Portable and wireless EEG system

Hero is a portable dry-EEG system 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 9 dry electrodes over specific brain areas (fronto-central, central, and centro-parietal areas), it is optimized for the estimation of cognitive and sensorimotor states. Its high-performance active shielding and stable mechanical design provide outstanding robustness and signal quality, even with movement or during long recording periods. 

Owing to its refined usability, this dry electrode EEG technology can be easily self-placed in less than 2 minutes by the final user, or assisted either by technical or non-technical experts. This feature, in combination with the great comfort and reliability, is opening the door to neuroscience research in real-world applications, and real-life brain-computer interface products operated everywhere by final users, families, or assistants.  

Hero 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, indoor positioning system, among many others.

Main Components

Hero main components
EEG Headset

Light (250gr) and flexible headset design that adapts to each head morphology (85 perc global population). It has 9 dry-EEG sensors with mechanical designs that reduce contact impedances and guarantee stable contacts, as well as an active shielding to maximise SNR.

Integrated amplifier

The amplifier is already integrated into the device. It records with a resolution of 24 bits at 256Hz. It has an internal IMU (9 DOF) and online relative impedance control. With μSD recording or Bluetooth connectivity with a 10+ metre range, and 3+ hours continuous recording.

How to use

How to use it

Clean, quick and easy set up, also by non-technical personnel, in just a few minutes. This dry electrode technology 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: Measure the head from front (nasion) to back (inion) and from left to right to locate Cz. Use the band guides and the Cz reference to ensure that the EEG is centred. Swipe down until it is fully fitted. Place the clip on the ear lobe.
  2. Set up: The colour of each sensor indicates the quality of the EEG signal (online impedance). Carefully move the sensors to ensure they are in contact with the scalp. Wait 10 seconds and repeat with the sensors that are not green yet. 
  3. Test: Once there is good EEG signal quality, do a simple test to validate the signal quality: 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 you EEG data and to export it afterwards.
  5. Clean and storage: Clean the sensors with wet wipes and store Hero in its own case.
