Non-invasive Glucose Monitoring at mm-Wave Frequencies

In this paper, we review our recent experimental studies todevelop a non-invasive blood glucose monitoring system at mm-wave frequencies. A robust 60 GHz radar system is used todifferentiate between hemoglobin samples of disparate glucoseconcentrations through detecting minute changes in theirdielectric properties. A new-developed dielectric assessmentsystem (DAK) is used to characterise the electromagneticproperties of the tested samples and identify the amount ofchange in these parameters at different concentrations of interest.
