Interface structures for bioelectrodes

Abstract

This disclosure relates to a bioelectrode comprising an electrode structure having a carrier, a conductive element, and an adhesive layer forming the outermost surface of the electrode structure, and a skin interface structure provided on the outermost surface of the electrode structure and including a conductive film having at least one opening. An advantage of using a skin interface structure in the electrode structure is that the quality of the measured signal may be improved.
