Investigational Outcomes of Normal and Diabetic Human Volunteers using Microwave based Non-invasive Blood Glucometer

Abstract

—Noninvasive estimation of blood glucose using microwave based sensor is one of the most challenging research fields in recent days. These methods are more adaptable to avoid soreness and skin estrangement that occur in traditional invasive blood glucose measurement techniques. This paper suggests the investigational outcomes of a microwave based noninvasive blood glucose meter to check performance of the microwave antenna sensor. Narrowband micro strip antenna with resonating microwave frequency of 1.3 GHz is utilized to measure Blood Glucose Level (BGL) noninvasively. Validity of sensor is assessed by performing medical tests on non diabetic and diabetic human volunteers. Mean Absolute Relative Difference (MARD) and Surveillance Error Grid (SEG) analyses were performed during experimentation to find deviation of estimated BGL from reference BGL which is measured using available invasive technique. Direct assessment of estimated data with reference data provides excellent reliability and repeatability of proposed microwave technique.
