Hair-compatible sponge electrodes integrated on VR headset for electroencephalography

Figure 1. Design of our VR-EEG headset. (A) A schematic illustration of the PMA sponge electrodes integrated on a commercial VR headset to make good contact with the hairy scalp for EEG. The blue dash lines labeled on the VR headset strap indicate the outline of the FCA laminated on the other side of the strap; (B) A photograph of the PMA sponge electrodes; (C) A photograph of the FCA that connects all sponge electrodes to the back of the VR headset for connection to the data acquisition system; (D) An exploded view illustrating the installation of one PMA sponge on the VR headset through insertion into the open holes of the FCA, which is adhered to the strap by a double-sided elastomeric sticker; (E) The VR headset with nine PMA sponge electrodes integrated on it. EEG: electroencephalography; FCA: flexible connector array; PMA: poly (3,4-ethylenedioxythiophene) polystyrene sulfate/melamine; VR:virtual reality.
