Microwave Based Biosensor for Blood Glucose Monitoring

The proposed study investigates the feasibility of a microwave based sensor - the Split Ring Resonator (SRR) and its complementary structure (CSRR), as a non/minimally invasive blood glucose monitoring system. The technique is based on observing the change in resonance frequency of the resonators which is a function of their geometry and the dielectric constant of the surrounding medium. Here the change in dielectric constant of blood due to variation of glucose level is subject to study. Analysis has been carried out using the resonator in simulation and confirmed through experimental studies. A linear response is obtained from the sensor with variation of glucose level up to a certain level, which promises future of CSRR as an efficient biosensor.
