Optical sensors for continuous glucose monitoring

Abstract For decades, diabetes mellitus has been of wide concern with its high global prevalence, resulting in increasing social and financial burdens for individuals, clinical systems governments. Continuous glucose monitoring (CGM) become a popular alternative to the portable finger-prick glucometers available market convenience diabetic patients. Hence, it attracted much interest various sensing technologies develop novel sensors better performance longer lifetime, especially non-invasive or minimally invasive sensing. Effort also put into finding biocompatible materials implantable applications achieve effective vivo CGM. Here, we review state-of-the-art researches field The currently commercially CGM have analyzed summary is provided potential types recently researched monitors. Furthermore, challenges advances towards introduced discussed, hydrogel aimed at minimizing adverse impact from foreign-body response. In addition, large variety promising glucose-sensing under research reviewed, traditional electrochemical-based optical other electrical sensors. recent development achievement reviewed are together analysis terms statistical data newly published patents related field. Thus, direction future work this could be concluded.
