Abstract

A device which is adapted to transmit electrical energy between an electrical instrument and a living body such as a human body. The device includes a support which has an outer face adapted to be placed in engagement with a surface such as a human skin surface, while the support has an outer periheral edge surrounding the latter outer face thereof and the support being formed inwardly of its outer peripheral edge with an opening extending at least partly into the support from its outer face. An electrically-conductive gel is situated in the latter opening and is at least partly exposed at the outer face of the support so as to be capable of engaging and making electrical contact with the surface which is engaged by the outer face of the support. At least one carbon yarn has a portion situated in this gel for making electrical contact therewith, and an insulation covers the yarn at the region of its portion which is situated in the gel. This insulation is carried by the support so as to support the carbon yarn through the insulation. The yarn together with the insulation have a length sufficiently great to extend through a substantial distance beyond the support, and the yarn carri…
