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.
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.
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.
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.
