Abstract
An electrode assembly for monitoring bioelectric signals includes a first electrode member and a second electrode member disposed around the first electrode member. When the electrode assembly is placed on a body of a person, a bioelectric signal is monitored by measuring the electrical potential between the first and second electrode members with the measurement device. The first and second electrode members may be single electrodes or two or more electrodes connected by conductors. Alternatively, the first and second electrodes can be formed from an array of electrodes by connecting the electrodes in a desired configuration either electrically or by use of a software algorithm.
