Multi-Position Dry EEG Headband

The Cognionics Multi-position Headband is a designed to be a simple, flexible dry EEG experimental platform. The system is intended for use with our research grade Miniature Wireless EEG Data Acquisition System, Flex and Drypad sensors to provide low-noise, reliable dry electrode recordings.

The headband is fully reconfigurable for different experiments and applications. Sensors can be attached and moved to any of the 12 positions along the circumference of the headband to measure signals from the frontal, occipital and temporal regions. A highly elastic fabric ensure comfort, fit across a wide variety of head sizes and provides contact pressure for the dry electrodes.
