Abstract:
1. A method for producing an electrode structure ( 10 ) for implants, comprising a noble metal or a noble metal alloy having a thickness of ≦100 μm, wherein the electrode structure ( 10 ) has an electrode core ( 12 ) comprising an element selected from the group consisting of gold, silver, copper, and alloys of at least two of these elements, and wherein the electrode core ( 12 ) has a thickness in a range of about 5 μm to 99.8 μm and is encased completely by a first coating ( 13 ; 13 a , 13 b ) comprising at least one element selected from the group consisting of platinum, iridium, and ruthenium, the method comprising: a) coating an electrically insulating surface ( b) galvanically generating a first part ( c) galvanically forming the electrode core ( d) then removing the structured photoresist ( e) removing the metal layer ( f) galvanically coating part of the electrode core ( g) detaching the electrode structure ( h) then removing the metal layer (
