  • Flexible sensor pad for non-attached monitoring EKG signals of human subjects
    Patent number: 3954100
    Abstract: A flexible sensor pad upon which a subject sits or lies for acquiring electrocardiogram (EKG) signals from a human subject for continuous monitoring of the subject without attachments to the subject, as during piloting of aircraft or during transportation on a stretcher, to enable activation of an alarm upon certain conditions. The sensor pad includes a flexible waterproof backing sheet of textile fabric, a pair of flexible pick-up panels of non-corrosive, highly conductive fabric such as cloth formed of threads having metallic strands, and a thin cover cloth which is permeable to peripheral perspiration of the subject to effect transmission of the EKG signals to the pick-up panels by the perspiration.
