Breath Glucose Monitor Project Supervised by Professor Dr. Ibrahim Abdullah Mardas 1. Project Concept (Why Breath?) Instead of the painful daily pricking to draw blood samples, your device relies on the principle of chemical biomarkers. When blood glucose levels change, the body undergoes alternative metabolic processes that lead to the production of volatile compounds expelled with breath, the most important of which is acetone. 2. Scientific and Technical Principles • Gas Analysis: The device contains a highly sensitive gas sensor (likely from the MQ family) designed to detect acetone molecules at very precise concentrations. • Software Connection: The Arduino (shown in the images) receives the electrical signal from the sensor and converts it, through software equations, into a numerical value representing the approximate blood glucose concentration. • External Design: The images show your use of 3D printing technology to design a comfortable orange casing with a special nozzle for focused exhalation. 3. Medical Significance and Innovation • Painless: Eliminates the need for needle pricks, encouraging patients (especially children) to monitor their blood sugar regularly. • Fast Reading: The device provides an immediate result with a simple blowing motion. • Cost-Effective and Long-Lasting: Compared to disposable blood test strips, it offers a more economical and sustainable alternative. Summary: You have successfully harnessed chemical and electronic engineering to serve medicine by creating a prototype smart device capable of "smelling" diabetes, a global trend aimed at improving patient comfort and quality of life.
