Substrate materials for epidermal use on subject, apparatus comprising same, and/or methods of manufacture thereof

Abstract

One aspect of the present invention is concerned with a substrate material for epidermal use on a subject, e.g. human subject. The substrate material has a matrix ingredient of polyvinyl alcohol (PVA), a plasticizing agent of glycerol (gly), and a conductive material of graphite, carbon black, and water. Another aspect of the present invention is concerned with an electronic apparatus having such a substrate material and an electronic device for recording electrical signals received through the substrate material, wherein the electrical signals are indicative of one or more physiological or physical parameters of a subject on which the electronic apparatus is applied or one or more parameters of the surroundings to the subject. Yet a further aspect of the present invention is concerned with a method of making a substrate material.
