摘要：
A biomedical electrode is disclosed that includes at least first and second electrical nodes for connection to medical equipment. The biomedical electrode includes a first electrical node including a disc of conductive material having a diameter d1 and a second electrical node including a ring of conductive material. The ring is concentric with the disc and- has a diameter d2 that is larger than d1 and having a ring thickness t2 such that (4 = d1 / t2 = 6). It is further disclosed a biomedical electrode providing at least first, second, third and fourth electrical nodes for connection to medical equipment, said biomedical electrode comprising said first electrical node including a disc of conductive material having a diameter d1； said second electrical node including a first ring of conductive material, said first ring being concentric with the disc and having a radius a that is larger than d1/2； and said third electrical node including a second ring of conductive material, said second ring also being concentric with the disc and having a radius ß that is larger than d2/2； said fourth electrical node including a third ring of conductive material, said third ring also being concentric with the disc and having a radius of thirty millimeters that is larger than d3/2, such that (3 a ß)2 is less than about 0.225 cm4.
