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

Diabetes is one of the life threatening diseases in the world. Nowadays, diabetes patients are increasing due to improper monitoring of blood glucose level. The diabetes infected patients have to check the amount of glucose level present in the body using invasive method. By using this method, they have to take a drop of blood from the body and check the amount of glucose level, by which they can inject the required amount of insulin into the body. To overcome the difficulties caused by invasive method, in this prototype we are using non-invasive methodology. The main objective of this work is to design a portable non-invasive blood glucose level monitoring device using near infrared sensors. The device includes Infrared LED, Photodiode and ATMEGA328 Microcontroller. Besides being able to detect glucose concentration in blood, the device also displays the required insulin dose based on glucose level corresponding to the Body Mass Index (BMI) of the user.
