Socioeconomic Impact Figure 3. Diabetes management through glucose monitoring. with closed-loop system (see Figure 3).5 The serum glucose monitoring would allow the accurate glucose monitoring for appropriate control mechanism.7 The integrated IoMT framework with continuous serum glucose measurement and insulin pump is helpful to provide proper insulin delivery with closed-loop automated insulin control. Glucose Measurement Consumer Products Various types of noninvasive Glucometers are available in the market for invasive, noninvasive, and minimal invasive types. The CGM approaches are either semi-invasive or noninvasive in nature. The implantable devices are minimal (or semi) invasive type based on biosensing glucose principal. Smart contact lenses, sweat patches, and Glucowatch are wearable types of sensors based on spectroscopic in nature. The wearable devices would provide frequent glucose measurement with state-of-art solutions. The comparative study of few selected noninvasive glucose measurement consumer products have been reported in Table 2. Glucose Sensing Approaches and Its Control The development of glucose-insulin control model includes various parameters such as glucose absorption rate, renal excretion rate, glucose consumption, net hepatic balance etc. The glucose control model has been designed to balance the glycemic profile of diabetic person.5 There are few mathematical models were developed for insulin drug delivery for type-2 diabetes patients. One of most popular FDA approved simulator " Uva/Pendova " was used with virtual patients database of type-1 diabetes.8 The Table 2.
