1. A wireless cardiac monitoring device to measure and transmit cardiac physiological signals of a subject, the device comprising:
a patch configured to be in contact with a skin surface of the subject, comprising:
a plurality of electrodes capable of generating one or more bio-potential signals therefrom; and
at least one wire-free module, embedded in the patch, comprising:
a patch orientation detection module to detect an orientation of the patch on the subject using a plurality of sensors:
a processing module to:
select at least two pair of electrodes from the plurality of electrodes based on the detected orientation of the patch by:
selecting a subset of electrodes from the plurality of electrodes based on the detected orientation, wherein the subset of electrodes are predefined for each detected orientation;
correlating one or more vectors each connecting at least two electrodes of the subset of electrodes with a reference axis, wherein the reference axis is at least one of a horizontal axis and a vertical axis;
determining a confidence score for each of the one or more vectors; and
selecting the at least two pair of electrodes based on the confidence score determined; and
process one or more bio-potential signals corresponding to the at least two pair of electrodes selected, as the physiological signals; and
a transmission module to transmit the physiological signals to an external device for further processing.
