Wearable devices are highly effective at monitoring real-time physiological parameters such as heart rate, blood oxygen saturation, and other vital signs. While these measurements provide valuable information about the body's current state, some physiological changes develop gradually and may not be apparent from momentary readings alone.
One emerging approach is the measurement of Advanced Glycation End Products (AGEs) via skin autofluorescence. AGE-related signals are associated with long-term metabolic processes and can provide additional physiological context beyond traditional vital sign monitoring.
For engineers developing next-generation wearables and medical devices, the challenge is to integrate this capability into compact, robust systems. Recent advances in multi-wavelength optical components demonstrate how AGE measurement can be combined with established optical sensing functions within a single architecture, enabling both heart-rate monitoring and AGE assessment.
In our latest article, we explore how optical sensing technology enables non-invasive AGE measurement and why this supplementary vital sign could help expand the capabilities of wearable and point-of-care devices.
