- Conventional Ag/AgCl wet-gel electrodes suffer from a number of drawbacks when used for electroencephalogram (EEG) recoding, particularly for long-term monitoring applications. A simultaneous comparison is made between ultra-high impedance capacitive electric potential sensors (EPS) and conventional wet-gel electrodes using a commercial EEG system. Both free running (spontaneous) and evoked (event related) EEG signals were recorded and cross-correlated. Correlations of greater than 0.9 were observed for both sets of data. The potential advantages of this new approach are discussed and include a reduced set-up time, elimination of cross sensor coupling and skin irritation caused by AgCl gel.
