Advances in a Microwave Sensor-Type Interdigital Capacitor with a Hexagonal Complementary Split-Ring Resonator for Glucose Level Measurement

This study involved the creation and assessment of a microwave sensor to measure glucose levels in aqueous solutions without invasiveness. The design utilized planar interdigital capacitor (IDC) loaded with hexagonal complementary split-ring resonator (HCSRR). HCSRR was chosen for its ability generate highly intense electric field that is capable detecting variations dielectric characteristics specimen. A chamber tube used fill at sensor’s sensitive area, changes device’s resonance frequency (Fr) reflection coefficient (S11) were levels. Fitting formulas developed analyze data, laboratory tests showed could accurately within range 0–150 mg/dL. At concentration 37.5 mg/dL, sensitivity based on S11 Fr reached maximum values 10.023 dB per mg/dL 1.73 MHz respectively. implies put forward has possibility being medical settings monitoring
