SYSTEMS AND METHODS FOR MONITORING RESPIRATION AND MOTION

Systems and methods for remotely sensing movement of a mammalian subject utilize a radio frequency (RF) transmitter configured to impinge a RF signal on tissue of a mammalian subject, a RF receiver configured to receive a reflected RF signal, a processor configured to separately identify presence of respiratory and non-respiratory motion of the mammalian subject, and a memory configured to store processes signal values generated by or derived from the processor, wherein the processor is configured to compare one or more processed signals against one or more stored processed signal values, and detect a health state or health condition of the mammalian subject. Sleep apnea and respiratory events may be detected. In one embodiment, motion of a human infant may be mapped over time, and motion trends may be used to assess proper development of the infant.
