Abstract
An electrode for obtaining a biopotential signal from the skin of a subject. The electrode comprises an adhesive element, an electrode body, an electrically conductive electrode pad, a sponge element, soaked with conductive gel, and means for skin abrasion. The means for skin abrasion comprises abrasion elements forming an integrated structure with the electrode pad, the abrasion elements being so dimensioned that the sponge element prevents the abrasion elements from touching the skin when biopotential signals are measured and enables mechanical contact between the skin and the abrasion elements when the electrode pad is pushed towards the skin. The electrode body is made flexible to enable intentional movement of the electrode pad relative to the adhesive element.
