Development of Smart Insulin Device for Non Invasive Blood Glucose Level Monitoring

Diabetes is one of the life threatening diseases in theworld. Nowadays, diabetes patients are increasing due toimproper monitoring of blood glucose level. The diabetes infectedpatients have to check the amount of glucose level present in thebody using invasive method. By using this method, they have totake a drop of blood from the body and check the amount ofglucose level, by which they can inject the required amount ofinsulin into the body. To overcome the difficulties caused byinvasive method, in this prototype we are using non-invasivemethodology. The main objective of this work is to design aportable non-invasive blood glucose level monitoring device usingnear infrared sensors. The device includes Infrared LED,Photodiode and ATMEGA328 Microcontroller. Besides beingable to detect glucose concentration in blood, the device alsodisplays the required insulin dose based on glucose levelcorresponding to the Body Mass Index (BMI) of the user.
