RF Heart Monitor


Heart Monitor:

Researchers at the University of Notre Dame were collecting data in an experiment using remote sensing to find contaminants in food products when they noticed sensitivities to the slightest movement or position changes within the lab room. They speculated that the experimenters' chest motions and even internal organ shape changes, like a heart beating, could influence their measured responses. By redesigning their system they were able to create a remote sensing device that could measure responses due, not to a heart's electrical signals, but to its actual physical movements. This sensor could potentially provide doctors further information to assist in diagnosing arrhythmias, asymmetric heart contractions or cardiomyopathy. It could be used in MRI machines, or used in a neonatal ward. A reduced-performance version could be belt-worn device by pregnant mothers to monitor fetal heartbeat or as a nursery-wide monitor for remotely tracking the respiration and heart rate of sleeping babies. The sensor applies dispersion analysis from another field of research to the field of radio frequency remote sensing, thereby extracting useful information from a phenomenon that has typically been viewed as an impairment. Further development is underway now in this exciting new area of sensing technology.
