Being the non-conducting backing material, at least one which penetrates completely the surface and this non-conducting backing material channel and, adjoining to the portion of the surface of the non-conducting backing material and the non-conducting backing material which it has, being laid out, penetrating completely the channel and extending being present, in order to join to power source electrically, the conductive trace material adaptation and, it is inactive or or more corrosion-resistant the high 2nd than the trace material and 3rd conductive material and, it includes, the electrode. The 2nd material adjoins to the surface of the trace material, surface the whole this is overturned and is laid out, adjoins the 3rd material, to the surface of the 2nd conductive material, surface the whole this is overturned and is laid out, covers the portion of the surface of the non-conducting backing material which at the same time surrounds the 2nd conductive material. It adjoins the electrode, to the portion of the surface of the 3rd conductive material, but from the trace material the offset doing in cross direction, it was laid out, the conductive hydrogel is included, furthermore.非導電性基材であって、上面と、この非導電性基材を貫通する少なくとも1つのチャネルと、を備える非導電性基材と、非導電性基材の上面の一部に隣接して配置され、チャネルを貫通して延在して、電源に電気的に結合するように適合された導電性トレース材料と、不活性であるか又はトレース材料より耐腐食性の高い第2及び第3の導電性材料と、を含む、電極。第2の材料は、トレース材料の上面に隣接し、この上面全体を覆って配置され、第3の材料は、第2の導電性材料の上面に隣接し、この上面全体を覆って配置され、かつ第2の導電性材料を囲む非導電性基材の上面の一部を覆う。電極は、第3の導電性材料の上面の一部に隣接するが、トレース材料から横方向にオフセットして配置された、導電性ヒドロゲルを、更に含む。
