Data Processing and Analysis of Glucose Concentration According to the Immittance Meter

Abstract

This article proposes a method for measuring glucose concentration as a possible promising way to create a non-invasive glucometer. The dependence of the complex resistance of a solution of sodium chloride with different concentrations of glucose is investigated. In fist the glucose concentrations were calculated in saline to carry out these measurements. Further we prepared solutions (test samples) with a content of 3, 5, and 10 mmol per liter. We also created a board layout for measurements, that allowed us to vary solutions with different glucose concentrations. Using an immittance meter, we measured the complex resistance as a function of frequency in the range from 25 Hz to 1 MHz. At a medium frequency, we observed a resonance. We also found that at a frequency of 2 kHz there is a clear dependence of the complex resistance on the increase in glucose in solution. The obtained measurement data is of great interest for non-contact monitoring of glucose concentration in biological fluids.
