Abstract

The invention relates to an electronic textile comprising a textile substrate having a substrate electrode, and an electronic component having a component electrode. The component electrode is in electrically conductive contact with the substrate electrode via a coupling layer having a directionally dependent conductance so as to preferentially allow an electrical current to flow between the substrate electrode and the component electrode. As the coupling layer does not have to be patterned to prevent the occurrence of parasitic electrical currents, the electrically conductive contact between the substrate electrode and the component electrode has an improved reliability.

Claims

1. An electronic textile comprising a textile substrate having a substrate electrode, and an electronic component having a component electrode, the component electrode being in electrically conductive contact with the substrate electrode via a coupling layer comprising an anisotropically conductive material, wherein the substrate electrode comprises an electrically conductive yarn, and wherein the anisotropically conductive material is an outer layer of the electrically conductive yarn.

2. The electronic textile according to claim 1, wherein the anisotropically conductive material comprises an electrically insulative binder and electrically conductive particles.

3. The electronic textile according to claim 2, wherein the electrically conductive particles are elastic.

4. The electronic textile according to claim 2, wherein the electrically insulative binder comprises a compound chosen from the group consisting of thermosetting and thermoplastic synthetic resins.

5. The electronic textile according to claim 1, wherein the electronic component comprises a clamping member.
