Product Overview

Open-cEEGrid is a flexible, re-usable and convenient around-the-ear electrode array designed to sample EEG and other physiological signals.

  •  

    The Open-cEEGrid is designed to pair with the OpenBCI CytonDaisy 16-channel board (sold separately).

    Open-cEEGrids are a flexible, re-usable and convenient around-the-ear electrode array that capture EEG and other physiological phenomena. This biosignal acquisition system allows the discrete recording of electrophysiological changes (e.g., EEG, ECG, EMG) from inconspicuous electrodes positioned around the ears.

    Scientific Validation:

    Wearable electroencephalography (EEG) has the potential to improve everyday life through brain–computer interfaces (BCI) for applications such as sleep improvement, adaptive hearing aids, or thought-based digital device control.


    OpenBCI's mission is to democratize access to neuroscience research, knowledge, and tools. We partnered with researchers to export cEEGrid out of the lab and into the hands of anyone who wants to use EEG in real life. 

    Ear-centered EEG has been validated in a range of studies:
    • Debener et al. 2015: ERP and P300 data obtained via unobtrusive ambulatory EEG using a smartphone and cEEGrid
    • Bleichner and Debener 2017: cEEGrid enables the recording of meaningful continuous EEG, event-related potentials and neural oscillations
    • Holtze et al. 2022: Ear-EEG via mobile cEEGrid comparable to traditional high-density EEG caps for measurement of auditory attention to continuous speech
    Scientific validation of OpenBCI bio-amplifiers for ear-centered EEG:

    cEEGrids for sleep stage classification research:

    Information on recording suitability: Kurniawan et al. 2022 highlights lower impedance of gold (Au) electrodes in the 1-1000Hz region than Ag/AgCl. Gold electrodes are suitable for biosignal recordings like EEG.

    At the same time, gold electrodes are known to polarize, which can complicate ERP recordings. Therefore, the gold-plated Open-cEEGrids are recommended for oscillatory EEG (frequency band power) and ECG, EOG, and EMG recordings instead of ERP.
