Speckle sensing for vital sign monitoring in automotive and health

Speckle-based optical sensing is redefining non-invasive vital sign monitoring. Unlike conventional PPG (photoplethysmography), this technology uses coherent laser illumination to generate dynamic speckle patterns on tissue, enabling precise measurement of heart rate variability, respiration, blood oxygen saturation, and blood pressure—even at a distance. Clinical validation shows signal quality up to 2x higher than state-of-the-art solutions, with robust performance across all skin tones and ambient light conditions. Advanced algorithms enable dynamic region-of-interest selection and motion artifact compensation, supporting reliable multi-subject monitoring in real-world environments.

The impact is profound: inclusive sensing eliminates disparities for people with darker skin, remote monitoring reduces patient discomfort and stress, and multi-subject capability supports rapid triage and disaster response. By enabling unobtrusive, clinical-grade monitoring in vehicles, hospitals, homes, and public spaces, speckle-based sensing empowers early detection, continuous care, and improved outcomes—transforming healthcare for diverse populations and advancing the future of accessible, high-quality health.
