“…A simple and less probes-based EEG system takes less computational power and results in compromised security, that is why not a potential candidate [ 15 , 16 , 17 , 18 , 19 , 20 ]. Researchers [ 21 , 22 , 23 , 24 , 25 ], propose wet EEG electrodes for high signal accuracy, calibration and less noise, interference unlike the dry leads.…”
