Abstract

This paper proposes a wireless resonant inductive and capacitive (LC) sensor for glucose sensing. A sensor composed of a capacitor with interdigital electrodes and an inductor for glucose sensing is presented. Resonance frequency and impedance were measured as the sensing parameters. A glucose beverage concentration from 0% to 44% is used, resulting in a resonance frequency change from 1.9217 MHz to 1.8681 MHz, and the impedance of the sensor changes from 170.33 (Formula presented.) to 110.68 (Formula presented.). The relationship of both resonance frequency and impedance to glucose beverage concentration is well presented by a decreasing exponential function. Using an exponential regression, the resonance frequency shows an average regression error of 1.38%. Likewise, the impedance shows an average error of 3.47%. The linear range of the sensor is also analyzed in a glucose concentration range between 0% and 4%. The sensor exhibited a sensitivity of 424.6 kHz and 721.6416 (Formula presented.), respectively, with a linear regression (Formula presented.) of 0.9853 and 0.9553, respectively.
