An electrode assembly adapted to be attached to the skin over selected facial muscle groups picks up signals to be analyzed by an anesthesia adequacy monitor that measures the level of awareness of a living animal, typically a human being. The electrode assembly also includes a stimulator that stimulates a facial nerve to determine the level of paralysis, or neuro muscular block, of the facial muscles. Also disclosed is a method of manufacturing the electrode assembly by printing a pattern of electrically conductive material through a silk-screen or an ink type process onto a flexible layer, and then coating the result with a non-conducting adhesive except at points corresponding to sensing points for the desired muscle groups. Finally, a method for using such sensing and stimulating devices is shown in determining and maintaining an appropriate level of patient awareness, muscle paralysis, and analgesia under anesthesia.
