[0006] In 2000, E.R. Post of the Massachusetts Institute of Technology introduced a kind of integrated circuit implanted in clothing in the paper "E-broidery: Design and fabrication of textile-based computing". method (as shown in Figure 1), it is used The sewing thread sews the pins of the implant to the substrate of the garment, covered with an insulating layer, and the outermost layer is the surface of the garment, forming a sandwich-like structure, but the integrated circuit implantation process in this structure is not very good, It is very cumbersome, and the sealing is also poor
[0007] Fiber Bragg grating temperature sensors have special features compared with traditional sensors, such as small diameter (125μm), corrosion resistance, optical path can be bent to a certain extent, etc., but bare The mechanical strength of fiber gratings is still very low

Embodiment Construction
[0025] The best embodiment of the present invention will be described in detail below in conjunction with technical solutions and accompanying drawings.
[0026] The schematic diagram of the fabric structure distribution of the fiber grating temperature sensor implanted in the clothing proposed by the present invention is as attached figure 2 shown. The specific method of implantation is to implant the fiber grating temperature sensor into the fabric without damaging the optical fiber and the sensor, without bending, and ensuring that it is consistent with the movement of the warp and weft yarns of the fabric. into the fiber grating temperature sensor. Divide the fabric into three parts, such as figure 2 shown.
[0027] figure 2 In the first part, plain weave is used for ordinary fabrics, and the second part is to realize a part of large tube, which uses the combination of tubular weave and plain weave. Part of the weaving is completed while maintaining the opening of ...

The invention discloses a method for embedding an optical fiber grating temperature sensor into clothes, which is used for detecting human temperature in intelligent clothes and belongs to the technical field of the intelligent clothes. A traditional electrical temperature sensor is easily influenced by outside electromagnetic disturbance and the optical fiber grating sensor for detecting the human temperature is easily broken and easily influenced by outside stress. The invention provides a weaving method for embedding the optical fiber grating temperature sensor into the clothes, avoiding damaging an optical fiber and the sensor by bending, ensuring consistence with the movement of wrap and weft of fabric, combining a large pipe and a small pipe. The invention researches on the method suitable for weaving an optical fiber grating to enhance a success rate in an embedding process, avoids breaking the optical fiber grating, and provides a guidance method for embedding more kinds of sensors into the intelligent clothes.
Description
technical field [0001] The invention belongs to the technical field of smart clothing, and in particular relates to a method for implanting an optical fiber grating temperature sensor used in smart clothing to detect human body temperature into clothing. Background technique [0002] Smart clothing is the product of the combination and intersection of electronic information, materials, textiles and other related disciplines. It can monitor changes in the external environment or internal state of the human body, and has the characteristics of easy portability and real-time monitoring. Smart clothing can not only perceive changes in the external environment or internal state of the human body, but also respond to such changes in real time through a feedback mechanism. Perception, feedback and reaction are the three elements of smart clothing. [0003] At present, there are mainly two methods for detecting human body temperature: contact measurement and non-contact measuremen...
