Comparative Study and Analysis of Non-Enzymatic Glucose (Neg) Sensors, Modelling and Simulation of a High-Performance Neg Sensor Using Finite Element Analysis

This research reports the design and simulation of a high performance non-enzymatic glucose (NEG) sensor. The function of high-performance sensor is simulated to observe its sensitivity in detecting the glucose level in blood. Non-Enzymatic Glucose sensor having a non-organic electrode namely ferrocyanide is modelled using Finite Element Method. The glucose concentration is measured by calculating the current generated when electrode reaction occurs in the strip. Sensitivity is observed for different glucose concentrations. The sensor could detect glucose concentrations at values as low as 0.1mmol/L by generating a corresponding current of 0.5 A/m2. The design has been compared with experimental results obtained from other research studies. Results indicate that ferrocyanide shows promising outcomes both in terms of sensitivity and selectivity in comparison to other electrode materials which are currently in use.
