Skin electrode with a by-pass element
First Claim
1. 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, andan 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.

Abstract
The present invention concerns an electrode for establishing electrical contact with the skin. The electrode comprises an electrically conductive gel (12) covering a part of a first side of an electrically conductive layer (4) and an electrically conductive by-pass element (19). The by-pass element extends, on the second side of the electrically conductive layer, over the circumference of the gel on the first side and is in electrical contact with the second side of the electrically conductive layer at a point opposing an area covered with electrically conductive gel at the first side of the electrically conductive layer. The by-pass element ensures that the electrode continues to be operable even if exposed to chemical or mechanical stress.
