Development of a Cost-Effective Portable Diabetes Monitoring Device for Sub-Saharan Africa

Diabetes mellitus, a chronic medical condition characterized by high blood glucose levels, affects more than 24 million individuals in Sub-Saharan Africa. The lack of cost-effective glucose monitoring devices worsens this crisis. Our work introduces GlucoVision, a diabetes monitoring device for this region. GlucoVision utilizes near-infrared (NIR) spectroscopy within a durable wristwatch to non-invasively monitor glucose levels. A K-Nearest Neighbors model demonstrated an average error of $\mathbf{2. 4 5 \%}$, making the model promising for implementation. Cost analysis was performed to calculate a baseline cost of ${\$}$ 13.27. Additionally, a proof-of-concept was created and produced proper results, demonstrating the promise of using the proposed materials.
