Abstract
Abstract A flexible, lightweight, inexpensive, and easy to attach sensor mask (10) for placement on a patient (11) for monitoring physiological signals of the patient is disclosed. The sensor mask includes an elongated flexible substrate (12); a plurality of electrodes (14) spaced along the length of the substrate and configured for placement against the patient for sensing the physiological signals; and at least one electrical connector (16) electrically coupled with the electrodes for delivering the physiological signals sensed by the electrodes to a recording/analyzing device. The electrodes are formed of patches of conductive ink that are deposited on the substrate at spaced locations along the length thereof. The electrical connector includes terminals formed of conductive ink deposited on the substrate and is electrically coupled with the electrodes by a plurality of lines of conductive ink deposited on the substrate.
