GLASS: Glucose Level Measuring via Breathe Acetone Sensing through Laser Spectroscopy
By Akul, Rohith
Current continuous glucose monitoring systems are prohibitively expensive, leaving many diabetics without reliable glucose tracking. This study explores a non-invasive alternative by measuring breath acetone, an established biomarker for blood glucose, using near-UV laser spectroscopy. We developed a custom experimental setup involving a multipass gas chamber and a 275 nm UV diode. Preliminary results confirm the capability to detect acetone and the effectiveness of humidity control using a breathing tube with Drierite. Limitations in diode power and data scope restricted comprehensive analysis; however, the findings demonstrate the promise of this technique as an affordable, non-invasive glucose monitoring method.
