dry eeg for basic brain states estimation

Air

Wearable and portable dry-EEG device optimised to monitor basic cognitive and emotional states in real-world applications.

Wearable and portable dry-EEG device

Air is a wearable and portable dry EEG device designed for real-world applications that require great comfort and unobtrusiveness for the user, as well as an agile set up and outstanding signal quality for the researcher. Developed with with 8 dry electrodes over specific brain areas (pre-frontal and occipital), it is optimised for the basic estimation of emotional and cognitive states. Its high-performance active shielding and stable mechanical design provide outstanding robustness and EEG signal quality, even with movement or during long recording periods.

Owing to its exceptional usability, this dry-EEG can be easily self-placed in less than 2 minutes by the final user or, assisted by either technical or non-technical experts. This feature, in combination with the great comfort and reliability, is opening the door to the developing of real-world neurotechnology applications.

Air comes with Bitbrain Software Kit for EEG signal acquisition, processing and programming, which has a large compatibility with real-time I/O and third-party data processing (LSL, Matlab, Python, BCI2000, OpenVibe, etc). Also, by acquiring the Human Behaviour Research Lab, it can be performed a seamless synchronisation with other human monitoring technologies such as ExG, GSR, eye-trackers, among many others.

Main Components

EEG Headset

Light (130g) and flexible headset design that adapts to each head morphology (85% of the global population). It has 8 dry-EEG sensors with mechanical designs that reduce contact impedances and guarantee stable contacts, as well as an active shielding to maximise SNR.

EEG amplifier

Mobile, small and light (125gr) amplifier that records the EEG channels with a resolution of 24 bits at 256 Hz. It has an internal IMU (9 DOF) and online relative impedance control. With microSD recording or Bluetooth connectivity, a 10+ metre range, and up to 8+ hours continuous recording.

How to use

Use case: Seat - Neuroconfigurator

Clean, quick and easy set up by non-technical personnel in just a few minutes. This dry-EEG systems does not require expenses on consumables (jars of gels, syringes, shampoo, etc.), and there are no additional maintenance costs. It comes with an intuitive, powerful software platform to collect data with the help of visual cues to assure quality montage and monitoring.

1. Preparation: Connect the EEG to the amplifier, open the side strips and place the EEG on the head, aligning the central mark with the nose. Then slide it back to the most prominent zone of the head. Place the clip on the left ear lobe.

2. Set up: Wait 10 seconds and move the sensors that are not green yet to ensure they are in contact with the scalp. Repeat until there is good signal quality in all the sensors.

3. Test: Blink, bite, close your eyes, move your arms and walk around to check that the EEG is not affected.

4. Recording: Now you are ready to record your EEG data and to export it afterward.

5. Clean and storage: Clean the sensors with wet wipes and store Air in its own case.
