Rockley Photonics continues to make rapid progress towards noninvasive glucose sensing using its proprietary silicon photonics platform. The technology platform enables short-wave infrared (SWIR) spectroscopy to be translated to a miniaturized, wearable form factor capable of making noninvasive biomarker measurements in humans. Through a combination of benchtop sensor verification with both simulated human skin and during preliminary human studies, Rockley has engineered the SWIR platform to measure glucose.

Recent measurements performed using Rockley?s PIC technology in a benchtop version with a complex simulated tissue model showed that the technology is capable of measuring glucose with an accuracy of 5mg/dL. The results of an initial IRB-approved study involving 40 Type I and Type II diabetic subjects over a 10-week period also demonstrated significant progress towards the development of a noninvasive wearable glucose monitor. The study was conducted with attention to avoid spurious correlations and allowed for critical technology performance characteristics to be determined.
