Diabetes leads to chronic microvascular complications for the heart, kidney, and eyes due uncontrolled glycemic fluctuations. Self-monitoring blood glucose meters can only provide a snapshot of level are incapable capturing granular fluctuations over 24 h in day. The clinical research has indicated that random lead organ damage. In pursuit better management, Continuous Glucose Monitoring (CGM) is emerging as popular alternative owing its ability detect instantaneous changes levels alert users impending hypo- or hyper-glycemic events. last decade, several CGM devices have been launched market based on different sensing chemistries techniques. More still needed come up with novel bio concepts make low cost highly accurate. Here, we elaborate techniques such electrochemical, optical, reverse iontophoresis, microdialysis, impedance spectroscopy. We emphasize widely used electrochemical CGMs focus sensor design bio-compatibility. also an outlook future technologies, highlighting need innovative materials, possibility integrating Internet Things (IoT) real-time e-health monitoring.
