Wireless EEG for the smart phone age

The Avatar recorder smart phone app frees researchers and their participants from being wired to a computer. Electrode signals can be viewed directly from a Bluetooth-enabled Android smart phone or tablet.


The Avatar recorder can collect EEG data with standard electrodes, including surface and subdural, and intracranial electrodes for animal research. It will record at 500–4000 Hz in eight channels, or up to 16,000 Hz with two channels. Events can be recorded with the optional TTL digital input.


The Avatar recorder can store data in multiple formats, including BDF, EDF, CSV, or binary to fit your workflow. Data is stored on a 32 GB removable microSD card, or transmitted to a computer or smart device for viewing or storage.


The Avatar recorder collects raw data in a variety of file formats so you can use a number of common software packages to view and analyze data, including MATLAB, EEGLAB, PRANA by PhiTools, Scientific tools for Python (SciPy), and EDFbrowser.
