A significant metabolic illness known as diabetes mellitus is characterized by a lack of insulin or the pancreas failure to produce enough insulin. The blood glucose levels rise as a result of this condition in the human body. Nowadays management of diabetes is very easy by using various technologies such as biosensors. These types of devices are mainly used in the medical field for the advancement in cure and management of disease or disorder accurately.
The main aim of advanced diabetes technology is to treat or control diabetes properly by using continuous glucose monitoring devices (CGM), insulin pens, insulin pumps, smartwatches, and some mobile applications. Above mention devices continuously give information to patients by Bluetooth in the patient’s smartphone or smartwatch and according to data patients have control blood glucose levels and manage diabetes mellitus. While these technologies have demonstrated improvement in health outcomes. For achieving rational control over elevated blood glucose levels, frequent monitoring with invasive blood glucose monitoring techniques is mandatory for diabetic patients. We can easily manage blood glucose levels by using various diabetes technologies. The development of noninvasive glucose biosensor methods will be painless and reduce the complexity of invasive techniques. The main challenge of the biosensor is to recognize biological signals and these signals are transduced into electrical signals after being detected by specified detectors which are made up of semiconductors.
