Oxford, England-based Rockley Photonics designed its band with short-wave infrared (SWIR) biosensing technology. It uses the company’s proprietary photonic integrated circuit (PIC) chipset. The company incorporated the SWIR spectrophotometer into a wearable wristband capable of several days of measurement.
According to a news release, the band provides the continuous collection of spectral data. The company says it offers unique insights into tissue composition and dynamics.
The platform offers real-time streaming of SWIR-based biomarkers of body temperature and hydration. It also uses LED-based photoplethysmography (PPG) biomarkers to measure heart rate, heart rate variability, respiratory rate and blood oxygen saturation. Rockley Photonics combined it with its Developer API to enable real-time monitoring of vital physiologic parameters.
“We are thrilled to usher in the next generation of health monitoring with wearable laser-based technology,” Rockley Photonics Chair and CEO Dr. Andrew Rickman said. “Rockley has created the full technology stack from the design of the PIC, which forms the miniature spectrophotometer, to the full wearable integration and novel biomarker delivery. We have significantly progressed the SWIR-tissue measurement science and biomarker algorithms through IRB-approved human studies.
“As we have recently demonstrated with our non-invasive glucose sensing and cuffless blood pressure studies, laser-based biosensors will continue to expand and enhance our understanding of human health.”
