Resumen

This project focuses on the characterization of an electromagnetic sensor made from a substrate-integrated waveguide resonator in the presence of different solutions with different glucose concentrations. The objective is to determine if it is a viable and non-invasive technique for implementing it in devices for detection of blood glucose levels. Different frequency sweeps were carried out to know the response and the change in the electrical permittivity of the sensor. Different comparisons were made between the resonant frequency and the concentration and between the signal attenuation and the concentration, to determine that there is an increase in the amplitude of the signal with the increase in the glucose concentration of the sample. Additional analysis indicates that there is a shift of the frequency band to the left with lower glucose concentrations. The study concluded that it is evident that there is a relationship between the increase in glucose concentration and the response of the sensor, but more research and testing is necessary to establish a rule that describes the behavior.
