Detection of varying glucose concentrations in water solutions using a prototype biomedical device for millimeter-wave non-invasive glucose sensing

摘要

This paper presents an overview of a novel non-invasive device for detection of glucose variations in water solutions in the range 56 – 61 GHz. The system is in lab prototype stage and with the use of a PNA, glucose variations can be correlated to transmission measurements through the solutions. Experiments indicated that higher power levels at the receiving side account for higher glucose concentrations. Finally, a theoretical analysis gives the minimum glucose variation that can be accurately resolved by the device, based solely on the quality of the received signal as seen by the measuring instrument.
