Wireless heart rate sensing system and method
First Claim
1. A wireless heart rate sensing system comprising:
- 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.
