Abstract
A method of preparing an improved medical electrode particularly adaptable to tape-like configurations for use in sensing and stimulation applications in which the electrode is applied to the skin. An essential electrode component comprises a mixture of a polymerized form of 2-acrylamido-2-methylpropanesulfonic acid or one of its salts with water and/or an alcohol. The mixture possesses electrically conductive properties, flexible properties and adhesive properties particularly lending itself to skin contact and adhesion.
Claims16
A method of preparing a conductive member for an electrode, the member containing as an essential component a polymer selected from the group consisting of 2-acrylamido-2-methylpropanesulfonic acid, its salts, copolymers of the acid, copolymers of the salts of the acid and mixtures thereof wherein the polymer component is formed simultaneously with the formation of the member.
A method of preparing conductive material for skin contacting electrodes comprising:
- dissolving a polymerizable material selected from the group consisting of 2-acrylamido-2-methylpropanesulfonic acid, its salts and mixtures thereof in a solvent selected from the group consisting of water, alcohols and mixtures thereof, and
- polymerizing the polymerizable material in the solvent to form the conductive material.
The method of preparing a medical electrode, comprising the steps:
- providing a quantity of a material selected from the group consisting of 2-acrylamido-2-methylpropanesulfonic acid, its salts, copolymers of the acid, copolymers of the salts of the acid and mixtures thereof;
- polymerizing the material to form a tacky conductive body, and
- attaching electrical lead means to the body.
