Diadem
Wearable dry-EEG headset optimised to monitor emotional and cognitive states in real-world applications with outstanding ease, comfort and reliability.
Wearable and mobile dry-EEG headset
Diadem is a portable EEG headset designed for real-world applications that require great comfort and unobtrusiveness for the user and an agile setup and outstanding signal quality for the researcher. Developed with 12 dry EEG electrodes over specific brain areas, it is optimised to estimate emotional and cognitive states (pre-frontal, frontal, parietal and occipital brain areas). 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 refined usability, this dry electrode EEG headset 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 its 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.
Diadem comes with the 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.

Outstanding usability
Quick and easy set up even by non-technical experts or the final user, almost anywhere and under any circumstance.
Optimised eeg electrode placement
Measure accurately frontal alpha asymmetry, occipital alpha -ERD/ERS, P300, N400, CVN, etc.
Robust dry-EEG monitoring
High-quality EEG that records with a resolution of 24 bits at 256Hz for 8+ hours thanks to active shielding with stable sensor contacts.
Practical technology
Easy to transport and store without maintenance or expenses on consumables.
High software compatibility
Intuitive software suite for users or SDK for programmers, and great compatibility with Matlab, Python, etc.
Main components
Dry-EEG headset
Light (190gr) and flexible headset design that adapts to each head morphology (85 perc global population). It has 12 dry-EEG sensors with mechanical designs that reduce contact impedances and guarantee stable contacts, as well as active shielding to maximise SNR.
EEG amplifier
Portable, small and light (125gr) amplifier that records the EEG channels at 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
Setup - Self-placement

How to use it
Clean, quick and easy set up by non-technical personnel in just a few minutes. This dry-EEG system 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 for signal acquisition with visual cues to assure quality montage and EEG monitoring.
- Preparation: Connect the EEG to the amplifier, open the side and top 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.
- 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.
- Test: Blink, bite, close your eyes, move your arms and walk around to check that the EEG is not affected.
- Recording: Now you are ready to record you EEG data and to export it afterwards.
- Clean and storage: Clean the EEG sensors with wet wipes and store Diadem in its own case.
