1. A fabric cover for an infant incubator or warmer, comprising:
a plurality of electrodes spaced apart from one another within a measurement area of a surface of the fabric cover adapted to have direct contact with a patient, the plurality of electrodes including a topmost electrode extending across an entire width of the measurement area, a bottommost electrode extending across the entire width of the measurement area, and a set of electrodes arranged between the topmost electrode and bottommost electrode, in a direction perpendicular to the width, within the measurement area, where the topmost electrode and the bottommost electrode are dedicated, driven electrodes and each electrode of the set of electrodes is a measurement electrode;
an integrated electronic layer electrically coupled to the at least one electrical connector and adapted to perform measurements on electrical signals received from the plurality of sensors;
wherein the integrated electronic layer includes a dynamic switching circuit including an input switch matrix and an output switch matrix adapted to switch which electrode of the topmost electrode and the bottommost electrode is driven to output a driven common mode output signal and which signals received from the set of electrodes are used to determine an electrocardiogram signal of the patient based on which electrode is in direct contact with the skin of the patient, the input matrix separated from the output matrix by an amplifier; and
wherein the dynamic switching is adapted to switch based on a position of the patient on the fabric cover.
