摘要：
A heart pulse monitor includes a permanent magnet including a mounting structure for securing the permanent magnet in displaceable contact with a blood vessel of a wearer. The permanent magnet has a thickness defining an axial direction that the permanent magnet is displaceable when blood flows. A fluxgate sensor system is positioned a distance in the axial direction from the permanent magnet to sense an axial magnetic field therefrom. The permanent magnet displaces in the axial direction upon a heart pulse of the wearer resulting in a change in the axial magnetic field which is sensed by the fluxgate sensor system through a change in an induced AC output signal on the sense coil. A processor is coupled to receive information from the induced AC output signal. The processor implements calibration data which converts information from the induced AC output signal into a heart pulse measurement for the wearer.
