Broadband Blood Glucose Monitoring Using Waveguides from RF to Millimeter Wave Frequencies

This paper presents results from an experimental broadband sensing method using five waveguides covering the frequency range between 7 to 60 GHz in order to study the impact of blood glucose concentration on measured transmission data. The measurement shows a sensitivity of the transmission parameter to glucose concentration, but also to temperature. Based on sensitivity results, a particular frequency band of interest proposed for the development of a potential non invasive glucometer.
