Abstract

Embodiments relate to conductive textiles and methods of their production, as well as systems for electronically connecting devices through conductive textiles. An example textile comprises a first electrically conductive track; a second electrically conductive track; and at least one non-conductive portion. At least a portion of the first electrically conductive track overlaps or is in close proximity to at least a portion of the second electrically conductive track. At least said portions of the respective tracks are separated by an insulating material so that there is no electrical coupling between the first and second tracks.

First claim

The invention claimed is:

1. A textile comprising:
a first electrically conductive track;
a second electrically conductive track; and
at least one non-conductive portion;
wherein at least a portion of the first electrically conductive track overlaps or is in proximity to at least a portion of the second electrically conductive track;
wherein at least said portion of the first electrically conductive track and said portion of the second electrically conductive track are separated by an insulating material so that there is no electrical coupling between the first and second tracks;
wherein each track comprises a bundle of conductive filaments;
wherein each conductive filament is less than 140 microns thick; and
wherein each bundle comprises at least 100 conductive filaments.

2. The textile of claim 1 , wherein the first track overlaps or is in proximity to the second track at an angle of between 45° and 135°.

3. The textile of claim 1 , wherein the insulating material is dissolvable by heat or a chemical substance to provide electrical coupling between said portions of the first and second tracks, without dissolving the non-conductive portion.

4. The textile of claim 1 , wherein each of the first and second electrically conductive tracks comprises between one and twenty bundles of conductive filaments.

5. The textile of claim 1 , comprising at least three electrically conductive tracks, wherein the tracks comprise at least a signal track, a power in track, and a power out track.

6. The textile of claim 5 , wherein the signal track is configured to be able to transmit digital and/or analogue data signals.

7. The textile of claim 5 , wherein the signal track is configured to be able to transmit data at a speed of between 100 MHz and 1000 MHz.

8. The textile of claim 5 , wherein the signal track, the power in track and the power out track are electrically coupled to a connector.

9. A textile comprising:
at least two electrically conductive tracks; and
at least one non-conductive portion;
wherein the at least two electrically conductive tracks are separated from each other by the at least one non-conductive portion;
wherein each track comprises a bundle of conductive filaments;
wherein each conductive filament is less than 140 microns thick; and
wherein each bundle comprises at least 100 conductive filaments.

10. The textile of claim 9 , wherein each bundle comprises between 100 and 1000 conductive filaments.

11. The textile of claim 9 , wherein each conductive filament is between 10 and 140 microns thick.

12. A layered textile comprising:
a first layer comprising the textile of claim 1 ; and
second and third layers comprising an electromagnetically shielding material;
wherein the first layer is between the second and third layers.

13. The layered textile of claim 12 , further comprising fourth and fifth layers comprising a waterproof material, wherein the first, second and third layers are between the fourth and fifth layers.
