To use, the electrically conductive layer is attached to human skin surface to detect a signal generated by the human body. However, the electrically conductive 11 of such a detection element 1 is generally of poor resiliency and has poor electrical conductivity with human skin is poor, making it difficult to detect the signal generated by the human body and also making wear uncomfortable. As shown in Figure 2, an improvement is made such that a resilient layer 12 is arranged between the electrically conductive layer 11 and the base layer 10 so that contact tightness between the electrically conductive layer 11 and human skin can be improved with the resilient layer 12. Further, a moisture-retaining material is also included in the layer to make the layer also function moisture retaining thereby improving electrical conductivity of the electrically conductive layer 11. However, since the resilient layer 12 and the electrically conductive layer 11 are two separate layers, moisture must penetrate through the electrically conductive layer 11 before being absorbed by the resilient layer 12. Consequently, the absorbability of moisture is affected. When the resilient layer 12 releases water between the electrically conductive layer 11 and human skin, the release of water is also affected by being blocked by the electrically conductive layer 11. Further, since the resilient layer 12 and the electrically conductive layer 11 are two separate layers that are bonded to each other by an external force (such as adhesion). These layers are easily detached from each other due to the high humidity long maintained by the resilient layer 12, making the detection element 1 losing its function. However, said method is to stick the detection element 1 to a garment.

  • Referring to Figure 3 and figure 4, which is a perspective view showing, in an enlarged form, a portion of the fabric pressure switch in accordance with the present invention, as shown in the drawing, the first resilient conductive tissue 20 is formed by arranging and interlacing, through proper fabric manufacturing process, a plurality of first structural yarns 200, a plurality of first elastic yarns 201, and a plurality of first electrically conductive yarns 202 together. Each of the first structural yarns 200 is combined with each of the first elastic yarns 201 as a strand for being arranged alternately with each of the first electrically conductive yarns 202. Further, the first structural yarns 200, the first elastic yarns 201, and the first electrically conductive yarns 202 are alternately arranged through knitting to form the resilient conductive tissue 20. The second resilient conductive tissue 40 is formed by arranging and interlacing a plurality of second structural yarns 400, second elastic yarns 401, a plurality of second elastic yarns 401, and a plurality of second electrically conductive yarns 402 together. Each of the second structural yarns 400 and each of the second elastic yarns 401 are arranged together as the same strand for being arranged alternately with each of the second electrically conductive yarns 402. The support tissue 30 is formed of a plurality of first support yarns 300 and a plurality of second support yarns 301 and connects between the resilient conductive tissue 20 and the second resilient conductive tissue 40, wherein each of the first support yarns 300 is arranged, as the same strand, with each of the first structural yarns 200 and each of the first elastic yarns 201 and subsequently extends to the second resilient conductive tissue 40 to be arranged, as the same strand, with each of the second structural yarns 400 and each of the second elastic yarns 401.

The interlaced arrangement of the first support yarns 300 and the second support yarns 301 provides improved resiliency to the fabric pressure switch of the present invention, so as to make a wearer comfortable when is used to make a wearable article.
  • Referring to Figure 4, which is a perspective view showing, in an enlarged form, a portion of the fabric pressure switch in accordance with the present invention, as shown in drawing, the first resilient conductive tissue 20 is formed by arranging and interlacing a plurality of first structural yarns 200, a plurality of first elastic yarns 201, and a plurality of first electrically conductive yarns 202 together. Each of the first structural yarns 200 is combined with each of the first elastic yarns 201 as a strand for being arranged alternately with each of the first electrically conductive yarns 202, whereby after the entirety of the fabric pressure switch is completely arranged when the stretching force of yarns are removed, the first elastic yarns 201 get contracting and squeeze the electrically conductive yarns 202 outward so that the electrically conductive yarns 202 project beyond the surface of the entire resilient conductive tissue 20. This ensures that when the fabric is placed on human body, the first electrically conductive yarns 202 get contact with the human body first so that the fabric pressure switch according to the present invention may provide improved effect of detection.

Therefore, a signal receive and illustrious device (not shown in Fig. 5) electrically connect to the first resilient conductive tissue 20 and the second resilient conductive tissue 40 would detect the pressure in which the fabric pressure switch was taken. Moreover, when the pressure removes from the fabric pressure switch and return to the original condition, as shown in Figure 3, the first resilient conductive tissue 20 and the second resilient conductive tissue 40 are separated by the elasticity of the support tissue 30 and formed a broken circuit. Therefore, the signal receive and illustrious device will detect a signal in which the pressure was removed.

If the first structural yarns 200 and the second structural yarns 400 are selected from these four materials, then the fabric pressure switch according to the present invention may shows the characteristics of resiliency, moisture retention, and electrical conductivity.
  • The first elastic yarns 201 and the second elastic yarns 401 can be spandex yarn.
