Non-Invasive Monitoring of Blood Parameters Using Biosensors For Medical Applications

The proposed paper presents a sensor design with four cells of complementary split ring resonator (CSRR) on top of FR-4 dielectric substrate and microstrip on the substrate's bottom side through which sensor elements are excited. The frequency shifting / difference value of transmission coefficient for glucose and cholesterol is minimum at 0 GHz and 0.0016 GHz, it is maximum at 1.5706 GHz and 0.033 GHz also the frequency shifting / difference value of Voltage Standing Wave Ratio (VSWR) for glucose and cholesterol is minimum at 0.0009 GHz and 0 GHz, it is maximum at 0.4541 GHz and 0.007 GHz. From these values it concludes that sensor gives more accurate and precise result than triple-pole complementary split ring resonator. The proposed sensor operates in the frequency range of 1–6 GHz and it is designed on Computer Simulation Technology (CST). This CSRR- based sensor can be used to monitor the blood parameters such as blood glucose level, cholesterol level by detecting variations in dielectric properties of blood.
