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.
