Air

Air is a wearable and portable dry EEG device, designed for practical applications that require high levels of user comfort and discretion, as well as a quick setup and excellent signal quality for researchers.
Developed with 8 dry electrodes positioned over specific brain regions (prefrontal and occipital), it is optimized for the baseline assessment of emotional and cognitive states. Its high-performance active shielding and stable mechanical structure ensure exceptional robustness and EEG signal quality, even while in motion or during extended recording sessions.

What is included

Air EEG

8 dry-EEG sensors covering prefrontal and occipital areas. High signal quality and enhanced SNR through active shielding and an optimized DRL system.
