Feasibility of blood oxygen saturation levels using non-contact microwave measurements at 60 GHz

This paper investigates the feasibility of remotely detecting and monitoring blood oxygen saturation levels in humans. The technique relies on the detection of resonances induced by electromagnetic absorption in the presence of oxygen, which are observed at frequencies around 60 GHz (T. A. Ricard, Ph.D. Dissertation. University of South Florida, 2008). In this paper, we develop an electromagnetic model for the cutaneous blood vessels distributed just beneath the skin layer to investigate the feasibility of detecting resonant responses due to the blood oxygen levels.
