Noninvasive subterahertz glucose monitoring using a communication inspired eye diagram.

ABSTRACT: The global prevalence of diabetes mellitus (DM) continues to rise, highlighting the need for noninvasive, painless continuous blood glucose monitoring to support disease management and reduce long-term complications. Here, we report noninvasive subterahertz (sub-THz) glucose monitoring using communication-inspired eye diagram (sub-THz GlucoEye). The method detects distortion in the modulation pattern of sub-THz carrier signals reflected from the fingertip, resulting from relaxation time variations in the hydration water surrounding glucose molecules. These distortions are analyzed using multivariate regression analysis, based on variations in the modulation pattern's performance parameters represented in the three-dimensional eye diagram. Compared to conventional THz spectroscopy, which on
