The sensor module and associated reference designs for consumer products integrate hardware and application firmware to enable wearable devices to monitor multiple biomarkers, including core body temperature, blood pressure, body hydration, alcohol, lactate, and glucose trends, among others. The full-stack, "clinic-on-the-wrist" digital health sensor system features a wristband that contains the sensor module and communicates with custom cloud-based analytical engines via a smartphone app. T
The wristband, says the company, 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," says Dr. Andrew Rickman, chief executive officer and founder of Rockley Photonics. "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. 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."
Through its "clinic-on-the-wrist" technology utilizing a miniaturized chip solution that provides continuous, non-invasive monitoring of core biomarkers, the company says that it expects to be able to overcome the key challenges associated with mobile wellness monitoring. While many of today’s wearable consumer electronic devices use green light-emitting diodes (LEDs) to monitor heart rate, Rockley’s infrared (IR) spectrophotometers can detect and monitor a much wider range of biomarkers, which could dramatically increase the functionality of wearable devices.
The central and differentiating element of the sensing system is a non-invasive sensor module based on the company's platform’s spectroscopy technology. Unlike more common spectroscopy solutions, which use broad-spectrum light sources, Rockley’s sensor module generates a large number of discrete laser outputs from a single silicon chip covering a broad optical band.
