Multiband Complementary Split Ring Resonators For Non-Invasive Glucose Monitoring

This paper presents a comparative study of transmission-based microwave sensor for rapid, precise, non-invasive blood glucose monitoring as an effective method for diabetes management and continuous monitoring. A comparative study between two shapes of Complementary Split Ring Resonator (CSRR) is conducted to realize a highly sensitive senor with low profile and high-quality factor. The proposed sensor design is made on a thin sheet of Rogers RT/Duroid 6002 dielectric substrate and includes three concentric CSRRs. To examine the sensitivity of the sensor, two sampling techniques for glucose solutions are used with concentrations from 0 mg/dL to 400 mg/dL. The established sensor exhibits a remarkable sensitivity of 0.067 degrees/(mg/dL) and 0.42 MHz/(mg/dL) to blood glucose levels and superior detection capabilities.
