Abstract


Electrically conductive polyester fabrics are investigated in this work in order to develop textile electrodes for Eelectroencephalogram (EEG) measurement. Electrically conductive polyester fabrics have been prepared by electroless copper plating method. These fabrics are then characterized by SEM and XRD. The electrical conductivity of the fabric samples is also studied. The structural studies show that the crystalline region of fabric structure is not affected by the plating. The SEM studies reveal a very uniform deposition of copper on the fabrics. The conductivity studies show that the treated fabrics have good electrical conductivity.
The developed copper plated fabric was used to develop the textile electrodes for Eelectroencephalogram (EEG) measurement. The acquired signals were compared with commercially available electrodes and the signals were found to be similar. The good measurement performance exhibited by the textile electrodes indicates that they are feasible candidates for EEG recording, opening the door for long-term EEG monitoring applications.
