BrainAccess Development Kit

Compact solution for brain-computer interface (BCI) systems based on dry electroencephalography (EEG)

BrainAccess is a kit intended for researchers and developers who need an easy-to-use and reasonably-priced EEG solution for BCI applications.

Available as BrainAccess Standard Kit and BrainAccess Extended Kit which include electroencephalographs, headwear with a set of dry-contact electrodes and software for EEG signal acquisition and processing. The kits also include ready-to-use algorithms which can be used for BCI applications.

Electroencephalographs

These models of electroencephalographs are available:

Both BrainAccess MINI and BrainAccess MODULAR are multi-channel electroencephalographs with a common reference channel. They also feature a driven bias electrode connection for improved noise reduction capabilities.

BrainAccess MINI

BrainAccess MINI is a truly portable device, which is ideal for an in-field EEG applications and research. It has long battery life, weighs less than 100 grams and can be directly mounted on BrainAccess CAP.
