[0035] The present invention also provides a power-powered garment, which includes the power-powered fabric of the present invention.

[0036] The beneficial effects of this invention are as follows:

[0037] 1. The power supply fabric of the present invention uses positively charged yarns, negatively charged yarns, and functional yarns as warp and weft, respectively. The storage of induced charge and the conduction of induced current are achieved through the mutual contact and friction between the yarns in the vertical or horizontal directions, thus enabling external power supply. Furthermore, the power supply effect can be achieved in a single layer of fabric, eliminating the need for other energy storage or power supply devices and multi-layer composite fabric structures, making the fabric itself lighter, more comfortable, and more breathable. In addition, since the power supply fabric of the present invention is a single layer, it avoids the material fatigue that occurs in multi-layer fabrics after long-term use, thus preventing the problems of interlayer slippage or separation and performance degradation. The functional yarns can provide additional functions on top of external power supply, such as moisture absorption, temperature sensing, pressure sensing, and light sensing.

[0038] 2. The power supply fabric of the present invention, through the structural design of composite positively charged yarn including a first conductive core layer and a first conductive sheath covering the first conductive core layer, wherein the conductivity of the first conductive sheath is greater than that of the first conductive core layer; and composite negatively charged yarn including a second conductive core layer and a second conductive sheath covering the second conductive core layer, wherein the conductivity of the second conductive core layer is greater than that of the second conductive sheath, enables induced static electricity to be generated through friction between the composite positively charged yarn, the composite negatively charged yarn, and the functional yarn. In the process, there are four states: yarn compression to the limit (first state), yarn release (second state), yarn release to the limit (third state), and yarn compression (fourth state). The fabric cycles through these four states during the friction process.In the first state (I), the composite positively charged yarn and the composite negatively charged yarn begin to approach, contact, and deform under pressure as the fabric is subjected to a vertical load. This process causes the first conductive cladding and the second conductive cladding of the composite positively charged yarn to become internally polarized due to frictional contact, generating equal amounts of positive and negative charges on their respective surfaces, forming an equipotential body pair in a positive and negative charge dipole state. Subsequently, in the second state (II), when the pressure load on the fabric is removed, elastic recovery occurs between the composite positively charged and negatively charged yarns in the fabric. The first conductive core layer and the second conductive core layer, which are adjacent to the first conductive cladding layer and the second conductive cladding layer of the composite positively charged yarn, respectively, are another pair of induced pairs under study. These serve as the positive and negative terminals of an external circuit and can be connected to the positive and negative terminals of a power supply device to form an independent single-electrode series-connected induced power supply path. In the second state II, the separation of the two pairs of induced pairs disrupts the equipotential environment of the two pairs in equilibrium, resulting in internal polarization. As the object of study, the first conductive core layer of the composite positively charged yarn, due to... Electrostatic induction on the surfaces of adjacent positively charged conductive cladding layers gradually generates and accumulates negative charges on their surfaces, and similarly, positive charges gradually accumulate and accumulate on the surface of the second conductive core layer. This generates a positive induced current flowing towards the composite negatively charged second conductive core layer (in the same direction as the positive charge flow). As the fabric fully recovers its elasticity after unloading, the internal polarization of the inductive electrode pairs in the first conductive core layer and the second conductive core layer of the composite positively charged yarn, as well as the charge density of their respective inductive dipole layers, reach their maximum. At this point, they exhibit electrostatic shielding and are in a stable transition from external power supply to intrinsic energy storage. In the second state (II) and the third state (III), the external devices are powered or charged once. When the fabric is subjected to a secondary load in the same vertical direction, the composite positive and negative polarity yarns approach each other again, come into contact, rub and squeeze each other. That is, in the fourth state (IV), the induction electrode pairs in the electrostatic shielding stable transition state approach each other again and come into contact with each other, causing the induction electrode pairs in the maximum electrostatic coupling equipotential to be repolarized. Due to the principle of electrostatic neutralization, a reverse induction current is generated and flows to the first conductive core, realizing the energy storage and collection of the intrinsic body of the power-generating clothing.

[0039] 3. The power supply fabric of the present invention comprises a first conductive core layer made of nylon and a first conductive cladding layer made of silver; a second conductive cladding layer made of polydimethylsiloxane and a second conductive core layer made of carbon nanotubes. This material configuration enables the storage and dissipation of electrostatic triboelectric charge through inter-yarn contact friction, thereby achieving external power supply. Furthermore, the silver in the first cladding layer provides the fabric with good antibacterial properties; the polydimethylsiloxane in the second cladding layer has good hydrophobicity, giving the power supply fabric good waterproof performance.

[0040] 4. The power supply fabric of the present invention comprises functional yarns including cotton yarn, spandex, silk fiber, viscose fiber, polyester fiber, modal fiber, lyocell fiber, polyester, acrylic fiber, carbon fiber, cellulose fiber, wool fiber, light-sensitive fiber, temperature-sensitive fiber, and piezoelectric fiber or blended yarns thereof, so that the power supply fabric can have various additional functions provided by the functional yarns, including moisture absorption, antibacterial, light-sensitive, temperature-sensitive, piezoelectric and other functions.

[0041] 5. The power supply fabric of the present invention comprises a blended yarn of cotton yarn and polyester fiber yarn. The cotton yarn and polyester fiber yarn enable rapid wicking, conduction and diffusion of moisture, as well as surface evaporation, thereby giving the power supply fabric of the present invention good moisture absorption and perspiration wicking function and good wearing thermal comfort.

[0042] 6. The power supply fabric of the present invention, through the power supply fabric to... Fabrics with flattened weave, Weft-ply plain weave fabric, Fabrics with flattened weave, Weft-ply plain weave fabric, Square flat fabric or Plain weave fabrics combine positively charged, negatively charged, and functional yarns to form a power-conducting fabric, allowing for flexibility in structural choices to meet diverse structural, power supply, and functional requirements. Furthermore, these plain weave fabrics achieve a balance between lightweight breathability and excellent electrical conductivity.

[0043] 7. The power supply fabric of the present invention, wherein the power supply fabric is... Variational weft plain weave fabric. The variable weft plain weave fabric is a weft-faced fabric located in the 7th to 9th structural phases. The longer weft float of the variable weft plain weave fabric not only allows for a wider range of apparel design effects, but also the rich and varied warp and weft weave points enable greater design freedom in the connection and contact of the positive and negative charge yarn sensing electrodes in the warp and weft system, allowing for the construction of different vertical and horizontal series and parallel electrode combinations, resulting in higher energy and power output density.

[0044] 8. The power-powered clothing provided by this invention includes the power-powered fabric of this invention. Using positively charged yarns, negatively charged yarns, and functional yarns as warp and weft respectively, electrostatic triboelectric charge is stored and discharged through contact friction between the yarns, achieving external power supply. Furthermore, the power supply effect can be achieved in a single layer of fabric, eliminating the need for other energy storage or power supply devices and multi-layer composite fabric structures, making the fabric itself lighter, more comfortable, and more breathable. In addition, since the power-powered fabric of this invention is a single-layer fabric, it avoids the material fatigue that occurs in multi-layer fabrics after long-term use, thus preventing interlayer slippage or separation and performance degradation. The functional yarns can provide additional functions on top of external power supply, such as moisture absorption, temperature sensing, pressure sensing, and light sensing.

[0084] about Electrostatic energy storage in resilient fabrics and the process of supplying or charging power to devices under test, refer to Figure 8 . The fabric employs a contact-separation single-electrode series operation mode with a horizontal warp structure. The process includes four states: yarn compression to its limit (first state I), yarn release (second state II), yarn release to its limit (third state III), and yarn compression (fourth state IV). In these four states, the conductive core layers of the composite positive and negative charge yarns in the cyclic fabric achieve electrostatic energy storage and power supply or charging through contact friction. Specifically, in the first state I, the composite positive charge yarn 100 and composite negative charge yarn 200 are compressed and deformed, coming into contact with each other and generating induced charges. The first conductive cladding layer 110 of the composite positive charge yarn 100 accumulates positive charges to form a positive charge dipole layer, and the second conductive cladding layer 210 of the composite negative charge yarn 200 accumulates negative charges to form a negative charge dipole layer. At this time, the first conductive core layer 120 of the composite positive charge yarn 100 and the second conductive core layer 220 of the composite negative charge yarn 200 are equipotential bodies. In the second state II, the compression force is removed, and the compression load is released. The yarn begins to recover its elasticity, changing from state I to state III. In this second state II, the first conductive core layer 120 of the composite positively charged yarn 100 generates a corresponding induced negative charge due to the induction of the positively charged dipole layer on the surface of its conductive cladding 110. Simultaneously, the second conductive core layer 220 of the composite negatively charged yarn 200 generates a corresponding induced positive charge due to the induction of the negatively charged dipole layer on the surface of its conductive cladding 210. The first conductive core layer 120 and the second conductive core layer 220 are respectively connected to the positive and negative terminals of the device to be powered, forming a connected circuit. In state II, an induced electromotive force and a corresponding positive induced current i are formed between the first conductive core layer 120 and the second conductive core layer 220, enabling the power supply fabric to supply power or charge the device to be powered. In state III, the yarn is released to its limit, and the charge migration in state II reaches saturation. The first conductive core layer 120 and the second conductive core layer 220 form a pair of corresponding stable equipotential bodies. At the same time, the composite positively charged yarn 100 and the composite negatively charged yarn 200 also form another pair of stable equipotential bodies due to their greater distance. The spacing provides electrostatic shielding and does not generate induced current. In the fourth state (IV), the yarns are compressed again, changing from the third state (III) to the first state (I). The composite positively charged yarn 100 and the composite negatively charged yarn 200 approach and contact each other again, thereby repolarizing their internal structures and disrupting the stable equipotential electrostatic coupling layer in the third state (III). This generates charge migration and induced electromotive force, forming a reverse induced current i of positive charge flowing from the second conductive core layer 220 to the first conductive core layer 120 in the intrinsic body of the power-generating garment, thus realizing the intrinsic electrical energy storage of the power-generating garment. Through the load-release-reload-rerelease cycle, the wearable power-generating garment can charge and power external devices and recharge its own energy storage.

[0131] Example 7

[0132] refer to Figure 7 and Figure 8 as well as Figure 12 This embodiment provides a power supply fabric, which is a single-layer plain weave fabric. Specifically, the power supply fabric is...

The linear density of positively charged yarns ranges from 9.85 dtex to 2.96 tex; the linear density of negatively charged yarns ranges from 10.29 dtex to 15.4 tex.

[0139] In this embodiment, The warp density of the variable weft plain weave fabric is 242 threads / 10cm. The weft density of the variable weft plain weave fabric is 224 threads / 10cm.

The linear density of functional yarn 300 is 32 dtex.

[0140] about For the electrostatic energy storage and power supply or charging process of the device to be powered by the variable weft plain weave fabric, please refer to Example 1, and Figure 12 The difference from Example 1 is that this example includes both the induced electromotive force and current generated by the frictional contact and arrangement of positive and negative charged yarns in the vertical direction, and the induced electromotive force and current generated by the frictional contact and arrangement of positive and negative charged yarns in the horizontal direction within the same weft width unit; wherein, when the fabric is subjected to a horizontal bidirectional compression load, the two composite negative charged yarns 200 (the first negative charged warp and the third negative charged warp) with lower warp linear density move inward and contract, gradually coming into contact with and rubbing against the positive charged yarn 100 (the second positive charged warp) between them. Until the extreme state of compression, during the process of reaching the extreme state of compression in the warp and weft space, the difference in the geometric structure of the fabric's warp and weft is utilized to cause the positively charged yarn 100 to undergo elastic deformation and be lifted upwards by the contact and compression load of the two adjacent composite negatively charged yarns 200 during the inward contraction of the warp and weft. It then moves to contact and compress with the negatively charged weft yarn 200' until it reaches the maximum extreme state, forming a "reverse Y-shaped" four independent induction working electrodes in the horizontal and vertical directions. This is a composite form of horizontal induction dual electrode pairs in parallel and vertical independent single electrode pairs in series. Figure 12(In the dashed box). Specifically: The entire process includes six states: yarn compression to the limit (first state I), yarn release (second state II and third state), yarn release to the limit (fourth state IV), and yarn compression (fifth state V and sixth state VI). This simulates the low-frequency cyclical motion of the fabric under the repeated stretching load of the limbs during human running exercise. This power-generating clothing completes the process of storing and charging its own electrical energy and charging external devices. In the first state I, the composite positively charged yarn 100 and the composite negatively charged yarn 200 are subjected to a horizontal bidirectional compression load. The positive and negatively charged yarns approach each other and generate internal polarization. The first conductive cladding 110 of the composite positively charged yarn 100 and the second conductive cladding 210 of the composite negatively charged yarn 200, which are the objects of study for induced electric couples, respectively accumulate positive and negative charges and form an equilibrium potential body in which induced polarized positive and negative charge layers coexist. At the same time, the conductive cladding of the weft composite negatively charged yarn 200' is subjected to electrostatic coupling-induced polarization due to the upward displacement and approach of the composite positively charged yarn 100, and an induced dipole layer with an equal amount of negative charge is generated on the surface. At the same time, an equal amount of positive charge is also accumulated again in the first conductive cladding of the composite positively charged yarn 100. The subsequent yarn release process includes two states, the second state II and the third state III, as well as the final ultimate state, the fourth state IV. During yarn release, when the squeezing pressure is removed and the squeezing load is released, the fabric and yarn begin to elastically recover and stretch to both sides, changing from the first state I to the fourth state IV. In the elastic recovery stretching process of the second state II, the first step is the separation of the composite positively charged yarn 100 and the weft composite negatively charged yarn 200' at the top contact. As the research object, the conductive core layers of the first conductive core layer 120 and the weft composite negatively charged yarn 200' are respectively connected to the positive and negative terminals of the device to be powered to form a conductive external circuit. At this time, the separation displacement process causes the conductive core layers of the first conductive core layer 120 and the weft composite negatively charged yarn 200' to generate internal polarization, and positive and negative charges begin to migrate from them respectively, generating a corresponding positive induced current i, which flows from the positive terminal of the device to be powered to perform the first stage of local power supply and charging. This local power supply and charging process is provided by the series induction circuit of the independent single electrode pair in this stage.As the release process continues, the system transitions from state II to state III. The independent single-electrode pair series induction circuit, composed of the first conductive core layer 120 and the conductive core layer of the weft composite negatively charged yarn 200', gradually reaches its saturation limit. Meanwhile, at the other end, the composite positively charged yarn 100 gradually returns to its initial state and begins to contact and separate from the adjacent composite negatively charged yarn 200, polarizing with each other. The composite positively charged yarn 100, the first conductive core layer 120, and the second conductive core layer of the composite negatively charged yarn 200 experience positive and negative charge migration, respectively accumulating to form a negative dipole layer and a positive dipole layer. This generates a positive induced current i flowing from the first conductive core layer 120 of the composite positively charged yarn 100 to the conductive core layers of the two adjacent composite negatively charged yarns 200, forming a horizontal dual independent induction pair parallel operation induction circuit. This provides the remaining local second-stage power supply and charging to the device under test, until they completely separate from each other. In the initial natural state, a single complete power supply process for the device is formed by a combination of vertical series and horizontal parallel connections. In the fourth state IV, when the yarn is released to its limit, the charge migration in the second state II and the third state III reaches saturation. At this time, the first conductive core layer 120 and the second conductive core layer 220, the first conductive core layer 120 and the conductive core layer of the weft composite negatively charged yarn 200', the composite positively charged yarn 100 and the composite negatively charged yarn 200, and the composite positively charged yarn 100 and the weft composite negatively charged yarn 200' respectively form two pairs of independent and stable induced equipotential pairs. Due to the electrostatic shielding effect, no polarized induced current is generated in the extreme saturation state. When the yarn is subjected to the same compressive load again, the fabric is in the fifth state V and the sixth state VI, and then finally returns to the initial state, completing one cycle of power supply and charging of the external device and the intrinsic charge storage and charging of the fabric itself.In the fifth state V, the transition from the fourth state IV to the first state I occurs. The composite positively charged yarn 100 and the composite negatively charged yarn 200 are brought closer together again under load. The specific stages of this transition are the same as those from the first state I to the third state III. The difference is that during the transition from the fourth state IV to the first state I, the polarization of the induced pairs and the direction of the induced current are reversed. This includes the first stage of fabric release and stretching (fifth state V), where the first conductive core layer 120 of the composite positively charged yarn 100 flows into the horizontal double independent induced pair parallel induction circuit formed by the conductive core layers of the two adjacent composite negatively charged yarns 200, and the other independent first conductive core layer 120 and the weft composite negatively charged yarn 200'. The independent single-electrode pair series induction circuit, composed of conductive core layers, completes the local storage or charging of the intrinsic charge of the fabric itself; and finally, in the second stage of the remaining release to the ultimate saturation state (sixth state VI), the independent single-electrode pair series induction circuit formed by the contact and friction polarization of the conductive core layer 120 of the intermediate composite positively charged yarn 100 and the conductive core layer of the weft composite negatively charged yarn 200' in the state of being squeezed and pushed up again, generates an induced current that provides the subsequent continuous stage of intrinsic energy storage and charging of the fabric. The induction circuit current, which has two local stages in series and parallel form, flows in and out from the positive terminal of the external receiving device, respectively, realizing the complete bidirectional conversion of generating and charging external devices and supplying the fabric's own intrinsic energy storage.

[0141] The unique feature of this structure lies in the fact that when the fabric is subjected to horizontal bidirectional compression, the positive and negative charged yarns in the warp and weft directions come into contact with each other and become polarized to generate electrostatic induction. During the compression contact and release recovery process, a composite working mode of inverted Y-shaped four electrodes in series and parallel is formed by combining horizontal and vertical structures. This allows for greater design freedom in terms of energy density output and power enhancement, and can realize different combinations of series and parallel electrodes with vertical and horizontal structures to improve energy and power output density.

[0142] This embodiment The longer weft float of the variable weft plain weave fabric not only allows for a wider range of apparel design effects, but also the rich and varied warp and weft weave points enable greater design freedom in the connection and contact of the positive and negative charge yarn sensing electrodes in the warp and weft system, allowing for different vertical and horizontal series and parallel electrode combinations to achieve adjustable energy and power output density designs.

[0143] Example 8

[0144] This embodiment provides a power-generating garment, including any of the power-generating fabrics described in Embodiments 1-7 above. Static electricity is stored and discharged through friction between the yarns, allowing the fabric itself to store and discharge static electricity via friction, thus enabling external power supply. Furthermore, the power supply effect is achieved within a single layer of fabric, eliminating the need for other energy storage or power supply devices and multi-layer composite fabric structures, making the fabric itself lighter and more comfortable. In addition, since the power-generating fabric of this invention is a single-layer fabric, it avoids the material fatigue that occurs in multi-layer fabrics after long-term use, preventing interlayer slippage or separation that leads to performance degradation. Functional yarns can provide additional functions beyond external power supply, such as moisture absorption, temperature sensing, pressure sensing, and light sensing.
