Abstract

The present work investigates the feasibility of a non invasive blood glucose monitoring system using an antenna placed in a cuff and wrapped around the wrist. The technique is based on the fact that glucose levels affect the dielectric properties of blood. Using a realistic tissue model of a human hand, simulations have been performed with HFSS to obtain the antenna input impedance. The resonant frequency is seen to shift with changes in blood glucose levels. Based on our previous work of tissue characterization, an analytical technique can be developed to relate this frequency shift to the permittivity and conductivity of blood, from which the glucose levels are determined.
