EMG/NIRS Wearable device

This device seamlessly integrates Near-Infrared Spectroscopy (NIRS) and Electromyography (EMG), enabling real-time monitoring of muscle oxygenation, blood flow, and electrical activity. These complementary modalities offer unparalleled versatility in understanding muscle performance, neuromuscular health, and hemodynamic changes, making it an indispensable tool for clinical diagnostics, sports training, rehabilitation, and academic research.

NIRS enables the measurement of oxygenation and hemodynamic changes in muscles or the brain by analyzing near-infrared light absorption.

EMG detects electrical activity in muscles, aiding in the evaluation of muscle activation, fatigue, and neuromuscular health.
