A novel hybrid bioelectrode module for the zero-prep EEG measurements

This paper discusses a novel hybrid EEG biosensor module that measures through-hair EEG with zero preparation of the scalp. The biosensors can be donned or doffed quickly by the wearer, requiring no skin preparation, produce no skin irritation, and be comfortably worn for an extended period. The proposed EEG sensor is fabricated by the injection molding process with a flexible base and biofriendly materials. The noninvasive nature of BRCNCTU´s EEG system [1] (i.e. zero skin preparation, minimal wiring) permits greater subject freedom of motion and considerably improves user compliance for such systems. This effort culminates in a biomonitoring system, measuring EEG, EOG, ECG and EMG signals for real time monitoring of human-computer interactions.
