Description
Summary:In recent years researchers have explored non-invasive techniques for glucose testing such as near infrared spectroscopy, light scattering, photoacoustic spectroscopy, and electrical impedance measurements, without achieving the accuracy of the traditional invasive method. In this paper, measurements in the 1-13 MHz band show that glucose directly affects the impedance parameters of solutions and the effect is more evident in the phase angle; therefore, these impedance phase measurements can be employed to predict the concentration of glucose in vitro, obtaining a smaller error of prediction than previous techniques.
