Abstract :
In this paper, we present a miniaturized (<;6cm3) and low noise (60nV/√Hz) wireless EEG sensor node with active electrodes and simultaneous electrode tissue impedance (ETI) monitoring. The added benefit of the active electrodes and continuous ETI monitoring is quantified in terms of susceptibility against power line interference and cable motion artefacts. The sensor node is benchmarked against a reference system for similarity measures in EEG frequency response in the relevant bandwidth. Applications of this prototype are foreseen in the clinical, lifestyle and entertainment domains.
