Please see Figure 1D again, the conductive yarn module shown in Figure 1D 100 overall schematic diagram. In order to clearly show the relationship between the elements and the layers of the conductive yarn module 100 , the elements or layers of the conductive yarn module 100 in FIG. 1D are not drawn according to actual scale.

Since the operating conditions of the electronic device 150 are related to its load impedance, the load impedance may include the impedance values of the first conductive layer 110 and the second conductive layer 120. Therefore, the first conductive layer 110 and the second conductive layer 120 will The yarn 102 is extended so that its resistance value can be adjusted to suit the operating conditions of the electronic components.

Further, the yarn 102 has opposite first ends T1 and second ends T2.
