Rockley Photonics unveils spectrophotometer-on-a-chip module

Rockley Photonics revealed its complete full-stack, “clinic-on-the-wrist” digital health sensor system based on its own spectroscopy technology. Rockley’s sensor module generates a large number of discrete laser outputs from a single silicon chip covering a broad optical band. The sensor non-invasively probes beneath the skin to analyze blood, interstitial fluids, and various layers of the dermis for constituents and physical phenomena of interest. The company says its device delivers several milliwatts of optical output power per wavelength channel, which is key to achieving the high signal-to-noise ratio required for signal analysis from a small wearable.

Rockley’s full-stack sensing solution features a wristband that contains the sensor module and communicates with custom cloud-based analytical engines via a Rockley smartphone app. The wristband will be used in a sequence of in-house human studies in the coming months.

“Our full-stack sensor solution, which brings together optical and electronic hardware, firmware, algorithms, and cloud-based analytics, is an exciting milestone on our roadmap. Our reference designs will significantly aid our customers and partners with the deployment of our technology and accelerate their own scalable, high-volume product delivery,” said Dr. Andrew Rickman, chief executive officer and founder of Rockley Photonics. “We believe that combining machine learning algorithms with continuous monitoring of an extended set of biomarkers from accessible wearable devices will provide new actionable insights to enhance and transform digital healthcare.”
