Dual Ring Complementary Split Ring Resonator (DR-CSRR) Sensor For Non-invasive Glucose Sensing Application.

摘要

Non-invasive way is a certain diagnostic method that does not involve any kind of painful activity such as finger pricking, removal of body tissue etc. With advancement of recent technology and research, diagnostic system is shifting towards new non-invasive ways to detect various disease and malfunction in human body. But for real world application results of non-invasive way must match to that of invasive one. This paper focuses on detection of small changes in low level concentration of aqueous glucose solution using highly sensitive CSRR (Complementary Split Ring Resonator) loaded micro-strip patch antenna. In this study, vivid resonant frequency shift has been observed with small changes in glucose concentration in aqueous glucose solution. This sensor can detect glucose concentration level with sensitivity of 1.38 MHz/(mg/ml). Hopefully, proposed sensor can be effectively experimented with human saliva for detecting blood glucose level of targeted person in future.
