Remote Sensing of Blood Glucose Level Using an FMCW Radar Sensor

A novel sensing approach is presented for glucose levelmonitoring where a robust low-power millimeter(mm)-waveradar system is used to non-invasively differentiate betweenblood samples of glucose concentrations in the diabetes rangethrough 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 whilemonitoring trends among those variations. Particularly, bloodsamples of higher glucose concentrations are correlated withreflected mm-wave signals of greater energy. The proposedsystem could likely be adapted as a portable non-invasivecontinuous blood glucose levels monitoring for daily use bydiabetic patients
