With the growing global prevalence of diabetes, there is an urgent need for non-invasive, user-friendly, and reliable methods of blood glucose monitoring. Traditional techniques, such as finger-prick tests, are often painful, inconvenient, and unsuitable for frequent daily use, leading to poor patient compliance and suboptimal glucose management. Addressing this challenge, we propose a mobile-based, non-invasive glucose monitoring system that utilizes breath analysis as an alternative to conventional methods. The solution is centered on detecting acetone levels in a patient’s breathe an established biomarker correlated with blood glucose concentrations using the MICS-5524 gas sensor. The system integrates this sensor with a smartphone application to provide real-time glucose estimations, health alerts, and continuous tracking. This innovative approach not only reduces physical discomfort but also enhances user engagement and accessibility in diabetes management. By offering a practical, non-invasive, and portable solution, the proposed system has the potential to transform how individuals monitor and manage their blood sugar levels, ultimately improving health outcomes and quality of life for diabetic patients.
