Blood Glucose Monitoring Using Non Invasive Optical Method: Design Limitations and Challenges

This paper intends to discuss the important points related with the design and development of the noninvasive blood glucose monitoring medical device. The advent of a pain free noninvasive technology would improve the patient’s compliance for regular blood glucose monitoring. Subsequently the diabetic patient’s life will improve considerably. The feeble signals produced by the glucose molecules provide the main difficulty in its optical detection. The weak sensitivity, specificity, water molecular spectral overlapping related to the glucose molecules needed to focus for the optimal advancement in this field. Moreover, the skin tissue based scattering, reflection pattern, transmittance plays the major role for the application of the noninvasive based optical techniques. This manuscript critically analyses the difficulties and short comes during the near infrared and mid infrared technique based noninvasive blood glucose monitoring processes. Some vital points are targeted and their optimal solution related issues are identified and discussed here.
