Biological signal sensor on a body surface
First Claim
1. A biomedical sensor, comprising:
- an electrically conductive fiber, comprising;
a fiber core, comprising a plurality of electrically conductive filaments, each filament having a porous outer surface; and
a coating adjacent to the fiber core; and
an ionically conductive medium, comprising an electrolyte, the medium being in electrical communication with the electrically conductive fiber;
wherein the coating is deposited on the porous outer surfaces of the plurality of filaments.

Abstract
An electrically conductive fiber and a coupled biomedical sensor are described. An electrically conductive core of the fiber includes a multiplicity of synthetic conductive filaments and an outer nonconductive fiber layer. The sensor area of the electrically conductive fiber is coated by thin film of silver ink and thin film of silver-silver chloride ink. The electrically conductive fiber'"'"'s porous surface contacts the thin silver ink coating and the silver coating contacts the silver-chloride ink coating. A surface of the biomedical sensor is coated by a thick film of ionically conductive media, containing an electrolyte, in contact with the silver-chloride coating. The electrolyte diffuses into a porous structure of electrically conductive yarn.
