Réalisation d'un dispositif de mesure non invasif de la glycémie

Abstract : The main problem of patients with diabetes remains the consequences of the complications resulting from diabetes. More frequent blood glucose control contributes to the balance of diabetes and a significant decrease in its complications. The current devices are less comfortable because of the pain associated with each sting. Some sophisticated blood glucose meters are semi-invasive, and are valid for 14 days. The purpose of my PhD work is to develop a non-invasive blood glucose measurement system based on an electromagnetic method. An original electromagnetic (EM) sensor is proposed, modeled under COMSOL and validated by experimental measurements. This sensor is composed of two Split Ring Resonator (SRR) cells excited by a coplanar line. Our main purpose is to reach sufficient sensitivity to detect different glucose levels with a miniaturized sensor. The sensor is tested on glucose water. Then, it has been optimized and adapted for in-vitro measurements in the blood. In the last part of this study, we identified and quantified the constraints impacting blood glucose measurements. We present the study of two constraints on the measurement of the sensor: Impact of vein dimension and dosimetry. Indeed, the evaluation of these constraints makes it possible to compensate their effects on the measurement for a better precision of the measurement of the glycemia.
