Microwave and Impedance Spectroskopy as a Useful Tool for Testing Dielectric Properties of Glucose Solutions
Izabela Anna Osiecka , Tadeusz Pałko
AbstractDiabetes is one of the most common social disease in the world. Due to the patient discomfort associated with sample collection using a commercially available devices, there is a great need to design a more favorable and precise sensor of blood glucose level. Promising techniques are based on the correlation between glucose-induced variations and blood dielectric properties. This report presents two possible methods showing the variations of impedance modulus and relative permittivity values in glucose-sodium chloride (0.9%) and glucose-bovine plasma solutions at different concentrations, ranging from 50 to 500 mg/dl, occurring in human blood. It is worth noticing, that in each sample the dielectric properties depend on the glucose concentration of the sample over the whole studied range, that is 1 kHz–2 MHz for impedance measurements and 100 MHz–5.5 GHz for microwave spectroscopy. The experimental results as well as discussion of the results, are presented in this paper.
