EEG sensor system development

The raw data for the published article titled: "EEG sensor system development consisting of solid polyvinyl alcohol-glycerol-NaCl contact gel and 3D printed, silver coated polylactic acid electrode for potential brain-computer interface use" can be found here. In the "Electrical properties" folder the results of the conductivity measurements of the proposed contact gel, the impedance spectroscopic measurements of the PVAgel-AgPLA and the electrode-skin interface are presented. The "EEG" folder contains the datastreams of the SSVEP and the alpha wave detection recordings in csv format. The sampling rate was 500 Hz and one bit is equal to 0,536 microV.
