Description

Fabric and terminals

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on November 17, 2023, with application number 202311550958.3 and application name “Fabric and Terminal”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of electronic technology, and in particular to a fabric and a terminal. Background Art

[0003] With the development of textile technology and the improvement of people's living standards, fabrics are gradually developing in the direction of functionalization and intelligence. Due to the characteristics of fabrics such as softness and structural stability, compared with traditional printing and coating processes, fabrics have more stable perception capabilities. Therefore, they can be widely used in various terminals to perceive information in different modes. For example, the surface of a vehicle's steering wheel can be a fabric that can perceive the user's physiological information. For another example, the surface of a seat (for example, the backrest surface and armrest surface of a seat) can be a fabric that can perceive touch information and pressure information.

[0004] However, these fabrics can only sense one type of information on a single piece of fabric. In other applications, the same fabric needs to sense information from multiple modalities simultaneously. For example, a seat armrest surface requires three sensing areas to sense physiological information, touch information, and pressure information.

[0005] To achieve this multi-sensory function, some technical solutions involve stitching together different fabrics used for different sensory functions. However, due to differences in the molding processes and materials used for these fabrics, as well as the presence of sewing structures between the fabrics to secure them, the resulting fabrics have limited tactile feel and aesthetic appeal.

[0006] To this end, in other technical solutions, conductive fibers can be woven into different areas of the same fabric or printed with conductive coatings to achieve different sensing functions. However, the sensing parts of different sensing functions also require different mechanical properties of the fabric (for example, elasticity or compressibility). Currently, it is difficult for the same fabric to meet the different mechanical property requirements of different sensing functions, and the sensing effect needs to be improved.

[0007] Summary of the Invention

[0008] Some embodiments of the present application provide a fabric and a terminal. The present application is introduced from multiple aspects below, and the embodiments and beneficial effects of the following aspects can be referenced to each other.

[0009] In a first aspect, embodiments of the present application provide a fabric. The fabric includes a first braid and a second braid located in different regions, wherein the first braid and the second braid are respectively configured to implement different sensory functions, the first braid and the second braid are connected by a braided structure, and the braiding material of the second braid is different from the braiding material of the first braid, such that at least one mechanical property of the second braid is different from that of the first braid.

[0010] According to an embodiment of the present application, the braiding material of the second braid is different from the braiding material of the first braid, so that at least one mechanical property of the second braid can be different from that of the first braid. In this way, the different mechanical properties required for different sensory functions can be better taken into account, thereby improving the sensory effect of the fabric. In addition, the fabric provided by this application can be produced in an integrated manner based on existing industrial equipment (e.g., knitting machines) without the need for multi-step molding processes, resulting in low molding difficulty and production costs and high production efficiency.

[0011] In some embodiments, the braiding material of the second braid includes functional fibers different from those of the first braid, so that the elasticity of the second braid is less than that of the first braid, thereby effectively improving the stability of the second braid in sensing information.

[0012] In some embodiments, the second braid is used to sense touch information. The second braid includes a stacked conductive layer and an insulating layer. The conductive layer is woven from conductive fibers and functional fibers, and / or the insulating layer is woven from insulating fibers and functional fibers. This effectively improves the stability of the second braid in sensing touch information.

[0013] In some embodiments, the conductive layer is woven together by conductive fibers and functional fibers. The conductive fibers and functional fibers can be woven in one of the following ways: the functional fibers and the conductive fibers are intertwined or arranged in parallel to form a fiber group for weaving, or the functional fibers and the conductive fibers are alternately arranged and woven.

[0014] In some embodiments, the conductive layer includes multiple conductive areas, and the multiple conductive areas are arranged in a one-dimensional array or a two-dimensional array, so as to sense different touch information.

[0015] In some embodiments, the multiple conductive regions are arranged in a two-dimensional array, wherein the conductive layer includes two stacked sub-conductive layers, the stacking direction of the two sub-conductive layers being parallel to the stacking direction of the conductive layer and the insulating layer. The two sub-conductive layers each include multiple sub-conductive regions, and the multiple sub-conductive regions of the two sub-conductive layers are arranged in a one-dimensional array, and the arrangement directions of the multiple sub-conductive regions of the two sub-conductive layers are perpendicular to each other. In this way, the second braid can sense sliding touch in a two-dimensional direction and the specific location of the touch, thereby expanding the scope of application.

[0016] In some embodiments, the second braid is used to sense touch information. The second braid includes a conductive layer woven from conductive fibers and functional fibers, with the functional fibers wrapped around the conductive fibers. This effectively improves the stability of the second braid in sensing touch information.

[0017] In some embodiments, the second braid is used to sense pressure information. The second braid includes two stacked conductive layers, the two conductive layers are insulated and connected, and at least one of the two conductive layers is woven from conductive fibers and functional fibers. This can effectively improve the stability of the second braid in sensing pressure information.

[0018] In some embodiments, the functional fibers include thermoplastic fibers.

[0019] According to an embodiment of the present application, the thermoplastic fibers can melt when heated and partially adhere to or cover the other woven materials of the second woven body. After the thermoplastic fibers cool, they can limit the elasticity of the second woven body, thereby improving the stability of the sensed information.

[0020] In some embodiments, the thermoplastic fiber is any one of polyamide fiber, polyester fiber, or polypropylene fiber.

[0021] In some embodiments, the braiding material of the second braid includes functional fibers different from those of the second braid, so that the compressibility of the second braid is less than that of the first braid, thereby increasing the range of information sensing by the second braid.

[0022] In some embodiments, the second braid is used to sense pressure information. The second braid includes two stacked conductive layers and an insulating layer interposed between the two conductive layers. The insulating layer is woven from insulating fibers and functional fibers. This can increase the range of pressure information sensed by the second braid.

[0023] In some embodiments, the functional fibers include elastic fibers.

[0024] According to the embodiment of the present application, the elastic fiber can provide elastic support for the second braid, making the second braid less compressible, that is, reducing the compressibility of the second braid, so that the second braid can sense a wider range of pressure.

[0025] In some embodiments, the elastic fiber is made of any one of polyurethane, polyacrylate or polyester.

[0026] In some embodiments, the two conductive layers each include multiple conductive regions, and the multiple conductive regions of the two conductive layers are arranged in a one-dimensional array. Furthermore, along the stacking direction of the two conductive layers, the projections of the multiple conductive regions of the two conductive layers on the insulating layer overlap. This allows the second braid to sense pressure at multiple different locations in a one-dimensional direction.

[0027] In some embodiments, the two conductive layers each include multiple conductive regions, and the multiple conductive regions of the two conductive layers are arranged in a one-dimensional array, with the arrangement directions of the multiple conductive regions of the two conductive layers being perpendicular to each other, or the multiple conductive regions of the two conductive layers are arranged in a two-dimensional array, and along the stacking direction of the two conductive layers, the projections of the multiple conductive regions of the two conductive layers on the insulating layer overlap. This allows the second braid to sense pressure at multiple different locations in the two-dimensional direction.

[0028] In some embodiments, the first braided body is used to sense physiological information, and the first braided body includes a conductive layer woven from conductive fibers.

[0029] In some embodiments, the first braid is used to sense touch information or physiological information.

[0030] In some embodiments, the braided structure is woven from insulating fibers.

[0031] In some embodiments, the conductive fiber is carbon fiber, copper wire, silver wire, stainless steel wire, or natural fiber or synthetic fiber coated with a conductive material.

[0032] In some embodiments, the conductive material is gold, silver, silver nanowires, or copper.

[0033] In some embodiments, the insulating fiber is cotton fiber, wool fiber, linen fiber, silk fiber, polyester fiber, spandex fiber, acrylic fiber, aramid fiber, nylon fiber, acrylic fiber, polypropylene fiber, polyester fiber, or nylon fiber.

[0034] In a second aspect, an embodiment of the present application provides a terminal, which includes a main body and any one of the fabrics in the first aspect and possible implementations of the first aspect. BRIEF DESCRIPTION OF THE DRAWINGS

[0064] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0065] First, some concepts or terms involved in this application are explained so that those skilled in the art can understand them.

[0066] (1) Perceiving physiological information

[0067] Figure 1A shows a schematic diagram of sensing physiological information in an embodiment of the present application. Referring to Figure 1A, when the user's skin is in direct contact with the conductive layer 101, the conductive layer 101 can act as a sensor to obtain physiological information from the skin surface, such as electrocardiogram (ECG) signals, electromyography (EMG) signals, or electrodermal signals.

[0068] (2) Perceiving touch information

[0069] FIG1B shows a schematic diagram of sensing touch information in an embodiment of the present application. Referring to FIG1B , touch information can be sensed based on changes in the amplitude of a capacitance signal. Specifically, a conductive layer 201 and an insulating layer 202 are stacked. The conductive layer 201 can form an electric field and generate a capacitance signal. The insulating layer 202 is configured to contact the user's finger to prevent the user's finger from directly contacting the conductive layer 201, thereby preventing the user's finger from affecting the generation of the capacitance signal. When the user's finger approaches the conductive layer 201, the amplitude of the capacitance signal increases; conversely, when the user's finger moves away from the conductive layer 201, the amplitude of the capacitance signal decreases. Therefore, touch information can be sensed based on changes in the amplitude of the capacitance signal. The touch information can include single click, double click, long press, swipe up, swipe down, swipe left, swipe right, pinch, multi-finger swipe, and full-hand interaction (for example, touching the fabric with the user's entire hand, covering the fabric with the user's entire hand, pressing the fabric with the user's entire hand, palm touch, and flipping, twisting, or rotating the user's hand while contacting the fabric).

[0070] (3) Perceiving pressure information

[0071] FIG1C shows a schematic diagram of sensing pressure information in an embodiment of the present application. Referring to FIG1C , pressure information can be sensed based on the amplitude change of the capacitance signal. Specifically, the first conductive layer 301a and the second conductive layer 301b are stacked, and an insulating layer 302 is further provided between the first conductive layer 301a and the second conductive layer 301b. The first conductive layer 301a, the second conductive layer 301b and the insulating layer 302 together form a flat plate capacitor. The capacitance value of the flat plate capacitor depends on the area of ​​the first conductive layer 301a and the second conductive layer 301b, and the distance D1 between the first conductive layer 301a and the second conductive layer 301b. When the user presses on the first conductive layer 301a, the distance D1 between the first conductive layer 301a and the second conductive layer 301b decreases, thereby increasing the amplitude of the capacitance. The degree of increase in the capacitance amplitude is related to the amount of pressure applied by the user to the first conductive layer 301a. Therefore, pressure information can be sensed based on the amplitude change of the capacitance, for example, the amount of pressure or pressure at different positions can be identified.

[0072] The embodiments of the present application provide a fabric and a terminal including the fabric. The fabric provided in the embodiments of the present application is integrally formed and can realize a variety of different sensing functions (for example, the touch information, pressure information, or physiological information described above). Different parts of the fabric have different mechanical properties for different sensing functions, thereby effectively improving the sensing effect.

[0073] It is understood that the terminals provided in this application include, but are not limited to, vehicles, wearable devices (e.g., augmented reality (AR) glasses, virtual reality (VR) glasses, mixed reality (MR) glasses, smart helmets, smart watches, smart bracelets), smart home terminals (e.g., smart sofas, smart massage chairs), and any other terminals with fabric surfaces, and this application does not specifically limit this. For ease of description, the following uses a vehicle as an example to introduce the technical solution of this application.

[0074] Figure 2 shows an exemplary structural diagram of a vehicle 1 according to an embodiment of the present application. Referring to Figure 2 , vehicle 1 includes a fabric 10, a vehicle body 11, seats 12, and a steering wheel 13. Vehicle body 11 defines a vehicle compartment 14 within which seats 12 and steering wheel 13 are disposed.

[0075] The seat 12 includes an armrest 15, a seat cushion 16, a backrest 17, and a headrest 18. For example, the fabric 10 can be covered on the armrest 15 (as an example of a main body) of the seat 12 to serve as the outer surface of the armrest 15. It should be noted that in the embodiments of the present application, the outer surface of each component refers to the surface of each component facing the user during actual use, that is, the surface of each component that is in direct contact with the user; the surface opposite to the outer surface is the inner surface, that is, the surface of each component facing away from the user during actual use, which will not be described in detail below.

[0076] The fabric 10 can be used to sense information of one or more modalities to facilitate intelligent interaction within the vehicle.

[0077] In some embodiments of the present application, fabric 10 can be used to sense physiological information. For example, when a user's hands come into contact with fabric 10 on armrests 15 on either side of seat 12, the user's heart rate, electrocardiogram (ECG) and other information can be acquired. This information can then be used to determine the user's health status, fatigue level, and stress level, facilitating health monitoring.

[0078] In some embodiments of the present application, the fabric 10 can also be used to sense touch information. When a user performs a specific touch gesture on the fabric 10 (e.g., single-click, double-click, long press, swipe up, swipe down, swipe left, swipe right, pinch, multi-finger swipe, and full-hand interaction (e.g., touching the fabric with the user's entire hand, covering the fabric with the user's entire hand, pressing the fabric with the user's entire hand, palm touch, and flipping, twisting, or rotating the user's hand while in contact with the fabric), etc.), the vehicle 1 can perform the operation corresponding to the gesture, such as playing music, switching music, pausing, playing, or switching content played on the in-car screen, etc.

[0079] In some embodiments of the present application, fabric 10 can also be used to sense pressure information. For example, when a user presses different locations on fabric 10 with varying pressures, vehicle 1 can perform corresponding operations based on the pressed locations and pressure levels, such as adjusting the fore-aft position of seat 12, the angle of seat back 17, and the height of seat headrest 18 to improve seat comfort.

[0080] It will be appreciated that the above embodiment merely illustrates that the fabric 10 is the outer surface of the armrest 15 of the seat 12. In other embodiments, the fabric 10 may also be used in other components of the vehicle 1. For example, the fabric 10 may also serve as the outer surface of the steering wheel 13, seat cushion 16, backrest 17, headrest 18, door handles (not shown), or roof of the vehicle 1, without any limitation in this application.

[0081] It will also be understood that FIG2 schematically illustrates only some structural components contained within the vehicle 1, and the actual structure and position of these structural components are not limited by FIG2 . Furthermore, the vehicle 1 may include more or fewer structural components relative to the structural components shown in FIG2 . For example, the vehicle 1 may also include a circuit module and a processor that are communicatively connected to the fabric 10 . The circuit module is used to acquire signals emitted by the fabric 10 (e.g., capacitive signals or physiological signals from the user's skin), and the processor is used to analyze and identify corresponding information (e.g., touch information, pressure information, or physiological information) based on the signals acquired by the circuit module, thereby enabling convenient interaction within the vehicle.

[0082] As mentioned above, different sensing functions need to be realized through different structures. In order to realize the above-mentioned multiple different sensing functions on the same fabric at the same time, in some technical solutions, the fabrics used to realize different sensing functions can be spliced ​​into one to form a fabric.

[0083] Figure 3 shows a schematic diagram of the structure of a fabric 10' in some technical solutions. Referring to Figure 3, fabric 10' is composed of a first sensing portion 100', a second sensing portion 200', and a third sensing portion 300', which are sewn together. The first sensing portion 100' is used to sense physiological information. The second sensing portion 200' is used to sense touch information. The third sensing portion 300' is used to sense pressure information.

[0084] Since the first sensing part 100', the second sensing part 200' and the third sensing part 300' are spliced ​​together by sewing, there is a sewing structure 400' between the first sensing part 100', the second sensing part 200' and the third sensing part 300'. The sewing structure 400' will affect the touch feel and the beauty and refinement of the appearance. In addition, in order to achieve different sensing functions, there are also differences in fabric materials and molding processes between the first sensing part 100', the second sensing part 200' and the third sensing part 300', which will also affect the touch feel and the beauty and refinement of the appearance.

[0085] To this end, in other technical solutions, conductive fibers can be woven into different areas of the same fabric or conductive coatings can be printed to achieve different sensing functions.

[0086] For example, FIG4 shows a schematic structural diagram of a fabric 10″ in other technical solutions. Referring to FIG4 , the fabric 10″ includes a fabric body 101″ and a conductive layer 102″. The conductive layer 102″ is attached to different areas of the fabric body 101″ by printing to form sensing parts with different sensing functions.

[0087] Specifically, the conductive layer 102″ is attached to the outer surface 1012″ of the fabric body 101″ so as to form a first sensing portion 100″ together with the fabric body 101″. The first sensing portion 100″ is used to sense physiological information. The conductive layer 102″ is attached to the inner surface 1011″ of the fabric body 101″ so as to form a second sensing portion 200″ together with the fabric body 101″. The second sensing portion 200″ is used to sense touch information. The conductive layer 102″ is attached to the inner surface 1011″ and the outer surface 1012″ of the fabric body 101″, which are arranged opposite to each other, so as to form a third sensing portion 300″ together with the fabric body 101″. The third sensing portion 300″ is used to sense touch information.

[0088] However, different sensing parts have different mechanical property requirements for the fabric. The aforementioned fabric 10" simply adds a conductive coating 102" to different areas of the fabric body 101" to form the first sensing part 100", the second sensing part 200", and the third sensing part 300". Therefore, due to the limitations of the fabric body 101", it is difficult for the fabric 10" to simultaneously meet the different mechanical property requirements of the sensing parts with different sensing functions, and the sensing effect needs to be improved.

[0089] For example, the second sensing part 200 ″ used to sense touch information needs to have relatively small elasticity. If the user touches the second sensing part 200 ″, the woven structure of the second sensing part 200 ″ undergoes relatively obvious deformation and displacement, which will cause the amplitude of the capacitance signal to change, thereby affecting the stability of the touch information sensed by the second sensing part 200 ″.

[0090] The third sensing portion 300″ for sensing pressure information needs to have appropriate compressibility. For example, sensing a larger range of pressure requires smaller compressibility, while sensing a smaller range of pressure requires larger compressibility. In addition, the third sensing portion 300″ also needs to have smaller elasticity. If a user touches the third sensing portion 300″, the woven structure of the conductive layer 102″ constituting the third sensing portion 300″ undergoes significant deformation and displacement, which will cause the amplitude of the capacitance signal to change, thereby affecting the stability of the pressure information sensed by the third sensing portion 300″.

[0091] In order to solve the above problems, the present application provides a fabric, which includes at least two sensing parts for realizing different sensing functions. By weaving a woven material different from that of the other sensing part into one of the sensing parts, the mechanical properties (for example, elasticity or compressibility) of the sensing part can be changed, so that the different requirements of different sensing functions for the mechanical properties of the fabric can be met in an one-piece molded fabric, effectively improving the sensing effect. The technical solution of the present application is described in detail below with reference to the accompanying drawings.

[0092] Figures 5A to 5C show schematic structural diagrams of a fabric 10 in an embodiment of the present application, wherein Figure 5A is a top view of the fabric 10, Figure 5B is a side view of the fabric 10, and Figure 5C is a partially enlarged view of the fabric 10 in the S0 region in Figure 5A. For ease of observation and distinction, each type of filling area in Figures 5B and 5C represents a type of fiber. Furthermore, a blank gap is left between two adjacent layers of fabric structure of the fabric 10 in Figure 5B, but it is understood that in actual application, the fabric 10 has soft properties, so its two adjacent layers of fabric structure will contact each other. Furthermore, Figure 5B only schematically illustrates the types of fibers included in each layer of the fabric 10, and does not limit the relative positional relationship and connection method between the various types of fibers in each layer. For example, the various types of fibers in the top layer can be interwoven and woven as shown in Figure 5C.

[0093] 5A to 5C , fabric 10 includes a first braid (e.g., the first sensing portion 100 described below) and a second braid (e.g., the second sensing portion 200 or the third sensing portion 300 described below). The first braid and the second braid are located at different positions and are connected by a braided structure 20. In other words, the first braid, the second braid, and the braided structure 20 can be integrally formed. Therefore, fabric 10 can be integrally formed using existing industrial equipment (e.g., a knitting machine).

[0094] The first braid and the second braid are respectively used to realize different sensing functions. The braiding material of the second braid is different from the braiding material of the first braid, so that at least one mechanical property of the second braid is different from that of the first braid. In this way, the different mechanical properties required for different sensing functions can be better taken into account, thereby improving the sensing effect of the fabric 10. In addition, compared with the solution of splicing multiple different fabrics by sewing, and weaving conductive fibers or printing conductive coatings on a piece of fabric, the fabric 10 provided in the present application can be produced in an integrated manner based on existing industrial equipment (for example, a knitting machine) without the need for multi-step molding, with low molding difficulty and production cost and high production efficiency.

[0095] Several forms of the first braided body and the second braided body are described below with reference to the accompanying drawings.

[0096] Continuing with Figures 5A to 5C , in some embodiments of the present application, the fabric 10 includes a first sensing portion 100 and a second sensing portion 200 for implementing different sensing functions. The first sensing portion 100 may be an example of a first woven fabric, and the second sensing portion 200 may be an example of a second woven fabric.

[0097] The first sensing part 100 is used to sense physiological information, while the second sensing part 200 is used to sense touch information. The woven material of the second sensing part 200 includes a different functional fiber (e.g., thermoplastic fiber 410) than the first sensing part 100, resulting in a lower elasticity of the second sensing part 200 than the first sensing part 100, ensuring stable touch information sensing.

[0098] Specifically, the functional fibers include thermoplastic fibers 410. Thermoplastic fibers 410 soften and melt when heated, and solidify into a solid when cooled. Therefore, when exposed to heat, the thermoplastic fibers 410 can melt and partially adhere to or coat the other woven materials of the second sensing portion 200. After the thermoplastic fibers 410 cool, they can limit the relative movement between the woven structures of the second sensing portion 200, thereby making the woven structure of the second sensing portion 200 more compact. This can effectively reduce the elasticity of the second sensing portion 200, ensuring that when a user's finger touches the second sensing portion 200, the second sensing portion 200 is less likely to deform or shift significantly. Different pressing forces have little effect on the deformation of the second sensing portion 200, effectively improving the stability of the second sensing portion 200 in sensing touch information.

[0099] In some embodiments of the present application, the fabric 10 further includes a third sensing portion 300 for realizing different sensing functions. The third sensing portion 300 may be another example of the second braid.

[0100] The third sensing part 300 is used to sense pressure information. The woven material of the third sensing part 300 includes a different functional fiber (e.g., thermoplastic fiber 410) than the second sensing part 200, making the elasticity of the third sensing part 300 less than that of the first sensing part 100, thereby ensuring the stability of the pressure information sensed.

[0101] Specifically, the functional fibers include thermoplastic fibers 410. When heated, the thermoplastic fibers 410 melt and partially adhere to or coat the other woven materials of the third sensing portion 300. After cooling, the thermoplastic fibers 410 restrict relative movement within the woven structure of the third sensing portion 300, thereby tightening the woven structure. This effectively reduces the elasticity of the third sensing portion 300, ensuring that the third sensing portion 300 is less likely to deform or shift significantly when pressed by a user's finger. This effectively improves the stability of the third sensing portion 300's perception of pressure information.

[0102] For example, Figure 6A illustrates a schematic diagram of the sensing effect when the third sensing portion 300 does not include thermoplastic fibers 410 in an embodiment of the present application. Figure 6B illustrates a schematic diagram of the sensing effect when the third sensing portion 300 includes thermoplastic fibers 410 in an embodiment of the present application. As shown in Figure 6A , when the third sensing portion 300 does not include thermoplastic fibers 410, the capacitance change resulting from multiple presses at different forces varies significantly. For example, the capacitance change after 100 presses at 20 kPa is approximately 0.3, while the capacitance change after 500 presses at 20 kPa is approximately 0.2. This can lead to inaccurate pressure information. As shown in Figure 6B , after the third sensing portion 300 is provided with thermoplastic fibers 410, the capacitance change resulting from multiple presses at different forces is approximately the same. Therefore, the third sensing portion 300 achieves greater stability in sensing pressure information and is less affected by pre-stretching and cyclic stretching.

[0103] In some embodiments of the present application, the functional fibers (e.g., elastic fibers 420) of the third sensing portion 300 may also make the compressibility of the third sensing portion 300 less than that of the second sensing portion 200, so as to be able to sense a larger pressure range.

[0104] Specifically, the functional fibers include elastic fibers 420. The elastic fibers 420 have a certain elasticity and can be compressed when subjected to pressure and rebound to their original state after the pressure is released. This provides elastic support for the third sensing portion 300, making the third sensing portion 300 less compressible. In other words, the compressibility of the third sensing portion 300 is reduced, thereby enabling the third sensing portion 300 to sense a wider range of pressure.

[0105] It is understood that the ability of the third sensing portion 300 to sense pressure depends on the compressibility of the third sensing portion 300. A greater compressibility of the third sensing portion 300 allows for more sensitive sensing of slight pressure changes, while a less compressible third sensing portion 300 allows for sensing a wider range of pressure values.

[0106] In some embodiments of the present application, elastic fibers 420 of varying thicknesses can be selected based on actual application scenarios, thereby ensuring that the third sensing portion 300 has appropriate compressibility. The thickness of the elastic fibers 420 can be characterized by the diameter of a single elastic fiber 420 . A larger diameter indicates a thicker elastic fiber 420 , while a smaller diameter indicates a thinner elastic fiber 420 .

[0107] FIG7 shows a schematic diagram of the relationship between the size of the pressure sensing range of the third sensing part 300 and the thickness of the elastic fiber 420 in an embodiment of the present application. Referring to FIG7 , when the third sensing part 300 does not include the elastic fiber 420, the capacitance change of the third sensing part 300 under different pressures is most obvious, and the sensitivity is higher. Therefore, when the user lightly touches the third sensing part 300, a large capacitance change will occur in the third sensing part 300, thereby sensing pressure information, which is prone to problems such as false touch, and is not suitable for application scenarios with frequent contact with the outside world. When the third sensing part 300 includes elastic fibers 420, as the elastic fibers 420 change from thin to thick, the capacitance change of the third sensing part 300 under different pressures gradually decreases, and the sensitivity is moderate, so that a larger range of pressure can be sensed, and the scope of application is wider.

[0108] It can be understood that the forms of the above-mentioned first braid and second braid are merely exemplary illustrations of the technical solutions of the present application, and those skilled in the art may make other modifications. For example, in the present embodiment, the first sensing portion 100 is an example of the first braid, and the second sensing portion 200 and the third sensing portion 300 are an example of the second braid. In other embodiments, the fabric 10 may include a second sensing portion 200 and a third sensing portion 300. The second sensing portion 200 can serve as an example of the first braid. The third sensing portion 300 is an example of the second braid. The woven material of the third sensing portion 300 includes functional fibers (e.g., elastic fibers 420) that are different from those of the second sensing portion 200, so that the compressibility of the third sensing portion 300 is less than the compressibility of the second sensing portion 200, so as to ensure the stability of the perceived pressure information.

[0109] The following describes the exemplary structures of the various sensing parts in the fabric 10 and the arrangement of the functional fibers therein in conjunction with the accompanying drawings.

[0110] 5B and 5C , in some embodiments of the present application, the first sensing portion 100 includes a conductive layer 101 . The conductive layer 101 is woven from conductive fibers 500 .

[0111] FIG8 shows another exemplary structure of the first sensing part 100 of the present application. As shown in FIG8 , the first sensing part 100 may further include a conductive layer 101 and an insulating layer 102 stacked along the Z direction. The surface of the conductive layer 101 forms part of the outer surface of the fabric 10, and the surface of the insulating layer 102 forms part of the inner surface of the fabric 10. In other words, the conductive layer 101 is used to directly contact the user's skin, thereby realizing the function of sensing physiological information. In some implementations, the insulating layer 102 can be woven from insulating fibers 600.

[0112] It can be understood that the present application does not limit the specific structure of the first sensing part 100, as long as it ensures that the conductive layer 101 is in direct contact with the user's skin to achieve the function of sensing physiological information.

[0113] Continuing with Figure 5B , the second sensing portion 200 includes a conductive layer 201 and an insulating layer 202 stacked along the Z direction. Along the Z direction, the surface of the conductive layer 201 forms part of the inner surface of the fabric 10. The surface of the insulating layer 202 forms part of the outer surface of the fabric 10. In other words, the insulating layer 202 is designed to come into direct contact with the user's skin, preventing the user's finger from affecting the generation of the capacitive signal and ensuring that the second sensing portion 200 can properly sense touch information.

[0114] As previously mentioned, in some embodiments of the present application, the second sensing portion 200 may include thermoplastic fibers 410. Thermoplastic fibers 410 can reduce the elasticity of the second sensing portion 200, thereby improving the stability of the second sensing portion 200 in sensing touch information. Several exemplary arrangements of thermoplastic fibers 410 within the second sensing portion 200 are described below with reference to the accompanying figures.

[0115] In some embodiments of the present application, the conductive layer 201 is woven together by thermoplastic fibers 410 and conductive fibers 500 . The thermoplastic fibers 410 can limit the relative movement between adjacent conductive fibers 500 after heating and cooling, thereby effectively reducing the elasticity of the conductive layer 201 .

[0116] It can be understood that the thermoplastic fibers 410 and the conductive fibers 500 in this application can be woven in various ways.

[0117] FIG9 shows a schematic diagram of weaving thermoplastic fibers 410 and conductive fibers 500 in an embodiment of the present application. Referring to FIG9 , the thermoplastic fibers 410 and the conductive fibers 500 can form a fiber group 700 together, and the fiber group 700 is woven to form a conductive layer 201 .

[0118] In some implementations, the thermoplastic fibers 410 and the conductive fibers 500 are arranged side by side to form the fiber group 700. That is, the thermoplastic fibers 410 and the conductive fibers 500 are aligned with each other, and the extension trajectory of the thermoplastic fibers 410 is substantially the same as that of the conductive fibers 500.

[0119] In some other implementations, the thermoplastic fibers 410 can be intertwined with the conductive fibers 500 to form a single body, thereby forming a fiber group 700. For example, Figures 10A and 10B illustrate schematic diagrams of several embodiments of the present application in which the thermoplastic fibers 410 and the conductive fibers 500 are intertwined. As shown in Figure 10A, the conductive fibers 500 can be used as the core yarn, and the thermoplastic fibers 410 can be spirally wound around the outer circumference of the conductive fibers 500 to form the fiber group 700. As shown in Figure 10B, the thermoplastic fibers 410 and the conductive fibers 500 can also be spirally wound together to form a fiber group 700 having a structure similar to a twisted braid.

[0120] It can be understood that the above FIG. 10A and FIG. 10B only illustrate a solution of partially winding the thermoplastic fiber 410 and the conductive fiber 500 , and do not constitute a specific limitation on the implementation of the present application.

[0121] Figure 11 shows another schematic diagram of the weaving of thermoplastic fibers 410 and conductive fibers 500 in an embodiment of the present application. Referring to Figure 11 , in some other embodiments of the present application, thermoplastic fibers 410 and conductive fibers 500 may be woven in an alternating pattern to form a conductive layer 201. For example, as shown in Figure 11 , the conductive layer 201 includes four rows of interwoven fibers. The first and third rows contain thermoplastic fibers 410, while the second and fourth rows contain conductive fibers 500.

[0122] It is understood that the area where the conductive fibers 500 of the conductive layer 201 are located forms a conductive area, allowing the second sensing portion 200 to sense touch information. Different distribution patterns of the conductive fibers 500 form different numbers of conductive areas, and different numbers of conductive areas can achieve different touch sensing functions.

[0123] In some embodiments of the present application, the conductive layer 201 may include a conductive area. Figure 12 shows a schematic diagram of an embodiment of the present application in which the conductive layer 201 includes a conductive area 2011. Referring to Figure 12 and in combination with Figure 9, adjacent conductive fibers 500 are connected to each other and are not connected by insulating fibers (for example, thermoplastic fibers 410 or insulating fibers 600). That is, the conductive fibers 500 of the conductive layer 201 form a conductive area 2011. When the user's finger is placed at a position corresponding to the conductive area 2011 in the insulating layer (not shown), the capacitance signal amplitude of the conductive area 2011 will increase, thereby being able to identify touch information such as clicks (for example, single clicks, double clicks) and long presses.

[0124] In other embodiments of the present application, the conductive layer 201 may include multiple conductive areas to be able to sense more touch information, thereby further expanding the scope of application.

[0125] Specifically, FIG13A shows an exemplary arrangement of multiple conductive regions 2011 in the conductive layer 201 in an embodiment of the present application. Referring to FIG13A , the multiple conductive regions 2011 of the conductive layer 201 can be arranged in a one-dimensional array. That is, the multiple conductive regions 2011 are spaced apart along the same direction (e.g., the X direction shown in FIG13A ). The X direction is perpendicular to the Z direction (i.e., the direction perpendicular to the paper in FIG13A ).

[0126] In this way, the second sensing part 200 can also sense sliding touch in one dimension. Figure 13B shows an exemplary process of the second sensing part 200 sensing sliding touch in one dimension in an embodiment of the present application. Referring to Figure 13A and in combination with Figure 13B, when the user's finger is located at point P1, the capacitance signal amplitude of the conductive area 2011a is larger than the capacitance signal amplitude of other conductive areas. In the process of the user's finger sliding from point P1 to point P2, the capacitance signal amplitude of the conductive area 2011a gradually decreases, and the capacitance signal amplitude of the conductive area 2011b gradually increases. The second sensing part 200 can sense the sliding of the user's finger in the X direction based on the changes in the capacitance amplitudes of the conductive areas 2011a and 2011b.

[0127] FIG14 shows a second exemplary arrangement of multiple conductive regions 2011 in the conductive layer 201 in an embodiment of the present application. Referring to FIG14 , the multiple conductive regions 2011 of the conductive layer 201 can be arranged in a two-dimensional array. That is, the multiple conductive regions 2011 are spaced apart along the row direction (e.g., as shown in the Y direction in FIG14 ) and the column direction (e.g., as shown in the X direction in FIG14 ). Exemplarily, the X direction, the Y direction, and the Z direction (i.e., the direction perpendicular to the paper in FIG14 ) are perpendicular to each other.

[0128] In this way, the second sensing portion 200 can also sense sliding touches in two dimensions. Furthermore, based on this two-dimensional sliding touch sensing, the coordinates of the contact point between the user and the second sensing portion 200 in the X and Y directions can be obtained, enabling the second sensing portion 200 to sense the specific location of the user's finger touch. The specific principles of the second sensing portion 200 sensing sliding in two dimensions are essentially the same as the specific principles of the second sensing portion 200 sensing sliding in one dimension described above. For details, please refer to Figures 13A and 13B and the related descriptions, and will not be repeated here.

[0129] Several implementations of two-dimensional array arrangements of the plurality of conductive regions 2011 are described below with reference to the accompanying drawings.

[0130] Figure 15 shows a schematic diagram of the structure of a two-dimensional array of conductive regions 2011 in an embodiment of the present application. Referring to Figure 15 and in conjunction with Figure 14 , in some implementations, the conductive layer 201 of the second sensing portion 200 is a single-layer woven structure formed by thermoplastic fibers 410 and conductive fibers 500. Therefore, the conductive regions 2011 are single-layer structures, each of which is similar to a dot and arranged in a two-dimensional array, thereby forming a dot-matrix self-capacitive region.

[0131] 16A and 16B show schematic structural diagrams of another two-dimensionally distributed conductive region 2011 in an embodiment of the present application, wherein FIG16A is a top view of the conductive region 2011 and FIG16B is an exploded view of the conductive region 2011.

[0132] Referring to Figures 16A and 16B in conjunction with Figure 5B , in some alternative implementations, the conductive layer 201 of the second sensing portion 200 can be a double-layer woven structure formed of thermoplastic fibers 410 and conductive fibers 500. Thus, the conductive regions 2011 are double-layered, with each layer arranged in a one-dimensional array, and the two layers arranged perpendicularly to each other, ultimately forming a plurality of conductive regions 2011 arranged in a two-dimensional array.

[0133] Specifically, the conductive layer 201 of the second sensing portion 200 includes two sub-conductive layers: a first sub-conductive layer 201a and a second sub-conductive layer 201b. The first sub-conductive layer 201a and the second sub-conductive layer 201b are stacked along the Z direction. The first sub-conductive layer 201a includes a plurality of first sub-conductive regions 2011a. These first sub-conductive regions 2011a are each in the form of elongated strips and arranged in a one-dimensional array along the Y direction. The second sub-conductive layer 201b includes a plurality of second sub-conductive regions 2011b. These second sub-conductive regions 2011b are each in the form of elongated strips and arranged in a one-dimensional array along the X direction.

[0134] The first sub-conductive region 2011a and the second sub-conductive region 2011b have multiple overlapping portions in the Z direction, for example, multiple first portions S1 of the first sub-conductive region 2011a and multiple second portions S2 of the second sub-conductive region 2011b. Each first portion S1 and its overlapping second portion S2 in the Z direction can together form a conductive region 2011. Because the multiple first portions S1 and the multiple second portions S2 are distributed in a two-dimensional array, the multiple conductive regions 2011 are also arranged in a two-dimensional array.

[0135] It can be understood that the double-layered conductive region 2011 is a mutual capacitance region. One of the first sub-conductive region 2011a and the second sub-conductive region 2011b can function as a transmitting electrode for emitting an electric field signal, while the other can function as a receiving electrode for receiving the electric field signal emitted by the transmitting electrode, thereby enabling the perception of touch information.

[0136] In some embodiments of the present application, the first sub-conductive layer 201a and the second sub-conductive layer 201b of the conductive layer 201 are both woven from thermoplastic fibers 410 and conductive fibers 500, thereby further reducing the elasticity of the conductive layer 201. In other embodiments, any sub-conductive layer in the conductive layer 201 is woven from thermoplastic fibers 410 and conductive fibers 500. For example, the first sub-conductive layer 201a is woven from thermoplastic fibers 410 and conductive fibers 500, and the second sub-conductive layer 201b is woven from conductive fibers 500.

[0137] Figure 17 illustrates an exemplary structure of the insulating layer 202 in the second sensing portion 200 in an embodiment of the present application. Referring to Figure 17 , in some embodiments of the present application, the insulating layer 202 is woven from thermoplastic fibers 410 and insulating fibers 600. The thermoplastic fibers 410 can restrict relative movement between adjacent insulating fibers 600 after heating and cooling, thereby effectively reducing the elasticity of the insulating layer 202.

[0138] The weaving method between the thermoplastic fibers 410 and the insulating fibers 600 is substantially the same as the weaving method between the thermoplastic fibers 410 and the conductive fibers 500 described above. Therefore, reference may be made to the above description of the weaving method between the thermoplastic fibers 410 and the conductive fibers 500, which will not be repeated here.

[0139] It can be understood that the above embodiment only takes the second sensing part 200 including the conductive layer 201 and the insulating layer 202 arranged in a stacked manner as an exemplary illustration. In other embodiments, the second sensing part 200 may also include a conductive layer 201, but not include the insulating layer 202. The conductive layer 201 is woven together by thermoplastic fibers 410 and conductive fibers 500. The thermoplastic fibers 410 are wrapped around the outer periphery of the conductive fibers 500, and together with the conductive fibers 500, form a fiber group 700, which is woven to form the conductive layer 201. By way of example, Figure 18 shows a schematic cross-sectional view of the fiber group 700 in some other embodiments of the present application. Referring to Figure 18, since the thermoplastic fiber 410 is wrapped around the periphery of the conductive fiber 500, after the fiber group 700 is woven to form a conductive layer (not shown), the user's fingers are in contact with the thermoplastic fiber 410 and do not come into contact with the conductive fiber 500, so it will not affect the generation of the capacitance signal, thereby ensuring that the second sensing part 200 can normally sense the touch information.

[0140] Continuing with Figure 5B , in some embodiments of the present application, the third sensing portion 300 includes two conductive layers stacked along the Z-direction: a first conductive layer 301a and a second conductive layer 301b. An insulating layer 302 is disposed between the first conductive layer 301a and the second conductive layer 301b. Along the Z-direction, the surface of either the first conductive layer 301a or the second conductive layer 301b forms a portion of the inner surface of the fabric 10, while the surface of the other layer forms a portion of the outer surface of the fabric 10. In other words, a user can make contact with either the first conductive layer 301a or the second conductive layer 301b. The first conductive layer 301a and the second conductive layer 301b can form a flat plate capacitor, thereby enabling pressure sensing.

[0141] As mentioned above, in some embodiments of the present application, the third sensing portion 300 may include thermoplastic fibers 410. The thermoplastic fibers 410 can make the third sensing portion 300 have less elasticity to ensure the stability of sensing pressure information.

[0142] In some embodiments of the present application, the first conductive layer 301a is woven together by thermoplastic fibers 410 and conductive fibers 500. The thermoplastic fibers 410 can limit the relative movement between adjacent conductive fibers 500 after heating and cooling, thereby effectively reducing the elasticity of the first conductive layer 301a.

[0143] In some embodiments of the present application, the second conductive layer 301b may also be woven together by thermoplastic fibers 410 and conductive fibers 500. The thermoplastic fibers 410 may limit the relative movement between adjacent conductive fibers 500 after heating and cooling, thereby effectively reducing the elasticity of the second conductive layer 301b.

[0144] Among them, the weaving method between the thermoplastic fibers 410 and the conductive fibers 500 in the first conductive layer 301a and the second conductive layer 301b is substantially the same as the weaving method between the thermoplastic fibers 410 and the conductive fibers 500 in the above-mentioned conductive layer 201. For details, please refer to the relevant description of the conductive layer 201 above and will not be repeated here.

[0145] It is understood that the areas where the conductive fibers 500 are located in the first conductive layer 301a and the second conductive layer 301b also form conductive areas, enabling the third sensing portion 300 to sense different pressure information. Different distribution patterns of the conductive fibers 500 form different numbers of conductive areas, which in turn form different types of planar capacitors, thereby achieving different pressure sensing functions.

[0146] Figure 19 illustrates an exemplary arrangement of conductive regions within the first conductive layer 301a and the second conductive layer 301b in embodiments of the present application. As shown in Figure 19 , in some embodiments of the present application, the first conductive layer 301a includes a first conductive region 3011a. The second conductive layer 301b includes a second conductive region 3011b. The first conductive region 3011a and the second conductive region 3011b are positioned relative to each other along the Z direction, thereby forming a parallel plate capacitor that can be used to sense pressure at a single location.

[0147] In other embodiments of the present application, there may be multiple first conductive regions 3011a and multiple second conductive regions 3011b to form multiple parallel plate capacitors, thereby being able to sense pressure at multiple locations.

[0148] In some implementations, the arrangement of the multiple first conductive regions 3011a and the multiple second conductive regions 3011b can be the same. For example, Figure 20 shows an exemplary arrangement of another conductive region in the first conductive layer 301a and the second conductive layer 301b in an embodiment of the present application. As shown in Figure 20, the multiple first conductive regions 3011a and the multiple second conductive regions 3011b are arranged in a two-dimensional array and in the same arrangement direction. The multiple first conductive regions 3011a and the multiple second conductive regions 3011b correspond one to one. Along the Z direction, the projections of each first conductive region 3011a and the corresponding second conductive region 3011b on the insulating layer 302 overlap with each other, thereby forming a capacitor together. In this way, the third sensing part 300 can have multiple capacitors arranged in a two-dimensional array, so that the pressure at multiple positions in the two-dimensional direction can be sensed.

[0149] For another example, the multiple first conductive regions 3011a and the multiple second conductive regions 3011b can also be arranged in a one-dimensional array, with the same arrangement direction. The multiple first conductive regions 3011a and the multiple second conductive regions 3011b correspond one to one. Along the Z direction, the projections of each first conductive region 3011a and the corresponding second conductive region 3011b on the insulating layer 302 overlap, thereby forming a capacitor. In this way, the third sensing portion 300 can have multiple capacitors arranged in a one-dimensional array, thereby being able to sense pressure at multiple locations in the one-dimensional direction.

[0150] In other implementations, the arrangement of the plurality of first conductive regions 3011a and the plurality of second conductive regions 3011b may be different. For example, the plurality of first conductive regions 3011a and the plurality of second conductive regions 3011b may both be arranged in a one-dimensional array, with the arrangement directions being perpendicular to each other, so that the plurality of capacitors ultimately formed are arranged in a two-dimensional array. The specific implementation is substantially the same as the above-described implementation of forming the plurality of conductive regions 2011 arranged in a two-dimensional array. For details, please refer to FIG. 16A and FIG. 16B and the related descriptions, and are not further described here.

[0151] As previously mentioned, in some embodiments of the present application, the third sensing portion 300 may include elastic fibers 420. The elastic fibers 420 can reduce the compressibility of the third sensing portion 300, thereby enabling the third sensing portion 300 to sense a wider range of pressures. Furthermore, by selecting different elastic fibers 420, the third sensing portion 300 can have varying compressibility, thereby meeting the pressure sensing requirements of different application scenarios.

[0152] Specifically, Figure 21 illustrates an exemplary structure of the insulating layer 302 in the third sensing portion 300 in embodiments of the present application. Referring to Figure 21 , in some embodiments of the present application, the insulating layer 302 is woven from elastic fibers 420 and insulating fibers 600. The elastic fibers 420 effectively enhance the elasticity of the insulating layer 302, thereby providing elastic support for the first conductive layer 301a and the second conductive layer 301b. This, in turn, makes the third sensing portion 300 less susceptible to compression, allowing it to withstand a wider range of pressure.

[0153] The weaving method between the elastic fibers 420 and the insulating fibers 600 is substantially the same as the weaving method between the thermoplastic fibers 410 and the conductive fibers 500 described above. Therefore, reference may be made to the above description of the weaving method between the thermoplastic fibers 410 and the conductive fibers 500, which will not be repeated here.

[0154] In some embodiments of the present application, the woven structure 20 can be woven from insulating fibers 600, thereby preventing mutual conduction between the first sensing part 100, the second sensing part 200 and the third sensing part 300, ensuring that the first sensing part 100, the second sensing part 200 and the third sensing part 300 can operate normally.

[0155] In some embodiments of the present application, the thermoplastic fiber 410 may be any one of polyamide fiber, polyester fiber or polypropylene fiber.

[0156] In some embodiments of the present application, the elastic fiber 420 may be made of any one of polyurethane, polyacrylate or polyester.

[0157] In some embodiments of the present application, the conductive fiber 500 can be any one of carbon fiber, copper wire, silver wire, stainless steel wire, or natural fiber or synthetic fiber coated with a conductive material. The conductive material can be gold, silver, silver nanowire, or copper.

[0158] In some embodiments of the present application, the insulating fiber 600 can be any one of cotton fiber, wool fiber, linen fiber, silk fiber, polyester fiber, spandex fiber, acrylic fiber, aramid fiber, nylon fiber, acrylic fiber, polypropylene fiber, polyester fiber or nylon fiber.
