System and Method for Non‑Invasive Glucose Monitoring Using Near Infrared Spectroscopy

Technology Overview: This technology provides a non‑invasive glucose monitoring system based on near‑infrared (NIR) spectroscopy, eliminating the need for fingersticks or implanted sensors. The system analyzes optical absorption and scattering characteristics of biological tissue to correlate spectral signatures with blood glucose levels. Advanced signal processing enables continuous or on‑demand measurements while minimizing interference from physiological variability. The approach is designed to improve patient compliance and long‑term disease management without compromising measurement reliability.

Industry Pain Point: Current glucose monitoring methods are invasive or minimally invasive, causing discomfort, compliance challenges, and long‑term skin complications.

NJIT Solution: This technology enables truly non‑invasive glucose monitoring, supporting painless and repeatable measurements suitable for daily use.
