An Overview of Current and Emerging Biomaterials Technology for Continuous Glucose Monitoring (CGM) Devices -- Current state and future perspectives of the leading technologies

Abstract: In the world today, diabetic complications are a major factor in the disease's high mortality rate. Diabetes mellitus has been a major source of concern for decades due to its global prevalence and the resulting rising costs to individuals, governments, and healthcare systems on both a social and economic level. The complex interplay between nutrition, exercise, stress, medicine, sickness, and hormonal changes makes controlling diabetes difficult. Even though there is currently no cure for diabetes, the condition may be managed with careful attention to blood glucose levels and the use of appropriate medications. Blood sugar levels should be monitored on a regular basis, which requires a glucometer and a fingertip and is becoming the standard in diabetes control technologies. For the convenience of diabetic patients, the use of a CGM device for monitoring glucose levels has become the preferred method. For diabetes therapy at the point of care, replacing finger-prick glucometers can be done anywhere they are currently on the market. As a result, it has sparked a lot of interest in a variety of glucose sensing mechanisms, particularly non-invasive or marginally glucose sensing mechanisms that focus on subcutaneously implantable electrochemical sugar sensors that work more reliably and last longer.
