Unobtrusive vital signs monitoring with range-controlled radar

Abstract

Researchers at General Electric have developed a prototype demonstration system that can identify motion and measure breathing and heart rate in periods without general body motions using a range-controlled radar device, similar to motion detectors available in home security systems. With continuous monitoring of the activity and physical vital signs, warning criteria can be used to identify potential crises augmenting existing observational systems without requiring the observed individual to wear or attach any special devices. This has potential applications in correctional facilities to complement observation for inmates at risk of suicide. It has healthcare applications where attaching traditional vital sign monitoring equipment is difficult such as for neonatal or burn patients.
