Description

Technical Field

[0001] The present invention relates to the technical field of friction power generation, and more specifically, to a friction nano power generation fabric and application thereof. Background Art

[0002] Friction nanogenerator is a green and sustainable energy technology that converts mechanical energy into electrical energy based on friction electrification and electrostatic induction effects. Compared with electromagnetic induction power generation and piezoelectric power generation technology, friction nanogenerator has the advantages of high voltage, high conversion efficiency, light weight, small size, good flexibility, etc., and has shown great development potential in the field of wearable electronic devices.

[0003] In recent years, textile-based triboelectric nanogenerators have gradually become a research hotspot due to their soft and light characteristics. The triboelectric nanogenerator is usually prepared by forming a nanostructure on the surface of the fabric or using a multilayer structure. For example, by coating a uniform polymer film on a conductive silver cloth or evenly distributing nanoparticles on the surface of the fabric.

[0004] Although textile-based triboelectric nanogenerators have shown great potential in the fields of energy harvesting and self-powered sensors, most current textile triboelectric nanogenerators still have some limitations. For example, they usually require complex manufacturing processes and may suffer from performance degradation after long-term use.

[0005] In addition, some existing textile triboelectric nanogenerators may lack sufficient comfort and elasticity, which limits their application in wearable devices.

[0006] Therefore, to realize its commercial application, many problems in existing technologies need to be solved, including improving power generation efficiency, simplifying the preparation process, and enhancing the comfort, elasticity and breathability of the fabric. Summary of the invention

[0007] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a friction nano-power generation fabric with a simple structure, a simple preparation process, and good comfort, elasticity and breathability.

[0008] To achieve the above object, the present invention provides the following technical solutions: A friction nano-power generation fabric is formed by weaving friction power generation yarn and electrode yarn, wherein the friction power generation yarn is woven to form the front side of the fabric, and the electrode yarn is woven to form the back side of the fabric; the friction power generation yarn and the electrode yarn overlap each other; the diameter of the friction power generation yarn needs to be larger than that of the electrode yarn, and the friction power generation yarn covers the electrode yarn; the friction power generation yarn and the electrode yarn have different elasticities; when stretched by external force, the friction power generation yarn and the electrode yarn elastically produce different deformations, resulting in different displacements between the two, thereby generating friction power generation.

[0009] Furthermore, the friction-generating yarn is wool yarn, silk yarn, polyester yarn or polymer-coated yarn.

[0010] Furthermore, the electrode yarn is a copper wire, an aluminum wire, a stainless steel wire or a silver-plated conductive wire.

[0011] Furthermore, when the friction nano-electricity generating fabric is woven, the tension of the friction electric generating yarn and the electrode yarn is kept consistent.

[0012] Furthermore, when the friction nano-electricity generating fabric is used for textile feeding, the friction electric generating yarn is close to the needle back, and the electrode yarn is close to the needle hook.

[0013] Furthermore, wearable electronic devices can be made using the friction nano-power generation fabric of the present invention.

[0014] By adopting the above technical solution, the beneficial effects of the present invention are: Simple structure and simple preparation process: It is composed of triboelectric yarn and electrode yarn woven together, does not require complicated manufacturing process, and is easy to achieve commercialization and large-scale production.

[0015] One-piece molding: The friction-generating yarn and the electrode yarn are woven together into one piece, which improves production efficiency and product quality.

[0016] Excellent comfort: The friction-generating yarn can be made of natural fibers such as wool, silk, or polyester yarn, etc. It has good skin affinity and softness and is comfortable to wear.

[0017] Good breathability: The woven structure of the fabric allows air to circulate freely, keeping the skin dry and suitable for long-term wear.

[0018] High elasticity: The difference in elasticity between the triboelectric yarn and the electrode yarn enables the fabric to produce different deformations and displacements under the action of external force, thereby generating triboelectric power while maintaining the high elasticity of the fabric to adapt to various body movements.

[0019] Washability: The structure and material selection of the fabric make it resistant to washing, easy to clean and maintain, and extend its service life.

[0020] Applicable to the field of wearable electronic devices: It can provide electrical energy for electronic components, such as lighting LED lights, charging electronic devices, etc., providing a new energy solution for the development of wearable electronic devices.

[0021] Providing green, clean and environmentally friendly energy: Converting mechanical energy into electrical energy based on friction electrification and electrostatic induction effects is a green and sustainable energy technology that meets environmental protection requirements.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0030] like Figure 1 and Figure 2As shown, the friction nano-electricity fabric includes a friction electric yarn 1 and an electrode yarn 2. The friction nano-electricity fabric is woven by coils of the friction electric yarn 1 and the electrode yarn 2 overlapping each other. The friction electric yarn 1 and the electrode yarn 2 are located on the front and back of the fabric respectively. The diameter of the friction electric yarn 1 must be larger than that of the electrode yarn 2; the friction electric yarn 1 completely covers the electrode yarn 2.

[0031] All coils in the friction nano-electricity fabric are formed by overlapping two yarns, the friction electric yarn 1 and the electrode yarn 2, wherein the friction electric yarn 1 is exposed on the front side, as shown in FIG. Figure 1 As shown; the reverse side reveals the electrode yarn 2, as Figure 2 shown.

[0032] The frictional electric yarn 1 may be wool yarn, silk yarn, polyester yarn, synthetic yarn with a surface coated with a polymer, or the like.

[0033] The electrode yarn 2 is a metal wire or other textile yarn with conductive properties, and can be a copper wire, an aluminum wire, a stainless steel wire, a silver-plated conductive wire, or the like.

[0034] There is a certain difference in elasticity between the frictional power generation yarn 1 and the electrode yarn 2: the frictional power generation yarn 1 is made of textile yarn with good elasticity, and the electrode yarn 2 is made of metal wire with average elasticity.

[0035] When preparing the friction nano-electricity generating fabric, it is prepared by a flat knitting machine and other equipment. The friction generating yarn 1 and the electrode yarn 2 are fed into the knitting needles at the same time by a yarn guide 3, and are woven together into one piece. The yarn guide 3 has two vertically arranged yarn guide holes 301 and a yarn guide hole 302, wherein the yarn guide hole 301 is used for the electrode yarn 2 to pass through, and the yarn guide hole 302 is used for the friction generating yarn 1 to pass through. The yarn guide 3 can ensure that the two yarns can maintain the correct position when feeding the yarn, so that the two yarns can maintain a good covering relationship during the coil formation process.

[0036] During weaving, the tension of the triboelectric yarn 1 and the electrode yarn 2 must be kept consistent. During yarn feeding, the triboelectric yarn 1 is close to the needle back and the electrode yarn 2 is close to the needle hook.

[0037] When an external force stretches the friction nano-power generation fabric, due to the difference in elasticity between the friction power generation yarn 1 and the electrode yarn 2, the two yarns will produce different deformations and different displacements, thereby generating friction power generation.

[0038] Embodiment 1:

[0039] like Figure 3As shown, one end of the electronic component is connected to the electrode yarn 2, and the other end is grounded, and this mode becomes a single electrode mode. The friction nano power generation fabric in the single electrode mode can provide electrical energy for the electronic components, such as lighting up LED lights, charging electronic components, etc.

[0040] Embodiment 2:

[0041] like Figure 4 As shown, an electrode yarn 2 of a friction nano-power generation fabric is connected to each end of the electronic component to form a friction nano-generator in a dual-electrode mode. The two friction power generation yarns 1 of the two friction nano-power generation fabrics are textile yarns or polymer coated yarns with different dielectric properties, one is positively charged and the other is negatively charged. The two friction power generation yarns 1 are located opposite to each other. When the two friction power generation yarns 1 come into contact and separate under the action of an external force, electrons are transferred due to the friction electrification effect and electrostatic induction, thereby generating electrical energy to power the electronic components.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Common changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention should be included in the protection scope of the present invention.
