Problem Statement & Value Proposition

Problem Statement

The current standard for blood glucose monitoring relies on invasive techniques that can deter frequent use and limit participant comfort in research settings. Despite advances in biosensor technology, there remains a lack of accessible, non-invasive devices that can accurately measure glucose concentrations through alternative indicators such as breath. This project seeks to address this gap by developing a breath-based glucose sensing system designed specifically for research use. The system will serve as a supplemental data-collection tool that can be used to aid researchers in validating correlations between exhaled biomarkers and blood glucose levels.

Value Proposition

Our device offers researchers a practical bridge between laboratory glucose studies and non-invasive measuring methods. Our device enables painless, real-time physiological data collection using compact, modular hardware and integrated digital data-logging. This approach lowers research barriers, improves participant comfort, and helps validate emerging methods for non-invasive glucose detection.
