Numerical investigation of a new sensor for blood glucose detection using an improved wave concept iterative process method

Abstract

AbstractGlucose monitoring using a noninvasive, rapid and nondestructive devices is becoming a very challenging task in the present time. This paper presents a modeling and an analysis of an electromagnetic sensor for blood glucose level detection, based on the wave concept iterative process (WCIP) method and operating in the terahertz (THZ) frequency range. The theoretical aspects about the WCIP algorithm, the plasma modeling, and integration into this approach were introduced. The effect of the geometrical parameters variation on the sensor's response was investigated and a comparative study of the obtained results with the high frequency structure simulator (HFSS) simulator is presented in the purpose of the verification. The numerical simulation results using the WCIP method show that the proposed sensor is suitable for the blood glucose monitoring since it was able to detect the lowest and the highest blood concentrations (0 mg/dl and 16 000 mg/dl). The sensing parameters: the quality factor (Q‐factor), figure of merits (FOM), and the sensitivity of the device were calculated in order to prove its efficiency. The Q‐factor varied from 2.26 to 3.06, the sensitivity varied from 0.0501 to 0.0192 (THZ/RIU) and the FOM varied from 0.5758 to 0.3147 RIU−1 for 0 mg/dland 16 000 mg/dl respectively.
