Abstract:

Global demand for accurate non-invasive glucose monitoring remains unmet, because most wearable technologies fail to deliver the required clinical performance. CEA-Leti offers a device breakthrough with mid-infrared quantum cascade laser (QCL) photoacoustic technology on silicon. Operating in the mid-IR spectrum, it provides the specificity and sensitivity needed for real-time biomarker tracking without invasive sampling.

Engineered for large-scale semiconductor manufacturing, the system ensures cost-effectiveness and significant scalability. Its retunable architecture allows a single hardware design to detect diverse biomarkers across medical and industrial sectors. The institute aims to accelerate time-to-market through this multilateral industrial program.

This initiative reshapes non-invasive monitoring, enabling next-generation smart wearables like smartwatches for sport, wellness, and health. By translating this breakthrough into low-cost devices, CEA-Leti opens pathways for detecting crucial biomarkers and molecules beyond glucose, addressing global consumer demand, while overcoming previous technological limitations.
