Description

Technical Field

[0001] This invention relates to the field of smart wearable device technology, and in particular to a smart garment based on electrical stimulation and its elastic electrode pack structure. Background Technology

[0002] With the development of smart wearable technology, smart clothing integrating conductive electrodes, such as EMS (Electrical Muscle Stimulation) functional clothing and physiological signal monitoring clothing, is being used more and more widely. Among them, EMS functional clothing outputs low-frequency electrical signals to the human body through conductive electrodes in contact with the skin, simulating the original movement commands issued by the brain, directly stimulating muscle contraction, and achieving effects such as passive exercise and fitness shaping. Market demand for this type of clothing is growing daily.

[0003] One of the core components of this type of smart clothing is the conductive electrode (i.e., conductive sheet) that comes into direct contact with the human skin. To achieve optimal functional effects (such as good electrical pulse stimulation or physiological signal acquisition), the conductive electrode typically needs to maintain a good and stable contact with the skin. However, currently available, cost-effective, and scalable conductive sheets (such as conductive PU sheets) generally suffer from insufficient elasticity or even a complete lack of elasticity. Once this inelastic conductive sheet is directly fixed to the clothing fabric, the fixed area loses its elasticity. For example, in some existing EMS clothing products, the electrode packs located on the thigh area have an inelastic portion that accounts for more than 70% of the entire thigh circumference, severely limiting the stretchability of the clothing in this area. This results in a significant reduction in the elasticity of the clothing in this area, severely impacting the comfort and ease of movement when wearing it.

[0004] Therefore, how to ensure good contact between the conductive sheet and human skin while maintaining adjustable elasticity in the overall electrode pack structure, including the non-elastic conductive sheet, thus balancing the fit between the electrode and the skin and the overall comfort of the garment, is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent garment based on electrical stimulation and its elastic electrode pack structure, so as to solve the technical problems in the prior art that the elasticity of the electrode pack area is greatly reduced and the wearing comfort is poor due to the insufficient elasticity of the conductive sheet itself and the need to fix it to the garment fabric over a large area.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: This invention proposes an elastic electrode pack structure for smart clothing based on electrical stimulation, comprising: First elastic fabric layer; The second elastic fabric layer is fixed to one side of the first elastic fabric layer, and the surface of either the first elastic fabric layer or the second elastic fabric layer facing the human skin has a bonding area. A conductive sheet is fixed to the bonding area for contact with human skin; Conductive wires are electrically connected to the conductive sheet. A fixing part is used to fix at least a portion of the edge of the second elastic fabric layer to the first elastic fabric layer; Wherein, at least a portion of the edge of the joining area is spaced apart from the fixing portion, thereby forming an elastic region on the elastic fabric layer between the at least a portion of the edge of the joining area and the fixing portion. The elastic region retains elasticity and is used to compensate for the lack of elasticity of the conductive sheet when the elastic electrode package structure is subjected to external force stretching.

[0007] In one embodiment, the tensile properties of the elastic electrode pack structure in different directions are adjusted by adjusting the area of ​​the elastic region or by adjusting the position of the bonding region on the elastic fabric layer.

[0008] In one embodiment, an elastic buffer layer is provided between the first elastic fabric layer and the second elastic fabric layer, and the elastic buffer layer fills the accommodating space formed between the first elastic fabric layer and the second elastic fabric layer.

[0009] In one embodiment, the elastic electrode pack structure further includes a limiting material layer, which is fixedly connected to the second elastic fabric layer by a second fixing part. The second fixing part is distributed around the periphery of the elastic buffer layer and limits and fixes the elastic buffer layer between the limiting material layer and the second elastic fabric layer.

[0010] In one embodiment, the elastic electrode pack structure further includes a limiting material layer, at least a portion of the edge of the limiting material layer being fixedly connected to the first elastic fabric layer and the second elastic fabric layer via the fixing portion.

[0011] In one embodiment, the conductive sheet includes a conductive lug, the surface of which is fixed with a reinforcing layer. The conductive lug and the reinforcing layer are fixedly connected to the second elastic fabric layer and the first elastic fabric layer through the fixing part. The conductive lug is provided with a connector device, and the conductive sheet is electrically connected to the conductive wire through the connector device.

[0012] In one embodiment, the conductive sheet includes a conductive lug that is bent and extends into the space between the second elastic fabric layer and the first elastic fabric layer.

[0013] In one embodiment, the conductive sheet includes a conductive lug. The conductive sheet extends from the surface of the second elastic fabric layer to the fabric edge of the second elastic fabric layer, and continues to bend inward from the fabric edge of the second elastic fabric layer and extend along the back side of the second elastic fabric layer until the conductive lug extends into the space between the second elastic fabric layer and the first elastic fabric layer.

[0014] In one embodiment, the conductive sheet is connected to a connector device, and the conductive sheet is electrically connected to the conductive wire through the connector device; the elastic electrode package structure further includes an insulating sheet, which is fixed to the conductive sheet and covers the surface of the connector device, and the projected area of ​​the insulating sheet is more than 5% larger than the projected area of ​​the exposed conductive part of the connector device.

[0015] In one embodiment, the area of ​​the conductive sheet is smaller than the area of ​​the second elastic fabric layer.

[0016] In one embodiment, the fixing part is formed by one or more of the following methods: sewing, hot pressing of adhesive film, or adhesive bonding.

[0017] The present invention also proposes an intelligent garment based on electrical stimulation, comprising a garment body and an elastic electrode pack structure as described above disposed on the garment body.

[0018] In one embodiment, the smart wearable textile product further includes a functional module disposed on the garment body, wherein the conductive sheet is electrically connected to the functional module as an electrical stimulation output electrode; the functional module has at least an electrical stimulation function, which includes, but is not limited to, one or more of EMS electrical stimulation, NMES electrical stimulation, TENS electrical stimulation, and IFT electrical stimulation; the functional module may also optionally be configured with non-electrical stimulation additional functions, which include, but are not limited to, heating function, electrocardiogram acquisition function, and EMG electromyography acquisition function.

[0019] The technical solution provided by this invention has the following technical effects: 1. This invention provides an intelligent garment based on electrical stimulation and its elastic electrode pack structure. The elastic electrode pack structure includes a first elastic fabric layer, a second elastic fabric layer fixed to the first elastic fabric layer, a conductive sheet with essentially no elasticity fixed to the joint area of ​​the second elastic fabric layer, and a fixing part that fixes the first elastic fabric layer and the second elastic fabric layer. At least a portion of the edge of the joint area is spaced apart from the fixing part, so that an elastic region is formed on the elastic fabric layer between at least a portion of the edge of the joint area and the fixing part, which still retains elastic stretching properties. This invention, through the structural design of reserving an elastic region at the edge of the joint area, allows the electrode pack made of the non-elastic conductive sheet to still exhibit adjustable elasticity. While ensuring good contact between the conductive sheet and human skin, it overcomes the shortcomings of existing non-elastic electrode packs that seriously affect the elasticity and wearing comfort of clothing, thus balancing the conductive sheet's conductivity and wearing comfort.

[0020] 2. By adjusting the area of ​​the elastic region, the elasticity of the electrode pack can be flexibly controlled according to the different elasticity requirements of different products, making it highly adaptable and versatile.

[0021] 3. By setting a reinforcing layer, the adverse effects of fixing processes such as sewing on the strength of conductive sheets can be effectively avoided, thereby improving the structural reliability and service life of the product.

[0022] 4. By hiding the connection structure between the conductive wire and the conductive sheet behind the elastic buffer layer or between the elastic buffer layer and the second elastic fabric layer, and optionally bending and covering the conductive sheet, the aesthetic appearance of the product is effectively improved.

[0023] 5. By setting a limiting material layer to limit and fix the elastic cushioning layer, the elastic cushioning layer is prevented from shifting during wear and use, which further improves the reliability and comfort of the product. Moreover, by selecting the material of the limiting material layer, better relative sliding between the limiting material layer and the first elastic fabric layer can be achieved, which is beneficial to the use effect such as stretching and deformation.

[0024] 6. By setting insulating sheets and quantitatively limiting their area ratio relative to the exposed conductive parts, the product's insulation, protection, and waterproof performance are balanced, further improving the product's safety and service life. Attached Figure Description

Detailed Implementation

[0026] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention, primarily used to illustrate the embodiments and to explain the operating principles of the embodiments in conjunction with the relevant descriptions in the specification. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0027] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0028] Reference Figures 1-3 This embodiment provides an elastic electrode pack structure 100 for smart clothing based on electrical stimulation, including a first elastic fabric layer 1, a second elastic fabric layer 3, a conductive sheet 4, and a fixing part 5.

[0029] The aforementioned smart clothing based on electrical stimulation can be one of the following: EMS (Electrical Muscle Stimulation), NMES (Neuromuscular Electrical Stimulation), TENS (Transcutaneous Electrical Nerve Stimulation), or IFT (Interferential Therapy); or smart clothing that simultaneously possesses electrical stimulation and heating functions; or smart clothing that simultaneously possesses both EMS (Electrical Muscle Stimulation) and EMG (Electromyography) functions. Furthermore, in this embodiment, the smart clothing may also include a functional module electrically connected to the aforementioned conductive sheet 4 (i.e., the electrical stimulation output electrode). This functional module possesses at least one or more of the following electrical stimulation functions: EMS, NMES, TENS, and IFT. It may also optionally be configured with non-electrical stimulation additional functions such as heating, ECG acquisition, and EMG acquisition to meet the physiotherapy and monitoring needs of different application scenarios.

[0030] The first elastic fabric layer 1 can be a base fabric layer used to form a garment. The second elastic fabric layer 3 is fixed to one side of the first elastic fabric layer 1. In this embodiment, the second elastic fabric layer 3 is fixed to the side of the first elastic fabric layer 1 closest to the human skin.

[0031] The conductive sheet 4 is fixed to the surface of the second elastic fabric layer 3 on the side away from the first elastic fabric layer 1, and its surface comes into contact with human skin during use; the conductive sheet 4 is a sheet with conductive properties, such as conductive PU sheet, textile sheet coated with conductive material, etc.; such conductive sheets usually have insufficient elasticity or even have almost no elasticity.

[0032] The second elastic fabric layer 3 has a bonding area 32 on the side facing the human skin. The conductive sheet 4 is fixed to the bonding area 32 of the second elastic fabric layer 3. The fixing method between the conductive sheet 4 and the second elastic fabric layer 3 can be one or a combination of sewing, hot pressing of adhesive film, or adhesive bonding. Alternatively, one or more other materials can be added between the two layers of conductive sheet 4 and the second elastic fabric layer 3 to enhance the fixing.

[0033] The fixing part 5 securely connects at least a portion of the edge of the second elastic fabric layer 3 to the first elastic fabric layer 1 as a single unit. The fixing part 5 can be formed by one or more methods, such as sewing (one or more stitches, any sewing method), hot pressing of adhesive film, or adhesive bonding. The number of fixing parts 5 can be one or more, for example, they can be arranged in a closed ring at intervals along the edge of the second elastic fabric layer 3 (e.g., Figure 2 (As shown), it can also be set only on the opposite sides or some local positions of the second elastic fabric layer 3.

[0034] The second elastic fabric layer 3 loses its elasticity in the bonding area 32 due to the fixation of the conductive sheet 4. (Continue referring to...) Figures 1-3 The bonding region 32 has an edge 321, and the fixing part 5 is spaced apart from at least a portion of the edge 321 of the bonding region 32, that is, the area of ​​the bonding region 32 is smaller than the area of ​​the second elastic fabric layer 3. Therefore, an elastic region 9 is formed on the second elastic fabric layer 3 between at least a portion of the edge 321 of the conductive sheet 4 and the fixing part 5, wherein... Figure 3 The elastic region 9 is shown in shaded area. The second elastic fabric layer 3 at the elastic region 9 retains its own elasticity. When the elastic electrode package structure 100 as a whole is stretched by an external force, the elastic region 9 can produce elastic deformation, thereby compensating for the lack of elasticity of the conductive sheet 4 itself on a macroscopic level, and significantly improving the elasticity of this region. Since the first elastic fabric layer 1 itself is elastic, the overall elasticity of the elastic electrode package structure 100 is guaranteed.

[0035] In addition, the area of ​​the elastic region 9 can be adjusted by adjusting the distance between the fixing part 5 and the edge 321 of the joining area 32. The larger the area of ​​the elastic region 9, the stronger the stretchability. Alternatively, the position of the joining area 32 on the second elastic fabric layer 3 can be adjusted so that the stretchability of the elastic electrode package structure 100 in different directions can be adjusted according to product requirements.

[0036] In this embodiment, the area of ​​the conductive sheet 4 is smaller than the area of ​​the second elastic fabric layer 3, thereby achieving a better fixing effect on the conductive sheet 4. In other embodiments, the area of ​​the conductive sheet 4 can be larger than the area of ​​the second elastic fabric layer 3, as long as the area of ​​the bonding area 32 is smaller than the area of ​​the second elastic fabric layer 3.

[0037] Although this embodiment uses the example of the second elastic fabric layer 3 being fixed to the side of the first elastic fabric layer 1 closest to the human skin, and the conductive sheet 4 being fixed to the side of the second elastic fabric layer 3 closest to the human skin, it is not limited to this. In other embodiments, the second elastic fabric layer 3 is fixed to the side of the first elastic fabric layer 1 furthest from the human skin, and the conductive sheet 4 is fixed to the side of the first elastic fabric layer 1 closest to the human skin; this is also a feasible technical solution. That is, the positions of the first elastic fabric layer 1 and the second elastic fabric layer 3 can be interchanged, while the conductive sheet 4 is always located on the side closest to the human skin.

[0038] like Figure 1 as well as Figure 2 As shown, the elastic electrode pack structure 100 of this embodiment also includes a conductive wire 7 and a connector device 8 connecting the conductive wire 7 and the conductive sheet 4. The connector device 8 can be a snap fastener, a four-button fastener, or other connection structure capable of achieving electrical conductivity. The first elastic fabric layer 1 may have wire holes for the conductive wire 7 to pass through, thereby allowing the conductive wire 7 to be arranged on either side of the first elastic fabric layer 1, such as... Figure 2 The conductive lines 7 and 7' are shown in the middle.

[0039] The conductive sheet 4 may include a conductive lug 41, which is fixedly connected to the second elastic fabric layer 3 and the first elastic fabric layer 1 via a fixing part 5. A connector device 8 is disposed on the conductive lug 41. In this embodiment, the connector device 8 is disposed at the free end of the conductive lug 41, which is spaced apart from the fixing part 5.

[0040] A reinforcing layer 6 is fixed to the surface of the conductive sheet 4 away from the second elastic fabric layer 3 and the first elastic fabric layer 1. The reinforcing layer 6 and the conductive sheet 4 can be fixed by means of adhesive bonding or hot pressing of adhesive film. The reinforcing layer 6 is fixed to the surface of the conductive ear 41 of the conductive sheet 4. The reinforcing layer 6 and the conductive ear 41 are fixedly connected to the second elastic fabric layer 3 and the first elastic fabric layer 1 through the fixing part 5, so as to avoid the fixing part 5 affecting the structural strength of the conductive ear 41 itself during the sewing process. In some other embodiments, the reinforcing layer 6 may not be provided, which can be determined according to the actual requirements of the product standard.

[0041] An elastic buffer layer 2 can also be provided between the first elastic fabric layer 1 and the second elastic fabric layer 3. For example... Figure 2 As shown, the elastic buffer layer 2 fills the space formed between the first elastic fabric layer 1 and the second elastic fabric layer 3. The elastic buffer layer 2 can be a sponge or other elastic filling material. Its function is that the human body surface is usually curved, and the addition of the elastic buffer layer 2 can make the conductive sheet 4 fit the skin better. For areas where the human body surface is relatively flat, the elastic buffer layer 2 may not be required.

[0042] It should be noted that the elastic buffer layer 2 and the second elastic fabric layer 3 can be fixed by adhesive or hot pressing of adhesive film, or they can be left unfixed; the elastic buffer layer 2 and the first elastic fabric layer 1 are not fixedly connected. When the elastic buffer layer 2 is not provided, the second elastic fabric layer 3 and the first elastic fabric layer 1 in this area are also not fixedly connected, so as to ensure that the layers in the elastic area 9 can slide relative to each other and deform freely, thereby ensuring the elastic deformation capability of the elastic area 9.

[0043] Example 2 like Figure 4 as well as Figure 5 As shown, this embodiment provides an elastic electrode pack structure 200. The difference between this embodiment and Embodiment 1 is that the other end 42 of the conductive sheet 4, opposite to the conductive lug 41, is fixedly connected to the second elastic fabric layer 3 and the first elastic fabric layer 1 via a fixing part 5. In some other embodiments, more portions fixedly connected to the second elastic fabric layer 3 and the first elastic fabric layer 1 can be added to the conductive sheet 4; the number and size of these fixedly connected portions are not limited. Because the fixedly connected portions of the conductive sheet 4 are fixedly connected to the second elastic fabric layer 3 and the first elastic fabric layer 1 via the fixing part 5, the elastic electrode pack loses its elasticity at these fixedly connected points; while the locations of the conductive sheet 4 not fixedly connected to the second elastic fabric layer 3 and the first elastic fabric layer 1 retain elasticity due to the elastic regions 9a and 9b. Therefore, through the above arrangement, the tensile elasticity of the elastic electrode pack in different directions can be freely defined or adjusted. The remaining structure of this embodiment is the same as that of Embodiment 1, and will not be described again here.

[0044] Example 3 like Figure 6As shown, this embodiment provides an elastic electrode package structure 300. Based on Embodiment 1, this embodiment further adds a limiting material layer 11. The limiting material layer 11 and the second elastic fabric layer 3 are fixedly connected by a second fixing part 10. The fixing method can be one or more combinations of sewing (one or more stitches, various sewing methods are acceptable), hot-pressing adhesive film bonding, or adhesive bonding. The second fixing part 10 is distributed around the periphery of the elastic buffer layer 2 and limits and fixes the elastic buffer layer 2 between the limiting material layer 11 and the second elastic fabric layer 3, thereby limiting and fixing the elastic buffer layer 2 within the space between the second elastic fabric layer 3 and the first elastic fabric layer 1, preventing the elastic buffer layer 2 from shifting during wear and use. The limiting material layer 11 can be fabric or other suitable materials. With this structure, the fixing effect of the elastic buffer layer 2 is more reliable. Furthermore, the coefficient of friction between the limiting material layer 11 and the first elastic fabric layer 1 can be adjusted according to the material of the limiting material layer 11, thereby achieving better relative sliding between the limiting material layer 11 and the first elastic fabric layer 1, which is beneficial for tensile deformation and other performance effects. The remaining structures of this embodiment are the same as in Embodiment 1, and will not be described again here.

[0045] Example 4 like Figure 7 As shown, this embodiment provides an elastic electrode pack structure 400. This embodiment is a variant of embodiment 3. In this embodiment, at least a portion of the edge of the limiting material layer 11 is fixedly connected to the second elastic fabric layer 3 and the first elastic fabric layer 1 by the fixing part 5. Thus, in this embodiment, the second fixing part 10 can be retained or removed; that is, either the fixing part 5 or the second fixing part 10 can be used to fix the limiting material layer 11, or both can be combined to fix the limiting material layer 11, which is beneficial to the flexibility of the processing technology.

[0046] The limiting material layer 11 can be a continuous, encircling edge that is fixedly connected to the second elastic fabric layer 3 and the first elastic fabric layer 1 via the fixing part 5, or it can be partially fixed at one or more locations, allowing for various optional process methods. The remaining structure of this embodiment is the same as that of embodiment 3, and will not be described again here.

[0047] Example 5 like Figure 8As shown, this embodiment provides an elastic electrode pack structure 500. Based on Embodiment 1, the conductive tabs 41 of the conductive sheet 4 are bent and extended into the space between the second elastic fabric layer 3 and the first elastic fabric layer 1, thereby improving the overall aesthetics of the garment. Specifically, in this embodiment, the second elastic fabric layer 3 has elastic layer perforations 31, through which the conductive tabs 41 pass, extending between the elastic buffer layer 2 and the first elastic fabric layer 1. The first elastic fabric layer 1 may have wire holes for the conductive wires 7 to pass through, allowing the conductive wires 7 to be arranged on either side of the first elastic fabric layer 1. The remaining structures of this embodiment are the same as in Embodiment 1, and will not be described again here.

[0048] Example 6 like Figure 9 As shown, this embodiment provides an elastic electrode pack structure 600. This embodiment is a variant of the structure of embodiment 5. The difference between this embodiment and embodiment 5 is that the second elastic fabric layer 3 in this embodiment does not have elastic layer perforations 31.

[0049] In this embodiment, the conductive sheet 4 extends from the surface of the second elastic fabric layer 3 to the edge of the fabric of the second elastic fabric layer 3, and continues to bend inward from the edge of the fabric of the second elastic fabric layer 3, extending inward along the back side of the second elastic fabric layer 3 until the conductive ear 41 extends into the space between the second elastic fabric layer 3 and the first elastic fabric layer 1. Specifically, the conductive ear 41 extends between the elastic buffer layer 2 and the first elastic fabric layer 1, thereby further optimizing the orientation and concealment effect of the connector device 8 in the elastic electrode overlay structure, and improving the overall aesthetics of the garment. The remaining structure of this embodiment is the same as that of embodiment 5, and will not be described again here.

[0050] Example 7 like Figure 10 As shown, this embodiment provides an elastic electrode pack structure 700. Based on Embodiment 1, the conductive ear 41 of the conductive sheet 4 is bent and extended into the space between the second elastic fabric layer 3 and the first elastic fabric layer 1, thereby improving the overall aesthetics of the garment. In this embodiment, the second elastic fabric layer 3 has an elastic layer perforation 31, through which the conductive ear 41 passes, extending between the second elastic fabric layer 3 and the elastic buffer layer 2. A connector device 8 is disposed on the conductive ear 41, and a conductive wire 7 is connected to the connector device 8. The conductive wire 7 can bypass the elastic buffer layer 2 and then pass through the space between the second elastic fabric layer 3 and the first elastic fabric layer 1. Alternatively, the conductive wire 7 can pass through the elastic buffer layer 2 and then pass through the space between the second elastic fabric layer 3 and the first elastic fabric layer 1, as shown. Figure 10The conductive wire 7a is shown in the diagram. Alternatively, the first elastic fabric layer 1 may have holes for the conductive wire 7 to pass through. The conductive wire 7 can pass through the elastic buffer layer 2 and the first elastic fabric layer 1 in sequence before exiting, as shown in the diagram. Figure 10 As shown in the conductive line 7b, the conductive line 7 can be arranged in various ways to meet the needs of various scenarios. The rest of the structure in this embodiment is the same as that in embodiment 1, and will not be described again here.

[0051] Example 8 like Figure 11 As shown, this embodiment is a variant of the structure of embodiment 7. The difference between this embodiment and embodiment 7 is that the second elastic fabric layer 3 in this embodiment does not have elastic layer perforations 31.

[0052] In this embodiment, the conductive sheet 4 extends from the surface of the second elastic fabric layer 3 to the fabric edge of the second elastic fabric layer 3, and continues to bend inward from the fabric edge of the second elastic fabric layer 3, extending along the back side of the second elastic fabric layer 3 until the conductive ear 41 extends into the space between the second elastic fabric layer 3 and the first elastic fabric layer 1. Specifically, the conductive ear 41 extends between the second elastic fabric layer 3 and the elastic buffer layer 2, thereby further optimizing the orientation and concealment effect of the connector device 8 in the elastic electrode overlay structure, and improving the overall aesthetics of the garment. The remaining structure of this embodiment is the same as that of embodiment 7, and will not be described again here.

[0053] Example 9 like Figures 12-13 As shown, this embodiment is a variant based on the structure of Embodiment 1. In this embodiment, the conductive wire 7 and the conductive sheet 4 are connected by a connector device 13. The connector device 13 is the same as the connector device 8 in the previous embodiment, and the connector device 13 is disposed on the main body of the conductive sheet 4. In this embodiment, an insulating sheet 14 is further included. The insulating sheet 14 can be an adhesive or non-adhesive insulating sheet, which is bonded and fixed to the conductive sheet 4 by hot-melt adhesive film hot pressing, adhesive bonding or other methods, covering the surface of the connector device 13. In addition to its insulating function, the insulating sheet 14 can also protect the connector device 13, preventing the connection position of the conductive wire 7 and the connector device 13 from being touched and damaged; in addition, the insulating sheet 14 can also provide waterproofing.

[0054] like Figure 13 As shown, the projected area of ​​the insulating sheet 14 in the bonding direction is greater than the projected area of ​​the exposed conductive part of the connector device 13; preferably, the projected area of ​​the insulating sheet 14 is more than 5% larger than the projected area of ​​the exposed conductive part of the connector device 13, to ensure that the insulating sheet 14 reliably covers the exposed conductive part of the connector device 13, and to avoid poor insulation, protection or waterproofing effect due to insufficient area of ​​the insulating sheet 14.

[0055] It should be noted that the shape and size of the elastic electrode pack structure are not limited in any of the above embodiments. The fixing method between the conductive sheet 4 and the second elastic fabric layer 3 in the elastic electrode pack structure can be one or more combinations of sewing, hot-pressing adhesive film bonding, and glue adhesion. Alternatively, one or more layers of other materials can be added between the conductive sheet 4 and the second elastic fabric layer 3 to ensure the final fixing effect. The exit position of the conductive wire 7 in each embodiment can be implemented in various ways, and the specific method can be determined according to the appearance design requirements and stitching needs of the garment. Different technical features in the above embodiments can be combined with each other to form new implementation methods without conflict, and this invention will not list them all.

[0056] This invention also provides an intelligent garment based on electrical stimulation. The intelligent garment is a wearable textile product, comprising a garment body and an elastic electrode pack structure as described in any of the foregoing embodiments, disposed on the garment body. Further, the intelligent garment may also include a functional module, which is electrically connected to a conductive sheet 4 (i.e., an electrical stimulation output electrode) in the elastic electrode pack structure via a conductive wire 7. The functional module possesses at least an electrical stimulation function, which can be one or more of EMS, NMES, TENS, and IFT electrical stimulation functions, and has multiple electrical stimulation modes. Each mode, through different frequencies and waveform parameters, achieves different physiological effects such as muscle strengthening, nerve analgesia, and deep tissue relaxation. In addition, the functional module may optionally be configured with non-electrical stimulation additional functions, which can be one or more of heating, ECG acquisition, and EMG electromyography acquisition functions, to meet diverse physiological monitoring and physiotherapy needs.

[0057] Although the invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the invention without departing from the spirit and scope of the invention as defined in the appended claims, all of which shall be within the scope of protection of the invention.
