Abstract
Abstract An electrolyte for a bio-electric event measuring electrode combines a salt with adhesive. The adhesive serves as the vehicle for dispersing solvent to form the electrolyte in a solid or semisolid mixture. The adhesive serves further as a structural element in holding the parts of a practical electrode together and in making the electrode adhere to a subject's skin.
