Electrical conductor for biomedical electrodes and biomedical electrodes prepared therefrom

摘要

PCT No. PCT/US96/05938 Sec. 371 Date Apr. 26, 1996 Sec. 102(e) Date Apr. 26, 1996 PCT Filed Apr. 29, 1996 PCT Pub. No. WO97/41568 PCT Pub. Date Nov. 6, 1997An electrical conductor and a biomedical electrode using the electrical conductor are disclosed. The electrical conductor has a flexible, non-conductive film and two different carbon-containing coatings on a major surface of the film. The electrical conductor coatings are a low porous carbon-containing coating and a high porous carbon-containing coating. The low porous carbon-containing coating contacts the film and the high porous carbon-containing coating contacts the low porous carbon-containing coating. A tab/pad style of biomedical electrode using the electrical conductor has a field of ionically conductive media containing electrolyte contacting the high porous carbon-containing coating. The electrolyte diffuses into the high porous carbon-containing coating for electrochemical advantages.
