RF assisted non invasive method for blood glucose monitoring - a feasiblity study

An RF assisted biosensor for real time blood glucose monitoring in humans/animals is demonstrated utilizing the resonance characteristics of a Complimentary Stepped Impedance Resonator (CSIR). The resonator is excited using the reactive near field of an open circuit terminated microstrip transmission line. The proposed sensor is found to show linear variation from 0 to 3000mg/dl of glucose concentration in water. Experiments are carried out using animal tissues to confirm the feasibility as an implantable device.
