Unitary multi-electrode biopotential signal sensor and method for making same

摘要

A unitary, multi-electrode biopotential signal sensor (10) is formed of injection molded plastic. A plurality of electrode areas (24) containing spikes (32) are defined in a base member (22) of the sensor. The remaining areas (28) of the base member (22) are formed to have a greater flexibility than the electrode areas (24), by being thinner or perforated. The spikes (32) and electrode areas (24) of the base member (22) are coated with a conductor layer (36) to form the electrodes. Conductors (40) on the base member lead to connectors (42) to provide biopotential signals from the electrodes. <IMAGE>
