Remote Sensing of Blood Glucose Level Using an FMCW Radar Sensor

Abstract

A novel sensing approach is presented for glucose level
monitoring where a robust low-power millimeter(mm)-wave
radar system is used to non-invasively differentiate between
blood samples of glucose concentrations in the diabetes range
through detecting minute changes in their dielectric properties.
The processed results have indicated the reliability of using mm-
wave radars in identifying changes of blood glucose levels while
monitoring trends among those variations. Particularly, blood
samples of higher glucose concentrations are correlated with
reflected mm-wave signals of greater energy. The proposed
system could likely be adapted as a portable non-invasive
continuous blood glucose levels monitoring for daily use by
diabetic patients.
