Invasive and Non-Invasive Glucose Monitoring Systems: A Review and Comparative Study

As the incidence of diabetes has expanded worldwide in recent years, an increasing number of patients are experiencing pain and infections because to the invasive nature of the majority of commercial glucose measurement systems. The availability of reliable, low-cost, painless, noninvasive technology will promote patient compliance to routine blood glucose monitoring. The life of the diabetic patient will thereafter significantly improve. Several technologies have been proposed and developed by scientists and researchers in an attempt to enhance their effectiveness. This study reviewed both invasive and non-invasive glucose monitoring techniques, with an emphasis on optical methods. Non-invasive glucose monitoring devices that are painless, sensitive, and transportable are being suggested and developed to better understand glucose levels.
