Low power wireless EEG headset for BCI applications

Miniaturized, low power and low noise circuits and systems are instrumental in bringing EEG monitoring to the home environment. In this paper, we present a miniaturized, low noise and low-power EEG wireless platform integrated into a wearable headset. The wireless EEG headset achieves remote and wearable monitoring of up to 8 EEG channels. The headset can be used with dry or gel electrodes. The use of the headset as a brain computer interface is demonstrated and evaluated. In particular, the capability of the system in measuring P300 complexes is quantified. Applications of this prototype are foreseen in the clinical, lifestyle and entertainment domains. © 2011 Springer-Verlag
