Abstract: Diabetes is a group of diseases that cause blood sugar levels to become too high. It is one most common disease, that can influence other disease. It is important to bring it under control. Monitoring glucose during the past two decades has developed techniques and approaches. In the literature, electrochemical measurements are reported in greater quantities than other methods. This makes them the main subject of this analysis. As a result of their high selectivity for glucose measurement, biosensors remain a main focus of most teams. The principles and types of glucose monitoring sensors are presented in a systematized and classified fashion.. Various design approaches for glucose biosensors are discussed, including needle-type sensors, sensors intended for chronical implantation, and the combination of glucose biosensors with micro dialysis sampling. Continuous glucose monitoring can help to treat better and immediately whenever need.
