on the applied conductive adhesive material may be conductive.

As an example, the second fiber portion 200 may include one or more of a logo, a zipper, or a button containing a conductive material, and the conductive adhesive layer 300 and the conductive second fiber portion 200 are connected. As a result, the potential difference between the conductive adhesive layer 300 and the electrode 400 may increase, thereby increasing the intensity of electrical stimulation sensed by the clothing wearer. Furthermore, since the conductive adhesive layer 300 is bonded and positioned between the first fiber portion 100 and the second fiber portion 200, electrical stimulation clothing with improved durability can be provided.

According to one embodiment of the present invention, curing the applied conductive adhesive material may be included.

As an example, curing may be carried out by thermally removing the solvent contained in the conductive adhesive material, thereby causing physical bonding by the resin contained in the conductive composition.

Specifically, curing may be performed at a temperature range of 80 to 300°C, specifically 100 to 200°C, for 1 to 6 hours, preferably 2 to 4 hours.
