EEG headset

Wearable neurotech that translates brainwave patterns (EEG) into actionable data for cognitive monitoring and direct brain-computer interfacing.

These systems utilize non-invasive electrodes (typically 5 to 32 channels) to record voltage fluctuations from neuronal activity. Hardware from providers like EMOTIV or OpenBCI tracks specific frequency bands: Alpha waves (8 to 12 Hz) for relaxation and Beta waves (12 to 30 Hz) for active concentration. Researchers use this high-resolution data to map mental states or execute BCI (Brain-Computer Interface) commands: moving a cursor or triggering a robotic arm via thought. Modern units favor dry-sensor arrays to bypass messy conductive gels, streamlining setup for clinical trials and software development.
