For brain-computer-interface, it is essential to record continuous electroencephalograph (EEG) with high signal quality. In this paper, we introduced a novel EEG electrode that is composed of uniformly distributed carbon nanotube (CNT) embedded within adhesive polydimethylsiloxane (aPDMS). This compliant conductive electrode allows it to conform to the shape of contacting surface. Thus, EEG could be measured accurately even with hairs on the contacting surface. With the capacitive coupling in the interface between metal and CNT/ aPDMS composite, the insulation layer is controllable. Lastly, to amend the EEG quality, pillars were implemented and Parylene C layer was deposited as an insulation layer.
