Non-invasive Measurement of Blood Sugar Using Near-Infrared Spectroscopy

Abstract

Named by the World Health Organization as the 7th among the leading causes of death in the world, diabetes mellitus is a disease that must be checked regularly so that the functioning of vital organs in the human body is not affected adversely. Well-established methods for diagnosis and monitoring of the disease may be broadly classified as invasive and minimally or non-invasive methods, with the former class of methods being typically used. However, the minimally invasive or non-invasive methods are undergoing extensive research to make them as reliable as the invasive methods. This paper presents the design and development of a non-invasive blood glucose sensor and discusses its merits and demerits. For hardware design and implementation, the current work employs Microchip’s AVR-IoT board procures results on the Amazon Web Service (AWS) cloud. The proposed system uses the technique of photoplethysmography (PPG) to make blood glucose estimation.
