Description

Conductive devices for smart textiles Technical Field

[0001] This invention relates to a smart textile conductive device, specifically a conductive device that utilizes ultrasonic bonding technology to integrate an electric shock sheet, a metal conductive elastic wire, and a conductive connecting sheet into a single unit to form an electrically conductive device. This device is suitable for application in smart flexible fabric structures, allowing the fabric to form an electrical connection with fasteners and a detachable controller mounted on the fabric through the conductive device. Prior Technology

[0002] In recent years, the smart textile industry has developed rapidly, especially smart wearable textiles. Smart wearable textiles integrate the innovative technology of "textileizing electronic components" to enable textiles to meet the interactive functions expected by wearers, including the acquisition of internal body signals, reminders of the external environment, and the provision of external information.

[0003] Known smart wearable textiles refer to textiles with conductive wires and electronic sensing devices electrically connected to the conductive wires. However, the conductive wires conventionally laid on smart textiles are usually made through sewing, conductive adhesive or welding. However, the above conventional methods are prone to breakage, poor contact or structural aging due to bending, stretching or washing of the conductive wires. Summary of the Invention

[0004] The purpose of this invention is to provide a structural design that uses ultrasonic bonding to form a stable conductive path in fabric, thereby improving the bonding strength and electrical stability of conductive components in smart textiles.

[0005] This invention provides a conductive device for smart textiles, comprising: an electro-dispatch sheet woven from conductive fibers; a metal conductive elastic thread woven from metal conductive threads to possess elasticity; and a conductive connecting sheet woven from metal conductive fibers and formed into a sheet shape. The metal conductive elastic thread is layered between the electro-dispatch sheet and the conductive connecting sheet, and the electro-dispatch sheet and the conductive connecting sheet are bonded together to fix the metal conductive elastic thread between them. Accordingly, this invention uses ultrasonic bonding to fix the metal conductive elastic thread between the electro-dispatch sheet and the conductive connecting sheet to form a conductive device. This conductive device can be disposed in smart fabric, allowing the fabric to connect to the electro-dispatch sheet through the metal conductive elastic thread, and to form an electrical connection with a detachable controller via fasteners, creating a stable conductive path within the fabric, while simultaneously improving the bonding strength and electrical stability of conductive components in smart textiles.

[0007] In one embodiment of this invention, the metal conductive wire can be made of stainless steel wire as the substrate, and a conductive material coating is applied to its surface to form the metal conductive wire.

[0008] In one embodiment of this invention, the conductive connecting piece can be an SS12 metal conductive fiber sheet.

[0009] In one embodiment of this invention, the SS12 metal conductive fiber sheet can be a double-sided knitted fabric 30 / 70.

Implementation

[0012] To facilitate understanding of this invention, it is described in detail below with reference to the accompanying drawings and embodiments. The drawings show only a portion of the embodiments of this invention, not all of them. This invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this invention. Other embodiments obtained by those skilled in the art through simple modifications or equivalent creations based on the embodiments in this invention are all within the scope of protection of this invention.

[0013] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for descriptive purposes only and is not intended to be limiting of the invention.

[0014] As shown in Figures 1 and 2, this invention provides a method for manufacturing a conductive device for smart textiles, comprising: S1. An electric shock plate 10 is formed by weaving conductive fibers; S2. An elastic metal conductive wire 20 is formed by braiding metal conductive wires; S3, a conductive connecting piece 30 is formed by weaving metal conductive fibers; and S4. The electric shock piece 10, the metal conductive elastic wire 20 and the conductive connecting piece 30 are stacked and then bonded together by ultrasonic pressing, so that the metal conductive elastic wire 20 is fixed between the electric shock piece 10 and the conductive connecting piece 30.

[0015] The electric shock pad 10 is preferably woven from Ne30 / 2, 40 / 60 SS / PE yarn and Ne9 / 1 yarn; and both the warp and weft directions of the electric shock pad 10 are woven using the Ne30 / 2, 40 / 60 SS / PE yarn, while the warp direction of the back of the electric shock pad 10 is woven using Ne9 / 1 yarn. More specifically, the electric shock pad 10 can be made of T17 webbing, which is a high-strength nylon webbing with excellent tensile strength, abrasion resistance, and UV resistance.

[0016] The Ne30 / 2 yarn is a fine yarn made of two single yarns of 30 strands of British cotton count (Ne30). The joint structure gives it higher strength, uniformity, and better anti-pilling characteristics. The "Ne30 / 2" represents the count of British cotton; the "30" refers to the count of single yarn (the higher the count, the smaller, 30s is medium to fine); the " / 2" represents the two-strand line, which is two 30-branch yarns. Because it is a double strand (ply yarn), its physical characteristics are higher than the strength of single yarn, more uniform lines and stems, and a tighter and fuller hand feel. Often used in knitting clothes, making T-shirts, casual knitted shirts, with a comfortable skin-friendly feel. Commonly applied to bed sheets, duvet covers, especially high-strength and high-density bedding, such as Tencel or Khmer content products. For industrial applications it can be used for certain woven or sewing threads that require certain strong requirements. In terms of material combination, it can be made from 100% cotton, polyester-cotton blends, and synthetic fibers (such as celestial silk) and has a wide range of applications. Compared to single-strand yarns, Ne30 / 2 yarns perform better in strength and surface flatness due to their strand number structure factors.

[0017] The metal conductive wire is treated with a conductive material coating on its surface using stainless steel metal wire as a substrate to form a metal conductive wire that can conduct current, and then braided to form an elastic metal conductive elastic wire 20;

[0018] 40 / 60 SS / PET yarn is a blend of 40% artificial cotton (Spun Silk or Spun Rayon, SS) and 60% polyester fiber (Polyethylene Terephthalate, PET). This type of blended yarn combines the softness and skin-friendly properties of artificial cotton with the high strength, wear resistance and dimensional stability of PET and is widely used in clothing and fabrics. Its composition: 40% SS (commonly referred to as artificial cotton / cotton) and 60% PET (polyester fiber). Among them, SS brings skin-friendly, soft-touch comfort;PET provides high strength, anti-wrinkle and stable durability. The fineness is usually calculated in terms of the number of branches (S) (for example, 40 branches represents 40S), the larger the smaller the value.

[0019] Ne9 / 1 yarn (9-count single-ply yarn) is a coarser yarn specification, typically used in textiles requiring a certain thickness, strength, or rugged texture. In the British count (Ne) system, the smaller the number, the coarser the yarn. 9-count yarn is considered a coarse yarn and is commonly used in canvas, muslin, denim, thick T-shirts, knitted fabrics, decorative fabrics, and home textiles.

[0020] The conductive connector 30 can be made of SS12 metal conductive fiber sheet; for example, the SS12 metal conductive fiber sheet can be double-knitted fabric 30 / 70. More specifically, SS12 metal conductive fiber sheet is a composite material combining the conductivity of metal and the flexibility of fiber, usually made of a blend of metal wires (such as stainless steel) and traditional fibers. This type of material has excellent electromagnetic wave protection and antistatic effect, making it suitable as an EMI electromagnetic wave shielding component for wearable technology, antistatic work clothes, or IT devices (mobile phones, laptops). Its key characteristics include: highly conductive metallic properties, which can effectively conduct current and eliminate static electricity; fiber properties that make it flexible, suitable for sewing or weaving, and possessing the strength of metal.

[0021] The 30 / 70 knitted fabric typically refers to a knitted fabric blended from 30% component A and 70% component B. Common combinations include 30% cotton / 70% polyester (durable and moisture-wicking), 30% Tencel / 70% polyester (comfortable and durable), or 30% cotton / 70% wool (warm and high weight). This type of fabric often offers high comfort, elasticity, and specific functionalities, making it suitable for T-shirts, sportswear, hoodies, or high-end apparel.

[0022] Common types and characteristics of 30 / 70 knitted fabrics are as follows:

[0023] 30% Cotton + 70% Polyester: Commonly found in French Terry, combining the comfort of cotton with the durability of polyester, suitable for making sportswear, loungewear, and hoodies.

[0024] 30% Tencel + 70% Polyester: Combining the skin-friendly properties of Tencel with the stiffness of polyester, it is commonly found in single-knit sweaters.

[0025] 30% Cotton + 70% Wool: High-grammage fabric (e.g., 475 grams), with warm properties, suitable for high-end wool garments.

[0026] 30% moisture-wicking yarn + 70% graphene yarn: Functional jacquard knitted fabric that utilizes the properties of graphene for heat retention while also providing temperature regulation and sweat-wicking functions.

[0027] These fabrics are usually made of circular knitting, which has good elasticity and breathability.

[0028] As shown in Figures 2 and 3, after the aforementioned electric shock piece 10, metal conductive elastic wire 20 and conductive connecting piece 30 are manufactured, they are stacked and then bonded together by ultrasonic pressing. This fixes the metal conductive elastic wire 20 between the electric shock piece 10 and the conductive connecting piece 30. At the same time, the metal conductive elastic wire 20, the conductive connecting piece 30 and the electric shock piece 10 form an electrical conduction path with multiple metal fiber contacts in the pressing area, thereby constituting a conductive device.

[0029] In practical applications, the conductive device of this invention can be configured in smart fabric 40, allowing the fabric 40 to be connected to the electrostimulation pad 10 via the metal conductive elastic wire 20. An electrical connection is formed between the pad and a detachable controller (not shown) via fasteners disposed on the fabric. Decorative adhesive 50 can be applied to the surfaces of the fasteners and the detachable controller for concealment and decoration. When powered on, the electrostimulation pad 10 can provide, for example, heart rate detection, transmission to the controller, output of digitized data, and EMS electrical stimulation therapy, among other related applications.

[0030] The embodiments described above are merely preferred embodiments of this invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this invention. It should be noted that those skilled in the art can make various changes and modifications without departing from the inventive concept, and these all fall within the protection scope of this invention.
