Diabetes has been a prevalent problem of modern society for quite a while, the remedies to the problems are present but either they are too expensive or stressful to be implemented by all. This project focuses on the technologies behind the old methods and initiatives taken to develop new and improved methods of testing while reducing the cost and margin of error.

Monitoring of glucose had been done conventionally by the means of a blood sample on a test strip, due to the advancements in the technology over the years, more minimally inva-sive and noninvasive methods have been tried and tested. They provide reliable enough data to monitor glucose level without the need of pricking the finger continuously. In this project, the possibility of a cheaper and more accurate glucometer by using the compo-nents easily available on the market is proposed, which will be compared to the ones al-ready available. CGM (Continuous Glucose Monitoring) has been at the forefront of diabe-tes solutions because it provides flexibility and portability which has never been offered before and monitoring which is done every minute so that even the smallest fluctuations can be known beforehand. With the help of the system already in place for CGMs, a new and revolutionary method known as the closed-loop system is introduced. This method is implemented by integrating an insulin pump and the CGM, making the insulin injection au-tomatic.

Analyzing the results of the proposed system, it is possible to make a cheaper and more accurate glucometer than those already available on the market. However, the future lies in the systems that do not need blood or human intervention such as minimally and noninva-sive methods of glucose testing, therefore artificial pancreas is the next step of evolution for the diabetes community
