Glucose detection by ۲D fluid-fluid PnC sensor

Here, a ۲D fluid-fluid phononic crystal composed of air holes in a mercury matrix has been considered for the detection of Glucose with concentration up to ۶۰%. The proposed sensor which is a ۹×۱۳ square array provides average Q-factor, highest sensitivity, and highest figure of merit of ۲۰۶۶, ۲۱۴۴ Hz/%, and ۱۰۹ (۱/%), respectively in the frequency range of ۳۹.۷ kHz to ۴۲.۲ kHz The overall size of the proposed sensor is ۴۶۸۰۰ mm۲ and the introduced structure has potential to be used as an efficient sensor for Glucose detection in biomedical applications. The performance of the proposed sensor has been investigated by finite element method in Comsol software and there is a good agreement between the calculated band structures and transmission spectra.
