Microwave Non-Invasive Blood Glucose Monitor: Progress and Real-World Challenges to Commercialisation Pathway

This workshop presents the Non-Invasive Blood Glucose Monitor (NIBGM) project, which investigates RF and microwave resonant sensing for continuous, non-invasive blood glucose monitoring. From a microwave engineer’s perspective, the talk highlights challenges encountered when progressing from laboratory prototypes to clinical trials, including sensor calibration, physical interference (pressure, placement, and tissue variability), and specificity. Experiences of working with industrial partners and navigating translation and follow-on funding opportunities are discussed. Ongoing RF and microwave hardware development is presented alongside a critical perspective on the potential role of AI-based methods for future calibration, drift compensation, and interference correction.
