  • Patent number: 5458124
    Abstract: A wireless transmitter module for use in a system for monitoring at least one physiological condition of a subject. The transmitter module includes a housing and an electrode patch preferably having three closely spaced electrodes provided on a first surface thereof. The first surface of the patch is coated with a non-allergenic adhesive in regions surrounding the electrodes, whereby the patch is securable to the subject by the adhesive to permit sensing of a physiological signal of the subject by the electrodes. The transmitter module further includes circuitry internal of the housing for detecting a physiological signal sensed by the electrodes and for transmitting a signal corresponding to the physiological signal to a receiving unit.
