Description
Summary:In this study, a portable prototype of a planar microwave sensor is proposed for intermittent glucose level monitoring. The sensor element basically consists of four distinct hexagonal-shaped complementary split ring resonators (CSRRs) configured in the honey-cell pattern and fabricated on an FR4 dielectric substrate. The CSRRs are coupled via microstrip transmission line to a radar system operating in the ISM band 2.4-2.5 GHz. The integrated sensor shows a remarkable detection sensitivity for the diabetes-spectrum glucose levels dissolved in the blood mimicking aqueous solutions. This is demonstrated by the raw data collected by the radar receiving channel, which shows a clear trend following the variations in glucose levels.
