ABSTRACT:
A patient monitoring system made of an enclosing cover of electrically insulating and waterproof material encloses two conductive foils separated by an insulating sheet. The upper foil, the one adjacent the patient, is connected to a circuit that applies a carrier frequency signal to the upper foil and uses the lower foil as an electrical shield. An amplifying circuit receives the carrier signal as it is modulated by the movements of a patient adjacent the upper foil and produces an amplified output. The amplified output is demodulated and interpreted by an output circuit that produces signals that monitor selected movements or body conditions of the patient.
