Noninvasive Raman device tracks blood glucose accurately in under a minute

MIT researchers developed a compact band-pass Raman spectroscopy device that noninvasively tracks glucose through the skin in under a minute using physically interpretable optical signals. In a pilot study and tissue phantom validation, the system showed glucose measurements comparable to commercial continuous glucose monitors, supporting further clinical evaluation.

Noninvasive Glucose Monitoring Research at MIT Shows a Path Toward Wearable Health Integration

Researchers at MIT have developed a system for noninvasive glucose monitoring that uses a compact optical device to measure blood sugar without piercing the skin. The method relies on Raman spectroscopy, a technique that captures how light scatters when it interacts with tissue. By analyzing the resulting signal, the device can infer glucose levels beneath the skin surface. The prototype is currently larger than consumer wearables, but the resea…
