Abstract

A composition providing electrically conductive adhesive hydrogels suitable for use as skin contact adhesives and, particularly, suitable for use as an electrical interface for disposable medical devices. The present hydrogels provide for reduced skin irritation and/or malodor properties, hydrate a subject's skin, readily wet around a subject's skin surface hair, and protect against burning of a subject upon or due to electrical stimulation through the hydrogel. These hydrogels generally include a monomer, a first initiator, a solubilizer, and a cross-linking agent. The present hydrogels also desirably include a buffer system to help prevent discoloration of the hydrogels and/or hydrolysis of the hydrogels as well as to improve shelf-life. Other additives such as conductivity enhancers, pharmaceuticals, humectants, plasticizers, skin health agents, etc. may be added to the present hydrogels either before or after curing.
