1. A medical electrode comprising:
- a backing member having an adhesively coated surface, sensor means affixed to said backing member and being of a lesser overall dimension such that said adhesively coated surface of the backing member is exposed about a substantial portion of the periphery of said sensor means, said sensor means being formed of an electrically conductive material and having a flat, electrically condutive surface portion for engagement with the skin of a patient, and an electrically conductive coating applied to selected areas of said flat surface portion of said sensor means such that areas of said surface portion other than said coated selected areas are substantially free of said conductive coating, thereby defining a predetermined pattern on said flat surface portion of said sensor means of areas having said conductive coating applied thereto and areas substantially free of said conductive coating, respectively, such that upon application of the electrode to a patient the exposed portion of said adhesively coated surface of the backing member will hold the sensor means in contact with the patient'"'"'s skin whereby those areas of said surface portion that are free of said conductive coating will be brought into electrically conductive surface-to-surface contact with the patient'"'"'s skin, while the coated areas of said surface portion will be in electrical contact with the patient'"'"'s skin by means of said conductive coating.

Abstract
A medical electrode comprises a flat, resilient, electrically non-conductive backing member; a flat sensor element applied to one surface of the backing member and positioned for leaving a portion of this one surface exposed about a major portion of the periphery of the sensor element; and an electrically conductive coating applied to selected areas of the exposed surface of the sensing element.

16. A medical electrode comprising:
- a sensor element formed of an electrically conductive and having a flat, electrically conductive surface portion for engagement with the skin of a patient, and an electrically conductive coating applied to selected areas of said flat surface portion of said sensor element such that areas of said surface portion other than said coated selected areas are substantially free of said conductive coating, thereby defining a predetermined pattern on said flat surface portion of said sensor element of areas having said conductive coating applied thereto and areas substantially free of said conductive coating, respectively, said conductive coating comprising an electrically conductive, pressure sensitive adhesive material, with at least one or more of said uncoated areas being disposed intermediate an area or areas having said conductive adhesive thereon such that upon application of the electrode to a patient the pressure sensitive adhesive will hold the surface portion of said sensor element in contact with the patient'"'"'s skin with those areas of the surface portion that are free of said conductive coating being held in electrically conductive surface-to-surface contact with the patient'"'"'s skin, while the coated areas of the surface portion will be in electrical contact with the patient'"'"'s skin by means of said conductive adhesive coating.
