BrainBit offers 4 EEG dry electrodes, 1 reference and 1 common sensor, achieving a higher spatial resolution on brain activity than any available device on the consumer market.
The system digitizes analogue EEG signals collected by electrodes, amplifies them via Bluetooth connectivity, and transfers the physiological brain data of individuals to a dedicated host computer, mobile device, or cloud backend.
In contrast with analogous devices, BrainBit follows the international 10 – 20 electrode placement protocol, with electrodes mounted inside the headband. Each electrode makes direct contact at the T3 and T4 temporal lobe regions as well as at the O1 and O2 occipital lobe regions. According to current research and international best practices, these specific regions provide the best access to high-fidelity signals for the four main types of brain waves. The BrainBit headband monitors electrical activity that is produced from the cortical regions of the brain and records the activity as raw EEG data. For user readability, this data is presented as wavelengths across four different frequency channels representing unique mental conditions.
