Patent ID: 7146228

Claim:
An electrode for establishing electrical contact with skin, comprising: an electrically conductive layer provided with means for establishing electrical connection to an apparatus for supplying or measuring electrical signals, and an electrically conductive gel covering a part of a first side of the electrically conductive layer so that the circumference of the electrically conductive gel at least partly crosses the surface of the first side of the electrically conductive layer, wherein an electrically conductive by-pass element provided with means for establishing electrical connection to said apparatus for supplying or measuring electrical signals, on the second side of the electrically conductive layer, is provided so that it extends over at least a part of said second side opposing the circumference of the gel crossing the surface of the electrically conductive layer on the first side and is in electrical contact with the second side of the electrically conductive layer at at least one point opposing an area covered with the electrically conductive gel at the first side of the electrically conductive layer.
