OpenNIRScap: An Open-Source, Low-Cost Wearable Near-Infrared Spectroscopy-based Brain Interfacing Cap

Project Overview This project introduces a low-cost, ergonomic functional Near-Infrared Spectroscopy (fNIRS) device designed for real-time brain activity monitoring. fNIRS is a non-invasive technique that uses near-infrared light to measure changes in blood oxygenation, providing insights into neural activity based on the modified Beer-Lambert Law. While conventional fNIRS systems are expensive, bulky, and limited to clinical environments, this system is designed to be accessible, accurate, and user-friendly—ideal for education, personal health tracking, and portable research applications.…
