Electrically conductive, visco-elastic gel and its use in electrode

A visco-elastic gel comprising a high molecular weight polysaccharide, at least one polyol and, optionally, at least one non-volatile acid soluble in the polyol and at least one non-volatile base soluble in the polyol. The polyol has a water content of 5 to 20 percent by weight and the various compo...

Beschreibung
Zusammenfassung:	A visco-elastic gel comprising a high molecular weight polysaccharide, at least one polyol and, optionally, at least one non-volatile acid soluble in the polyol and at least one non-volatile base soluble in the polyol. The polyol has a water content of 5 to 20 percent by weight and the various components set forth are physiologically acceptable. The gel is particularly suitable as a means for releasably securing an electrode to the skin as, for example, when taking an EEG or EKG. Methods of making a suitable electrode and using it are also disclosed.
