Wireless heart rate sensing system and method

摘要

Disclosed is a wireless heart rate sensing system which comprises: an oscillator for generating signals of a specific frequency; a power divider for dividing power of the signals generated by the oscillator; a transmit antenna for radiating a first signal output by the power divider to a patient's chest; a receive antenna for receiving a signal, the frequency of which is transited by a motion of the patient's chest and which is reflected and returned; a mixer for combining frequency components of an RF signal received through the receive antenna and a second signal output by the power divider; and a baseband unit for filtering the signal combined by the mixer, converting it into a digital signal, and outputting the digital signal.
