EEG sensor system development

The raw data for the proposed manuscript 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.本研究拟投稿的论文题为《面向潜在脑机接口应用的固体聚乙烯醇-甘油-氯化钠接触凝胶与3D打印银涂层聚乳酸电极脑电图（EEG）传感器系统研发》，其原始数据集可在此处获取。在"电学特性"文件夹中，包含了所研发接触凝胶的电导率测量结果、PVAgel-AgPLA与电极-皮肤界面的阻抗谱测量结果。"脑电图（EEG）"文件夹内以CSV格式存储了稳态视觉诱发电位（SSVEP）与α波（alpha wave）检测的脑电数据流。采样率为500 Hz，每1比特对应0.536微伏（μV）。
