چکیده :
Electroencephalography (EEG) is an evaluation of the electrical activity of the human brain. One of the primary challenges when recording EEG signals is its comfort and wearability for the user. Dry electrodes are a suitable alternative for commercially available wet Ag/AgCl electrodes due to the removal of conductive gel. Furthermore, with the increase in the number of channels, the electrode wires increase as well and make recording the signal more difficult. Electrode wires are used to transmit the EEG signal from the electrode to an amplifier. Due to the unwanted movements of the user, displacement of electrical wires introduces artifacts and noise in the received signal. It is preferred to integrate the electrodes and their electrical wires into an EEG cap or headband that can improve the level of user comfort. In this study, a novel textile-based electrode wire headband is designed and fabricated. Conductive copper wires are knitted into the fabric in a way that dry and wet electrodes can be conveniently interconnected. Thus, the technique prevents additional clutter of wires introducing the aforementioned artifacts. Various electrical and mechanical characterizations are performed on the fabricated sample to measure their electrical and elasticity performance compared to conventional electrical wires.
