Abstract
Abstract A biomedical electrode for an electrocardiograph or similar device is provided. The biomedical electrode includes a disposable electrode having an electrically conductive gel layer and a smooth layer film. The disposable electrode interfaces with a reusable leadwire connector having the relatively expensive metallic conductive material. The reusable leadwire adapter includes a vinyl top layer which attaches to the smooth layer film of the disposable electrode through surface attraction. The reusable leadwire adapter may include a suction cup which attaches to the disposable electrode through a partial vacuum. The reusable leadwire also includes a stud member which snaps into a standard leadwire connector.
