Description: The heart to pump blood out of the body caused by vibrations synchronized with the heartbeat, tremor signal generating body, its own rules and heart-related, can be detected by sensitive spinal axis force sensor body fluttering signal is weak and susceptible to interference, for this feature designed the sensor circuit and signal processing circuit, the detection method described. first original body fluttering signal obtained pre-treated to remove noise and then apply the modulus maxima algorithm for each cardiac cycle peak point, and finally determined the heart rate. when collecting body fluttering signal all the way to a single-channel synchronous acquisition accuracy of ECG as a reference to uate the measurement results show that, to obtain good results heart rate measurement method body shock signal.
