In this embodiment, the signal yarn 110 is a single signal yarn, so the number of the signal units 113 is determined by the number of the turning units 112, and the number of the turning units 112 is determined according to the requirement (e.g., the sensing sensitivity). In one embodiment, the distance between the two signaling units 113 is 1 millimeter (micrometer), and the application is not limited thereto, and the distance between the two signaling units 113 can be determined according to the requirement (e.g., sensing sensitivity).

The single core wire 120 is disposed in the yarn sensor section 111 and intersects with the signal unit 113. In this embodiment, the single core wire 120 extends in the second direction d2 and is perpendicular to the communication unit 113.

In this embodiment, the communication yarn 110 and the single core thread 120 are fixed to a fabric 130 by sewing, wherein the fabric 130 is, for example, a woven fabric woven by ordinary yarn. In one embodiment, the fabric 130 is a quadrilateral, and has a side length of 30 millimeters (millimeter), but the present application is not limited thereto.

In this embodiment, the sensing signal may be output by one of the communication yarn 110 or the single core wire 120.

Referring to fig. 2, fig. 2 is a schematic view of a sensor element 2 according to another embodiment of the present application, and the sensor element 2 includes a plurality of communication yarns 210 and a single core wire 220.

The single core wire 220 is formed with a single core wire sensing part 221, the single core wire sensing part 221 includes at least one turning unit 222 and at least two single core units 223 connected to the at least one turning unit 222, the turning unit 222 is connected to the two single core units 223, wherein the at least two single core units 223 are arranged in the first direction d1 and are parallel to the second direction d2, and the first direction d1 is perpendicular to the second direction d 2. In this embodiment, the single core line 220 is used to output the sensing signal.

The plurality of the communication yarns 210 extend in the first direction d1 and are aligned in the second direction d2, are disposed in the single core sensing part 221, and intersect with at least two single core cells 223, for example, each communication yarn 210 may be approximately perpendicular to at least two single core cells 223.

In this embodiment, the plurality of the communication yarns 210 and the single core thread 220 are fixed to a fabric 230 by sewing, wherein the fabric 230 is, for example, a woven fabric woven by ordinary yarns. In one embodiment, the fabric 230 is a quadrilateral with a side length of 30 millimeters (millimeter), but the application is not limited thereto.

In the sensing element 1(2) of the present embodiment, a capacitance may be formed between the communication yarn 110(210) and the single core wire 120(220), and when an object (e.g., a finger) approaches or touches the sensing element (sensing event), the capacitance may change due to the electric field changed by the approach or touch of the object. Therefore, by using the scanning signals received by the sensing elements 1 and 2 and the sensing signals correspondingly generated, whether the capacitance value changes can be determined according to the sensing signals, so as to further determine whether a sensing event (an object approaches or touches the sensing element) occurs.

In an embodiment, the single core wire 120(220) may be formed by coating a copper-tin alloy with an insulating layer, the insulating layer may be made of insulating paint, such as one of teflon, polyethylene terephthalate, fluoroplastic film, polyvinyl chloride, polyethylene, and other polymer insulating materials, and the application is not limited thereto.

Referring to fig. 3 and 4, fig. 3 and 4 are schematic diagrams of a yarn 300 according to an embodiment of the present application, the yarn 300 includes a short woven fiber 310 and a sheet-like conductor 320, and the short woven fiber 310 is used as a brace to support the sheet-like conductor 320 around the short woven fiber. The sheet conductor 320 surrounds the circumferential surface of the spun fiber 310 in a spiral progression. The sheet-like conductor 320 may increase the tear strength of the yarn 300 by surrounding the surrounding surface of the woven staple fiber 310 in a spiral progression.

Alternatively, the strength of the pull-resistant portion of the communication yarn 300 can be further increased by selecting the strength of the woven fabric 310 and/or the length-to-width ratio of the transverse cross-section of the sheet-like conductor 320 corresponding to the spiral travel pattern. In this embodiment, the strength of the short woven fiber 310 is selected to be 30, and the length-width ratio of the transverse section of the sheet conductor 320 corresponding to the spiral traveling manner is selected to be about 20, but the present application is not limited thereto. For example, the strength of the short woven fiber 310 may be selected to be 26, 28 or 40, or the length-width ratio of the sheet-like conductor 320 corresponding to the transverse cross section of the spiral traveling manner may be selected to be about 10 to 30.

The type of alloy may be chosen differently in different applications.

Fig. 5 is a schematic structural diagram of a sensing control system according to an embodiment of the present application. The sensing control system 4 comprises a sensing element 410, and a control module 420 comprising a sensing control module 421 and a central control module 422.

The sensing control module 421 is used for generating a scanning signal provided to the sensing element 410, receiving a sensing signal generated by the corresponding scanning signal, and providing a sensing result according to the sensing signal. In an embodiment, the sensing control module 421 is a capacitive sensing chip, and the application is not limited thereto.

The central control module 422 is electrically connected to the sensing control module 421, and is configured to receive the sensing result and determine whether to control an electrically connected component 5 or perform a corresponding operation according to the sensing result. For example, the central control module 422 determines whether a sensing event occurs according to the sensing result, and the central control module 422 determines that a sensing event occurs, so as to control the component 5. In one embodiment, the central control module 422 is a control circuit, and the application is not limited thereto.

In one embodiment, the sensing element 410 may be disposed in an electronic device such as a smart phone, and the central control module 422 may perform corresponding operations according to the sensing result. For example, when the central control module 422 determines that a sensing event occurs, the central control module 422 causes the smart phone to display a locked state screen.

In one embodiment, the component 5 is, for example, a bluetooth communication module. Therefore, in this embodiment, the central control module 422 can control the bluetooth communication module to perform corresponding operations according to the sensing result. For example, the central control module 422 determines that a sensing event occurs, and the central control module 422 enables the bluetooth communication module to send a signal and establish a communication connection with an electronic device, such as a smart phone, which is not limited by the present disclosure.

In one embodiment, the element 5 is, for example, a heating fabric, which comprises at least one resistive element. Therefore, in this embodiment, the central control module 422 can control the heating fabric to be heated according to the sensing result. For example, the central control module 422 determines that a sensing event occurs, and the central control module 422 can provide current to the resistive elements in the heating fabric, so that the resistive elements start to increase in temperature by the current flowing through the resistive elements, so as to start heating the heating fabric.

In one embodiment, the sensing and control system 4 may be configured in a smart fabric, and the application is not limited thereto. As shown in fig. 6, the sensing element 410 may be disposed on the smart fabric 6 near the arm or the palm, and electrically connected to the control module 420 through a communication yarn or other conductive wires, so that the user can conveniently perform the above-mentioned different operations (for example, the smart fabric starts heating up and heating up by sensing with the sensing element 410 and controlling the heating fabric) by touching or approaching the sensing element with the finger or the palm, and the application is not limited to the above-mentioned operations.

In one embodiment, to avoid the occurrence of an event that the sensing element 410 is touched by mistake and causes the sensing control system 4 to perform a corresponding operation, the central control module 422 continuously determines that the sensing event occurs, and after the time for continuously determining that the sensing event occurs exceeds 3 seconds, the central control module 422 controls the element 5 or performs a corresponding operation to ensure that the sensing control system 4 operates correctly according to the operation of the user, wherein the 3 seconds is merely an example, and the number of seconds is not limited in the present application.

In summary, since the sensing element of the embodiment of the present application can be completed by only the communication yarn and the single core wire, the manufacturing complexity and the overall volume of the sensing element are greatly reduced. In addition, the signal yarn has better anti-pulling capability, so the sensing element can be configured on a flexible material, the application range of the sensing element is greatly improved, and the sensing element can be flexibly configured, so the commercial value and the use convenience of the sensing element are further improved.

The above description is only an example of the present application, and is not intended to limit the scope of the present application.
