CLAIMS

What is claimed is:

1. A method that uses a needle-directing machine having at least a needle, a needle bar, a head, an arm, and a processor that executes computer readable program instructions, the method being for attaching to a fabric having a thickness an electronic circuit arranged on a patch, the method comprising:

stitching a circuit to the fabric with anisotropic conductive thread having electrically conductive segments and electrically insulating segments;

wherein stitching the circuit to the fabric proceeds according to a predetermined path representing a pattern the anisotropic conductive thread travels through the fabric thickness to attach the patch to the fabric, and laterally across the fabric; and

further comprising, before the step of stitching the circuit to the fabric, storing, on a computer readable medium, program instructions that when executed by the processor configure the predetermined path for stitching the anisotropic conductive thread into the fabric such that only electrically conductive segments of anisotropic conductive thread travel through the fabric thickness where the patch is attached to the fabric.

2. The method of claim 1, further comprising causing the processor to execute the program instructions, thereby stitching the anisotropic conductive thread to the fabric according to the predetermined path.

3. The method of claim 1, further comprising forming holes in the patch through which only electrically conductive segments of anisotropic conductive thread pass.

4. The method of claim 1, wherein the fabric has at least one seam that separates a first side of the fabric from a second side of the fabric, and further comprising configuring the predetermined path to stitch anisotropic conductive thread from fabric on the first side of the at least one seam to fabric on the second side of the at least one seam.

5. The method of claim 1, wherein the electrically conductive segments and electrically insulating segments are alternating.

6. The method of claim 1, further comprising forming anisotropic conductive thread by sensitizing selected areas of non-conducting thread for plating, and then exposing the sensitized thread to a solution that contains silver nitrate.

7. A method that uses a needle-directing machine having at least a needle, a needle bar, a head, an arm, and a processor that executes computer readable program instructions, the method being for attaching to a fabric having a thickness a plurality of electronic circuits each being arranged on a patch, the method comprising:

stitching two or more circuits to the fabric with anisotropic conductive thread having electrically conductive segments and electrically insulating segments;

wherein stitching the circuits to the fabric proceeds according to a predetermined path representing a pattern the anisotropic conductive thread travels through the fabric thickness to attach each patch to the fabric, and laterally across the fabric;

wherein the electrically insulating segments are arranged such that an electrical connection is not formed between any two circuits; and

further comprising, before the step of stitching the circuit to the fabric, storing, on a computer readable medium, program instructions that when executed by the processor configures the predetermined path for stitching the anisotropic conductive thread into the fabric such that (i) only electrically conductive segments of anisotropic conductive thread travel through the fabric thickness where each patch is attached to the fabric, and (ii) at least one electrically insulating segment travels across the fabric between any two patches.

8. The method of claim 7, further comprising causing the processor to execute the program instructions, thereby stitching the anisotropic conductive thread to the fabric according to the predetermined path.

9. The method of claim 7, further comprising forming holes in the patch through which only electrically conductive segments of anisotropic conductive thread pass.

10. The method of claim 7, wherein the fabric has at least one seam that separates a first side of the fabric from a second side of the fabric, and further comprising configuring the predetermined path to stitch anisotropic conductive thread from fabric on the first side of the at least one seam to fabric on the second side of the at least one seam.

11. The method of claim 7, wherein the electrically conductive segments and electrically insulating segments are alternating.

12. The method of claim 7, further comprising forming anisotropic conductive thread by sensitizing selected areas of non-conducting thread for plating, and then exposing the thread to a solution that contains silver nitrate.

13. An article formed from a fabric, comprising:

at least two patches each being formed from a flexible substrate and each patch having an electronic circuit formed thereon;

wherein each circuit is electrically and mechanically connected to the article with anisotropic conductive thread having alternating electrically conductive segments and electrically insulating segments;

such that at least one electrically conductive segment passes through the substrate in a direction along a first spatial dimension and at least one insulating conductive segment extends between the at least two circuits moving in a second spatial dimension.

14. The article of claim 13, wherein the fabric forming the article has at least one seam that separates a first side of the fabric from a second side of the fabric, and wherein the anisotropic conductive thread is stitched from fabric on the first side of the at least one seam to fabric on the second side of the at least one seam.

15. The article of claim 13, further comprising a multi-pin electrical connection formed integrally with at least one of the circuits arranged for electrical connection to a printed circuit board.
