Sensitivity Comparison Between Reflection and Transmission Coefficient by Free Space Method for Non-Invasive Glucose Monitoring Sensor

Abstract

This paper presents the comparison of sensitivity between the reflection and transmission coefficient by free space method for non-invasive blood glucose monitoring. In this study, aqueous glucose solutions with concentration values of 0, 1, 2, 3, and 4 w/v\% have been tested. The calculation is done using formulas based on a three-layer model. The calculation results are then compared with the simulation results. Both calculation and simulation show almost the same results. The measurement of reflection and transmission coefficient is also implemented by using horn antenna. The results show that transmission coefficient is more sensitive with respect to the change of glucose concentration.
