Patent ID: 7366558

Claim:
An electrode for obtaining a bioelectric signal from the skin of a subject, the electrode comprising: an adhesive element having a bottom surface for attaching the electrode to the skin; an electrode body coupled to the adhesive element; an electrically conductive electrode pad coupled to the electrode body; a sponge element soaked with conductive gel and coupled to a bottom surface of the electrode pad; and abrasion elements integrated with the electrode pad and extending towards the skin when the adhesive element is attached to the skin; the abrasion elements being so dimensioned that the sponge element prevents the abrasion elements from touching the skin when the adhesive element is attached to the skin, and enables mechanical contact between the skin and the abrasion elements when the electrode pad is moved in a direction towards the skin; the electrode body being flexible enough to enable movement of the electrode pad in the direction towards the skin and to also enable movement in a direction horizontal to the skin.
