Remote monitoring of vital signs (VS) is an emerging technology with a vast number of possible uses from hospital care to the automotive industry and assisting living environments. Radio-frequency (RF) sensing enables the remote and unobtrusive measurement of VS without the need to wear any special device or clothing and under any lighting conditions. In the present paper, the feasibility of remote respiration, heart rate (HR) and stress detection monitoring was investigated. A continuous wave reflectometer based on COTS components and laboratory equipment was designed and prototyped in order to investigate and demonstrate the principles of remote VS sensing: 75-110 GHz (remote respiration, HR, stress) and 325-500 GHz (stress).
