Description

Technical Field

[0001] This utility model relates to the field of clothing design technology, specifically to a self-generating intelligent garment for posture correction based on a triboelectric nanogenerator. Background Technology

[0002] Adolescents are in a critical period of growth and development. Prolonged incorrect sitting posture can lead to problems such as lumbar tilt and hunchback, which not only affect their physical development and physiological health but also their mental health. Currently, a variety of posture correction products have emerged on the market, but in actual use, they have revealed many limitations, such as limited applicability, inconvenience in wearing, and poor comfort, making it difficult to meet the widespread needs of adolescents.

[0003] Existing smart posture correction garments have limited design and development of the garment carrier itself, often opting for readily available, lightweight, and form-fitting ordinary clothing. However, besides providing real-time reminders and warnings from a posture monitoring and correction system, smart posture correction garments should possess the characteristics of traditional posture correction garments, passively correcting excessive posture deviations or maintaining good posture—requirements that ordinary clothing cannot meet. For example, LILI et al. used posture correction belts as wearable garment carriers, restricting the range of motion of the shoulders, chest, and waist through cross-linked restraints. These belts offer a strong sense of restraint, and the pressure on the shoulders increases with shoulder width, chest circumference, and upper arm circumference when worn by different body types. Excessive pressure can easily obstruct local blood flow, thus affecting blood circulation. Meanwhile, most wearable pressure sensors on the market rely on traditional batteries for power, which not only increases the weight and size of the device and reduces wearing comfort, but also limits its application in long-term, continuous monitoring. In view of the shortcomings of the existing technology, this utility model provides a self-generating posture correction integrated smart garment based on a triboelectric nanogenerator to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a self-generating, integrated smart garment for posture correction based on a triboelectric nanogenerator. This overcomes the limitations of traditional smart garments that rely on battery power, converting the mechanical energy generated by human activity into electrical energy to power the posture monitoring and correction system. This not only improves the comfort and portability of the garment but also ensures the continuous and stable operation of the posture monitoring and correction system, thereby enhancing the accuracy of monitoring.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a self-generating posture correction integrated smart garment based on a triboelectric nanogenerator, comprising a garment body, on which a TENG nanogenerator is mounted, and a flexible integrated circuit connected to the TENG nanogenerator is also mounted on the garment body. The flexible integrated circuit is connected to a flexible energy storage device, a pressure sensor module, and a vibration feedback device. The TENG nanogenerator includes:

[0006] PI-coated polyester yarn is polyester yarn formed by coating with PI solution.

[0007] Nylon yarn, woven together with PI-coated polyester yarn into a plain weave fabric layer;

[0008] The conductive polymer PPy layer and the plain weave fabric layer form the carrier of the conductive polymer PPy layer. PPy is used as the electrode material and is uniformly coated on the PI-coated polyester yarn and nylon yarn.

[0009] Nylon fabric, as the second layer, is combined with a plain weave fabric layer to form a double-layer structure.

[0010] The base material, cotton fabric, serves as a single-sided base material to support and secure the subsequent yarn structure, providing a stable mechanical foundation.

[0011] Preferably, the flexible integrated circuit uses silver nanowires as conductors and fabric as a carrier, and arranges the silver nanowires in the clothing using a combination of multi-unit series and parallel configurations.

[0012] Preferably, the silver thread is mainly arranged along the side seam of the garment and connected to each functional module through conductive fabric, and the modules are connected in series to achieve circuit connection.

[0013] Preferably, the pressure sensor module consists of multiple pressure sensors, which are arranged in parallel on the flexible integrated circuit.

[0014] Preferably, the vibration feedback device is integrated inside the main body of the garment.

[0015] Preferably, the flexible energy storage device is connected to the main body of the garment by splicing fabric together.

[0016] This utility model discloses a self-generating posture correction integrated smart garment based on a triboelectric nanogenerator, which has the following beneficial effects:

[0017] 1. Utilizing triboelectric nanogenerator technology, a self-generating intelligent garment integrating posture correction was designed and developed.

[0018] 2. A flexible, self-generating nano-triboelectric generator with excellent triboelectric properties was fabricated by using PI-coated polyester and nylon yarns to form an interwoven fabric structure, selecting PPy polymer as the electrode material, and using cotton fabric as the substrate.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] This application provides a self-generating intelligent garment for posture correction based on a triboelectric nanogenerator. This solves the problems of existing posture correction products for teenagers, which have limited functionality, lack real-time monitoring and feedback modules, and cannot effectively help teenagers adjust their posture in a timely manner. At the same time, existing products suffer from problems such as low applicability, inconvenience in wearing, poor comfort, and low accuracy due to unreasonable structural design and material selection, which to some extent reduces teenagers' willingness to use them. Battery-powered intelligent garments on the market have problems such as limited battery life, the need for regular replacement and maintenance, and environmental pollution after use.

[0026] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0027] This utility model discloses a self-generating posture correction integrated smart garment based on a triboelectric nanogenerator, according to the attached... Figure 1-3 As shown, the garment includes a main body 10, on which a TENG nanogenerator 2 is mounted. The main body 10 also has a flexible integrated circuit 4 connected to the TENG nanogenerator 2. The flexible integrated circuit 4 is connected to a flexible energy storage device 3, a pressure sensor module 5, and a vibration feedback device 1. The TENG nanogenerator 2 includes:

[0028] PI-coated polyester yarn 221 is a polyester yarn formed by coating with PI solution.

[0029] Nylon yarn 222, together with PI coated polyester yarn 221, is woven into a plain weave fabric layer 22;

[0030] The conductive polymer PPy layer 23 and the plain weave fabric layer 22 form the carrier 23 of the conductive polymer PPy layer. PPy is used as an electrode material and is uniformly coated on the PI-coated polyester yarn 221 and nylon yarn 222.

[0031] Nylon fabric 24, as the second layer of fabric, is combined with plain weave fabric layer 22 to form a double-layer structure.

[0032] The base material 21, a cotton fabric, serves as a single-sided base material 21 to support and fix the subsequent yarn structure, providing a stable mechanical foundation.

[0033] During the fabrication of TENG nanogenerator 2:

[0034] 1. Preparation of the first layer of nanogenerator fabric: First, polyester yarn with toughness, durability, and a diameter slightly larger than nylon yarn was selected. A PI solution was uniformly coated onto the surface of the polyester yarn using an impregnation method. During the coating process, the thickness and uniformity of the coating were controlled to ensure its quality and performance. The PI-coated polyester yarn was then dried to remove solvent and moisture. Next, it was cured at high temperature to ensure a tight bond between the PI coating and the polyester yarn, forming a stable PI-coated polyester yarn 221. Second, a conductive polymer PPy with good flexibility, conductivity, and cost-effectiveness was selected as the electrode material. The conductive polymer PPy was uniformly coated onto the PI-coated polyester yarn 221 and the nylon yarn 222, ensuring a tight bond between the PPy layer and the yarn, exhibiting uniform conductivity. The PPy-PI-polyester and PPy-nylon yarn layers formed a conductive layer. Finally, a plain weave fabric is formed by weaving nylon yarn 222 with PPy electrodes and PI-coated polyester yarn 221 to create a plain weave fabric layer 22. Cotton fabric is used as a single-sided substrate material 21 to support and fix the PI-coated polyester yarn 221. The PI-coated polyester yarn 221 is interwoven or embedded into the cotton fabric to form a stable single-electrode nanogenerator fabric.

[0035] 2. Composite of the second layer of fabric: The nylon fabric 24 is composited with the first plain weave fabric layer 22. By utilizing the difference in the diameter of the warp and weft yarns of the first layer of fabric, the structure of the double-layer composite fabric is designed. Through the composite of the nylon fabric 24 and the PI-coated polyester fabric with a larger diameter, the fabrics can achieve relative contact and separation, converting human mechanical energy into electrical energy.

[0036] This smart garment features a carefully designed layout for key functional modules. In the design of this integrated posture correction smart garment, the TENG nanogenerator 2 and the pressure sensor module 5 are crucial functional modules, and their placement is extremely important. The TENG nanogenerator 2 converts the mechanical energy of human movement into electrical energy through friction between fabric fibers and yarns. Therefore, the TENG nanogenerator 2 should be placed in areas of the garment body 10 prone to friction. According to ergonomics, areas where friction occurs most frequently during human movement include the armpits, cuffs, and collar. The comfort and aesthetics of the garment body 10 must also be considered. This invention uses a T-shirt as a carrier, placing the friction nanogenerator in the main friction area—the armpit—effectively utilizing friction to generate electricity while ensuring both aesthetics and comfort. Furthermore, the accuracy of intelligent monitoring greatly affects the correction effect. Based on research on areas where adolescents frequently experience posture problems, the pressure sensor module 5 is installed in the main areas where the user's body contacts the garment body 10 when sitting. Multiple pressure sensors in the pressure sensor module 5 are placed on both sides of the waist, the cervical spine, and the spine, directly reflecting the user's posture and providing accurate pressure data.

[0037] The overall circuit layout of the intelligent clothing system:

[0038] Using silver nanowires as conductors and fabric as a carrier, a multi-unit series-parallel configuration is employed to arrange the silver nanowires within the garment body 10, connecting various functional modules to achieve efficient collaborative operation of the entire system. To achieve centralized wiring and ensure the comfort and aesthetics of the garment body 10, the silver wires are primarily arranged along the side seams of the garment body 10, connecting to each functional module via conductive fabric. The modules are connected in series, organically integrating with each other for efficient system operation. The self-generating posture correction integrated smart garment contains multiple pressure sensors, with key detection points relatively dispersed. Parallel circuitry connects these functional modules, ensuring each pressure sensor operates independently; a failure in one component will not affect the normal operation of others, further guaranteeing overall system stability. When the pressure sensor module 5 detects incorrect posture, the vibration feedback device 1 alerts the user to correct their posture through vibration. To ensure the effective operation of the vibration feedback device 1 and the garment's aesthetic appeal, the vibration feedback device 1 is integrated into the inside of the garment. Flexible energy storage materials are selected as external energy storage modules, which are spliced ​​together with fabric and have sufficient capacity to meet the long-term use requirements of smart clothing.

[0039] In summary, this self-generating posture correction integrated smart garment based on triboelectric nanogenerators: 1. By utilizing triboelectric nanogenerator technology, this self-generating posture correction integrated smart garment overcomes the limitations of traditional smart garments that rely on battery power, converting the mechanical energy generated by human activity into electrical energy to power the posture monitoring and correction system. This not only improves the comfort and lightweight nature of the garment but also ensures the continuous and stable operation of the posture monitoring and correction system, improving the accuracy of monitoring.

[0040] 2. A flexible, self-generating nano-triboelectric generator with excellent triboelectric properties was fabricated by using PI-coated polyester yarn and nylon yarn 222 to form an interwoven structure fabric, selecting PPy polymer as the electrode material, and cotton fabric as the substrate. This allows the generator to maintain good flexibility while having high energy conversion efficiency, providing sufficient energy for the posture correction system.
