Abstract

A conductive textile is provided, including warp and weft, and the warp and the weft are interwoven. The warp includes a signal-transmitting unit, an electrical connecting unit, and at least a first warp conductive fiber. The signal-transmitting unit consists of a first signal-transmitting cable and a second signal-transmitting cable, which are intertwined. Each of the first signal-transmitting cable and the second signal-transmitting cable includes a central conductive fiber and an outer insulating layer. The electrical connecting unit consists of a first power cable and a second power cable. The first warp conductive fiber is disposed between the signal-transmitting unit and the electrical connecting unit. The weft includes a weft conductive fiber.

Claims

an electrical connecting unit consisting of a first power cable and a second power cable; and

at least a first warp conductive fiber disposed between the signal-transmitting unit and the electrical connecting unit; and

weft comprising;

a weft conductive fiber, and the warp and the weft interwoven.

2. The conductive textile of claim 1, wherein the amount of the first warp conductive fiber is 2.

3. The conductive textile of claim 1, wherein the materials of the central conductive fiber, the first warp conductive fiber and the weft conductive fiber are individually selected from silver, copper, carbon black, graphite, graphene, stainless steel, polyaniline or Polyethylenedioxythiophene (PEDOT:

5. The conductive textile of claim 1, wherein the warp further comprises at least a first warp insulating fiber disposed between the signal-transmitting unit and the electrical connecting unit.

6. The conductive textile of claim 5, wherein the first warp insulating fiber is arranged between at least two of the first warp conductive fibers.

7. The conductive textile of claim 1, wherein the individual outside of the signal-transmitting unit and the electrical connecting unit has at least a second warp conductive fiber disposed thereon, and at least a second warp insulating fiber is disposed between the second warp conductive fiber and the signal-transmitting unit or the electrical connecting unit.

8. The conductive textile of claim 1, wherein the individual outside of the signal-transmitting unit and the electrical connecting unit has at least a third warp conductive fiber disposed thereon, and the third warp conductive fiber is directly adjacent to the signal-transmitting unit or the electrical connecting unit.
