Non-invasive Estimation of Blood Glucose Level in Visible-NIR Spectrum: System and Software Design

We have designed and developed a non-invasive blood glucose level monitoring system. The electromagnetic spectrum of both visible and infrared region has been used for the study of absorption, refraction, and reflection of bio-molecules. In this article, we have shown the system model and data acquisition platform based on Android user interface. The system model includes a proposed multi-sensor signal processing sub-system, an embedded platform, and a Bluetooth wireless transmission subsystem. The proposed system has been investigated on normal and diabetic patients. The stability of the device is tested using a one-way ANOVA test. The result of the hypothesis test has shown in favour of acceptance of the datasets provided by the device.
