Needleless Glucose Monitor

This project introduces a wearable, needleless glucose monitor that uses radar and metasurface technology to detect glucose levels beneath the skin without pain or consumables. A compact millimetre-wave radar module enhanced by a programmable metasurface focuses energy into tissue, detecting glucose-related dielectric changes with high sensitivity. AI algorithms translate these signals into real-time metabolic data. Designed for wrist-worn devices, the system enables continuous, accurate, and comfortable glucose monitoring, offering a breakthrough alternative to finger-prick tests
