Microwave MTM-based sensor for blood glucose concentration measurement: Sensitivity analysis by means of numerical simulations

摘要

In this work two different models of dielectric properties of blood glucose solutions are used to evaluate metamaterial sensor sensitivity by means of numerical simulations. Model A is adopted from professional literature and the model B was created by our group using information about dielectric properties of blood plasma-glucose solutions, recently published dielectric properties of red blood cell cytoplasm-glucose solutions and an electromagnetic mixing formula. It can be concluded that the sensor shows smaller sensitivity for the model B than for the model A. Furthermore it shows due to non-linear dependency of dielectric properties on glucose concentration predicted by model B a lower sensitivity for high glucose concentrations.
