CONCENTRIC ELECTRODES FOR DETECTING BIOELECTRIC SIGNALS

摘要

2105400 9217112 PCTABS00016 The present invention is directed to an electrode (1) for use in measuring low level signals amidst competing noise signals. The electrode (1) includes an electrically non-conductive substrate (2) having a closed loop (3) of electrical conductive and adhesive material carried by the substrate (2) which defines therein an open area on the substrate (2). A first electrically conductive terminal (4) is embedded within the closed loop (3) of electrically conductive and adhesive material. Within the open area is an inner mass (6) of electrically conductive and adhesive material. The inner mass (6) of electrically conductive and adhesive material is spaced from the closed loop (3). The electrode (1) also includes a second electrically conductive terminal (5) which is embedded with the inner mass (6) of electrically conductive and adhesive material. The electrode (1) includes a first contract device (3) for making electrical contact with the first terminal (4) and a second contact device (7) for making electrical contact with the second terminal (5).
