Passive Digital Biomarkers: Enabling Continuous and Invisible Health Monitoring

Passive digital biomarkers are transforming modern healthcare by allowing health data to be collected automatically, without requiring patients to actively perform tests or report symptoms. These biomarkers represent a major shift toward continuous, real-world health monitoring powered by digital technologies.

What Are Passive Digital Biomarkers?

Digital biomarkers are objective physiological and behavioral data collected through digital devices such as smartphones, wearable sensors, and connected health technologies.

Passive digital biomarkers specifically refer to health data gathered without conscious effort from the user. For example, a smartwatch measuring heart rate or oxygen levels while a person goes about daily activities generates passive biomarker data automatically.

Near Infrared Imaging: Advancing Precision in Medical Visualization

Near infrared (NIR) imaging is a technology that uses light in the near-infrared spectrum to visualize biological tissues and structures. It is commonly used in surgical guidance, vascular imaging, and biomedical research.

Unlike visible light, near-infrared light can penetrate deeper into tissues. This allows clinicians to observe blood flow, lymphatic pathways, and tissue structures during medical procedures. Real-time imaging helps improve surgical precision and reduce complications.
