ninjaNIRS – A Wearable fNIRS System

NinjaNIRS2024

NinjaNIRS is a modular and portable functional near-infrared spectroscopy (fNIRS) device designed for high-density, whole-head brain activity monitoring. It supports up to 200 optodes, with a maximum of 56 sources and 144 detectors, capable of dual-wavelength fNIRS data acquisition, enabling detailed mapping of brain activity.
