Anisotropic adhesive multiple electrode system, and method of use
First Claim
1. A bioelectric interface comprising an adhesive sheet in functional combination with at least two spacially separated electrodes, which adhesive sheet simultaneously presents with essentially anisotropic specific impedance properties and essentially isotropic mechanical pliability and adhesion properties, said electrodes being affixed to said adhesive sheet in a manner such that their relative positions with respect to one another are essentially fixed, and such that the specific impedance from each said electrode directly through said adhesive sheet, is less than that between any said electrodes through said adhesive sheet, said electrical anisotropic specific impedance properties of said adhesive sheet being the result of a slit or slits therein, which slit or slits is/are positioned between electrodes.

Abstract
A bioelectric interface is disclosed which provides a plurality of electrodes affixed to an adhesive sheet which demonstrates electrode isolating anisotropic electrical specific impedance properties simultaneous with isotropic pliability and adhesion mechanical properties. The bioelectric interface can be configured to provide electrodes positioned for use in, for instance, twelve lead (ECG) systems as well as in any other configuration. Groups of electrodes can be present in certain locational regions to allow single sized systems to fit to patients with various sized bodies. The electrodes can be of various physical shapes to allow not only direct signal measurement, but also to allow monitoring of high frequency content of signals and to allow enhanced resolution of a region from which measured signals originate. When present, extra electrodes in a group thereof can be used for purposes, such as cardiac pacing. In addition, the present invention bioelectric interface need not be removed to allow cardio-pulmonary-resuscitation or defibrillation to be performed, and it serves to preserve the relative spacial integrity of the positioning of the electrodes present during use.
