Sensitivity Difference in Glucose Sensors with Varying the Placement of Two Resonators

This research explores the impact of resonator proximity on sensitivity in sensor design utilizing Rogers 4360G2 as the substrate material with <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$(\varepsilon)$</tex> of 6.15. Noninvasive blood glucose detection is a critical area of research, offering benefits such as improved patient comfort and reduced infection risks. By comparing the sensitivity of near and far resonators using S21 measurements, the study evaluates their ability to detect and measure changes in the system. The results indicate that near resonators exhibit higher sensitivity due to improved energy storage and transmission efficiency. In contrast, far resonators positioned at a greater distance demonstrate reduced sensitivity, posing challenges in detecting subtle variations. This research emphasizes the importance of selecting resonator configurations based on specific application requirements. Leveraging the advantages of near resonators enables the development of highly sensitive and accurate sensing systems, enhancing performance and expanding capabilities across various fields.
