Through this channel, we share our knowledge, materials, results and products that emerged from our earables research. A lot of what we do uses electrophysiological signals (EEG, EOG, ECG, EMG - ExG in short). All that we offer is available under open-source licenses to provide maximum access.

OpenBCI ExG Headphones Kit

This kit allows the recording of electrophysiological changes from electrodes around the ears and on the head. You know - while looking like a pair of headphones instead of an alien EEG-helmet or -cap!

As this is an open-source project, we share all our build instructions in the GitHub repository. At the same time, we are aware that some people might prefer purchasing a kit for easier and faster access. Hence, we are considering to offer such a kit - if we get a few requests. If you are among the interested, please just send us a short message via contact@expeeeriments.io

OpenBCI-cEEGrid Kit

The maximum quality ear-ExG system: Combining cEEGrids and the OpenBCI biosensing boards, you can easily realize earables studies with gelled, and lightweight electrodes.

Open-cEEGrid Replacements

Need more cEEGrid electrodes for your project? We offer the Open-cEEGrid (gold-plated) replacements!

Worried about the recording suitability? This recent research highlights lower impedance of gold (Au) electrodes in the 1-1000Hz region than Ag/AgCl (but higher impedances <1Hz). At the same time, gold electrodes are known to polarize which can make ERP recordings difficult.

Therefore, we recommend our gold-plated Open-cEEGrids for oscillatory EEG (frequency band power) and EMG recordings.
