Abstract

The invention discloses a flexible stretchable and washable conductive connecting piece. The flexible stretchable and washable conductive connecting piece is a composite conductive connecting piece formed by combination of a conductive material and a non-conductive material, the conductive material and the non-conductive material are simultaneously stretched and reset, and the electrical property remains unchanged. The conductive material and the non-conductive material are processed into the conductive connecting piece in the form of a fabric through a combined weaving process according to a wire arranging method, or the conductive connecting piece in the form of the fabric is sealed in an elastic base material made of the non-conductive material to fabricate the composite conductive connecting piece, or the conductive material is directly buried in the elastic base material to fabricate the composite conductive connecting piece. The flexible stretchable and washable conductive connecting piece has the advantages of good flexibility, wash resistance and excellent fatigue durability, and can be stretched substantially, the cyclic load and a resistance value after washing are small in change, the electric signal transmission is stable and reliable, good adhesion to the surface of a human body can be achieved, and the flexible stretchable and washable conductive connecting piece can replace a metal wire and a printed circuit to be applied to intelligent clothes and intelligent wearable devices.

[0028] In order to make the present invention more apparent and comprehensible, preferred embodiments are hereby described in detail as follows.

[0029] This embodiment provides a flexible, stretchable and washable conductive connector, which can be made into a flexible, stretchable and washable conductive connector through material selection, structural design and composite effect, which can be applied to smart clothing instead of metal wires and printed circuits. and smart wearable devices.

[0030] figure 1 Schematic diagram of the structure of a columnar conductive connector made of double helix-arranged conductive materials sealed in an elastic matrix by composite processing. The conductive materials 101 are arranged in a double helix, and the elastic substrate 102 is cylindrical and wrapped outside the conductive materials 101 .

The conductive material 103 is arranged in the elastic base body 104 in a wave shape, and the elastic base body 104 is in a film shape and covers the outside of the conductive material 103 .

[0032] figure 1 and figure 2 The shown conductive connector is a two-component polymer matrix composite material. The conductive materials 101 and 103 provide good electrical conductivity, and the regular shape arrangement is used to give them the ability to stretch and deform. The polymer elastic matrix provides good stretchability. Recovery, washability and fatigue resistance.

[0033] The above-mentioned conductive materials 101 and 103 may be intrinsically conductive polymer materials such as polyaniline, polythiophene, and polypyrrole, or filled with metal powders such as gold and silver, or carbon-based polymers such as carbon black and graphite. The composite conductive polymer material is made of; metal wires such as copper wire and silver wire, or conductive yarn such as silver-plated, copper-plated or copper-nickel-plated can also be used. The above-mentioned elastic substrates 102 and 104 may be elastic high molecular polymers such as PDMS, PU, and SBS.

[0034] like image 3 As shown, in the present invention, the form of the conductive material is not limited to the above-mentioned several embodiments, and can also be image 3 The zigzag, zigzag, sinusoidal and wavy shapes shown, etc., can be extended or flexed.

[0035] Figure 4 A schematic diagram of the structure of the conductive connector in the form of a fabric made by combining the conductive material and the non-conductive material by the weft-jersey knitting process. The conductive wire 201 made of conductive material and the non-conductive wire 202 made of non-conductive material are arranged in the form of coils in the fabric. The conductive wire 201 and the non-conductive wire 202 can be stretched and flexed synchronously.

[0036] Figure 5 A schematic diagram of the structure of a conductive connector in the form of a fabric woven by a combination of a conductive material and a linear non-conductive material by a plain weaving process. The conductive threads 203 made of conductive materials are arranged in parallel in the fabric, and the non-conductive threads 204 made of non-conductive materials are interwoven in the fabric. The wire 204 can be stretched and flexed simultaneously. Among them, the conductive wire 203 can be made of intrinsic conductive polymer or metal powder, conductive filament or yarn made of carbon-based composite conductive polymer, or metal conductive wire such as copper wire and silver wire, or silver-plated Or metal-plated conductive yarns such as copper-nickel plating, or conductive filaments or conductive yarns combined with conductive materials. Wherein, the non-conductive thread 204 may be one or a combination of textile yarns such as polyester, nylon, spandex, cotton, and regenerated cellulose fibers.

[0037] Figure 4 and Figure 5 The shown conductive connector is a fabric-shaped conductive connector, and the conductive threads 201, 203 and the non-conductive threads 202, 204 are interwoven into a fabric through a weaving process. The conductive yarn is treated with water repellency or washing resistance, or the fabric can be combined with an elastic matrix to obtain good washing resistance.

[0038] Image 6 The relationship curve between the resistance change of the conductive connector and the tensile strain is shown. In the strain range of 0-100%, the resistance change can be controlled within 2%.

[0039] Figure 7 The relationship curve between the resistance change of the conductive connector and the number of cyclic loadings is shown. When the strain is 0-50% cyclic loading, the loading number is 5000 times, and the resistance change can be controlled within 0.5%.

[0040] Depend on Image 6 and Figure 7 It can be seen that under the premise of being stretchable, the conductive connector of the present invention can also maintain stable electrical properties, and is an excellent choice for preparing smart wearable products, especially flexible and washable smart wearable products.
