May enable ambulatory cognitive monitoring; leaves open prospective validation before clinical adoption.
A compact, wearable wireless fNIRS system successfully detects forehead hemodynamic changes, offering a practical tool for real-time cognitive activity monitoring.
Victorio et al. (2025) studied Cognitive activity monitoring. Wearable wireless functional near-infrared spectroscopy (fNIRS) system was evaluated on Sensitivity to oxy- and deoxy-hemoglobin changes on the forehead region. A compact, wearable wireless functional near-infrared spectroscopy (fNIRS) sensor was sensitive to oxy- and deoxy-hemoglobin changes on the forehead region for monitoring neuronal activity.
