Systems and methods for providing overcharge protection in capacitive coupled biomedical electrodes

An alternating electric field responsive composite providing capacitive coupling through the composite for biomedical applications, said composite comprising a binder material, a polar material that is substantially dispersed within said binder material, and electrically conductive particles within the binder material, wherein said binder material and said polar material exhibit mutual molecular compatibility, and wherein said electrically conductive particles remain substantially isolated from one another within the binder material.

A biomedical composite including discrete paths of electrical conductivity through the biomedical composite, wherein the paths of electrical conductivity are formed of carbon materials that extend in a direction through the biomedical composite, yet do not provide electrical conductivity in directions transverse to the direction through the biomedical composite such that said biomedical composite may be used in a biomedical electrode exhibiting anisotropic conductive properties.

A method of providing a overcharge protection in an alternating electric field responsive composite, said method comprising the steps of providing a binder material, adding a polar material to the binder material such that the polar material becomes substantially dispersed within said binder material and the binder material and the polar material exhibit mutual molecular compatibility, and adding electrically conductive particles to the binder material such that the electrically conductive particles remain substantially isolated from one another within the binder material unless and until an overcharge is applied that causes the electrically conductive particles to undergo electrophoresis within the composite and form conductive paths through the composite.
