Abstract

We have recently developed a conformable solid state material solution (carbon nanofiber filled polydimethylsilisoxane, CNF-PDMS) for electroencephalography (EEG) electrodes. In this study, we tested the efficacy of electrodes molded from this material to record well studied neural phenomena using a battery of standard laboratory tasks. Event related potential (ERP) and eyes open/closed results show performance matching that of commercially available metal-pin based dry EEG electrode, while summary statistics (correlation and RMSE) show matched and even improved ability to track local and global fluctuations in EEG. We present baseline data that demonstrates CNFPDMS is a viable solution for conformable, safe, dry EEG electrodes.
