the functional wire with the structure shown in fig. 3 is adopted as the temperature sensing element 1 and the conducting wire 4, the distance between the adjacent metal wires 6 in the same horizontal line is enlarged in fig. 3, and the distance is reduced and cannot be contacted with each other along with the increase of the coating degree in the actual preparation process. The temperature sensing element 1 is wrapped outside spandex fibers by adopting platinum fibers, and the lead 4 is wrapped outside the spandex fibers by adopting copper fibers. The outer layers of the temperature sensing element 1 and the lead 4 are coated with polydimethylsiloxane coatings to enhance the wear resistance thereof.
Integrated weaving of an integrated temperature sensing network:
a certain length of yarn is reserved in advance at the position where the yarn of the temperature sensing element 1 and the yarn of the lead 4 are contacted with each other, and the yarn is connected together in a wrapping and consolidation mode to form a wrapping and consolidation area 2. As shown in fig. 4.
The warp yarns and the weft yarns of the fabric substrate 3 are cotton yarns, 2-over-3-down twill weave is adopted, and weaving parameters are set to be straight-through; reed number: 46, each reed 2 penetrates. Weaving by using an SGA598 type semi-automatic sample loom. In the process of weaving the substrate, the temperature sensing element 1 yarns are introduced into a specific position of a temperature sensing area to be taken as weft yarns to be integrally woven, and a plurality of cotton yarn weft yarn intervals are arranged between every two adjacent weft yarns of the temperature sensing element to prevent the temperature sensing element yarns from contacting with each other. The thread of the conducting wire 4 is also integrally woven into the corresponding position as a weft in the same manner. The structure of the integrated temperature sensing network 14 is shown in fig. 1.
The wires in the integrally woven integrated temperature sensing network 14 may be connected directly or indirectly to a data acquisition system for real-time temperature measurement.
Example 2:
if the temperature sensing network is possibly applied to the condition that the stretching and bending effects are far beyond the normal human body stretching deformation range, the elasticity of the substrate can be considered to be increased. Therefore, the warp yarns of the fabric substrate 3 can be made of the nylon/spandex wrapped yarns, the weft yarns are still made of cotton yarns so as to be beneficial to exposing the temperature sensing element yarns on the surface of the fabric, and other yarns are integrally woven according to the method.
Example 3:
because the integrated temperature sensing network is integrally woven, the arrangement mode of a plurality of sensing areas can be designed before weaving according to the requirement of practical application, and the integrated weaving is carried out according to a designed upper computer drawing. FIG. 5 is an integrally woven array temperature sensing network having a first sensing element 10, a second sensing element 11, and a third sensing element 12 woven on a fabric substrate 3; s1, S2, and S3 are signal lines corresponding to the respective sensing regions; g is the ground line.
Example 4:
when a larger sensing area is needed in practical application, a matrix arrangement mode of an integrated woven integrated temperature sensing network can be adopted, as shown in fig. 6.
Example 5:
since the integrally woven integrated temperature sensing network has excellent flexibility, curved surface fitting property and air permeability, the integrally woven integrated temperature sensing network can be applied to the joint area of the human body to play a role, as shown in fig. 7, a schematic diagram of an integrally woven integrated temperature sensing network 14 is used at the position of a human leg 13; the fabric substrate 3 is woven with a sensing element; s1, S2, S3, and S4 are signal lines corresponding to the respective sensing regions; g is the ground line.
