Biomedical electrode having skin-equilibrating adhesive at its perimeter and method for using same
First Claim
1. A method of using a biomedical electrode having at least one electrically conductive plate having a perimeter, and having a field of hydrophilic adhesive such that the perimeter of the hydrophilic adhesive exceeds the perimeter of the electrically conductive plate(s), comprising the steps of;
- (a) placing the biomedical electrode on epidermis of a mammalian body; and
(b) permitting water content in the hydrophilic adhesive of the electrode to substantially equilibrate with water content in the epidermis of the mammalian body to alter impedance characteristics of the epidermis.

Abstract
A biomedical electrode is disclosed, having a geometry of a perimeter of hydrophilic adhesive exceeding the perimeter of an area containing electrically conductive plate(s). The geometry unexpectedly causes a reduction in edge effect for dispersive electrodes and cardiac stimulation electrodes due the substantial equilibration of the conductive adhesive with epidermis of a patient the electrode contacts for a period of time sufficient to cause such substantial equilibration.
