Motion Detection for Physiological Applications: 6,480,111


A method and system for physiological monitoring using a microprocessor-enhanced magnetic field sensor to measure the mechanical effects of body motion is described. The measurements may be used for a variety of applications, such as detection of respiration, cardiac rhythms, and blood pressure. The source or detector may be made sufficiently small so as to be implantable. The system is sufficiently sensitive to provide output data for very small movements.
