1. An interface system for interfacing a plurality of electrodes with a maternal-fetal monitor, wherein the maternal-fetal monitor has a port configured to operably connect with, receive output from, and display output from at least one of a tocodynamometer, an intrauterine pressure catheter, or a fetal scalp electrode, wherein the interface system comprises:

  • a sensor array dimensioned to attach to a maternal abdomen, wherein the sensor array comprises the plurality of electrodes and wherein each of the plurality of electrodes is configured to detect a physiological signal;

    a first component comprising;

    an electrode interface configured to operably and removably connect with the sensor array and to receive the physiological signals from the plurality of electrodes; and

    a wireless signal transmitter configured to receive the physiological signals from the electrode interface and to wirelessly transmit the received physiological signals to a wireless signal receiver located remote from the first component; and

    a second component comprising;

    the wireless signal receiver configured to receive the physiological signals transmitted by the wireless signal transmitter;

    a signal converter configured to receive the physiological signals from the wireless signal receiver and to process the physiological signals into output data that mimics electrical output from the at least one of the tocodynamometer, the intrauterine pressure catheter, or the fetal scalp electrode; and

    a maternal-fetal monitor port interface configured to operably and removably connect to the port of the maternal-fetal monitor, wherein the maternal-fetal monitor port interface is configured to receive the output data from the signal converter and to communicate to the maternal-fetal monitor the output data when the maternal-fetal monitor port interface is connected to the port of the maternal-fetal monitor.
