ABSTRACT:
A novel biomedical electrode comprising 1) a non-conductive backing layer with instructions printed on one surface, 2) an ink layer having either a) an ink comprising silver and silver salt, or b) a blend of inks including a first ink comprising silver and silver salt and a second ink comprising an inert carbon based material printed in a pattern onto the second surface of the non-conductive backing layer, 3) a conductive-adhesive electrolyte layer coated directly onto the inked surface of the non-conductive backing layer, and 4) a protective release liner which covers the conductive adhesive layer. Certain preferred embodiments correspond to situation wherein the body parts being monitored display diverse impedances. In those embodiments, parameters such as ink blend, ink amount (i.e., ink thickness and ink pattern) are varied in order to vary the impedance of a given electrode. These impedance distinct electrodes allow for the construction of a set of electrodes in which the varying impedances of the different electrodes compensate for the varying impedances of the different body parts. The construction of the electrode set also allows for a single line manufacturing process.
