Flexible Silver/Carbon Nanotube‐Graphene Oxide‐Polydimethylsiloxane Electrode Patch for Electroencephalography Language

A flexible silver/carbon nanotube-graphene oxide-polydimethylsiloxane (Ag/CNT-GO-PDMS) patch electrode for recording electroencephalography (EEG) signals and recognizing words is prepared. These patches record EEG under the synergistic sensing mechanism of noncontact capacitance mode CNT-GO-PDMS contact current Ag claws, with low scalp resistance 6.4 kΩ. In occipital region, signal-to-noise ratios (SNR) are ≈90 dB α-waves 9 visual-evoked signals; SNR auditory-evoked in temporal region ≈10 dB. The cap comprises seven Ag/CNT-GO-PDMS to steady-state potentials (SSVEP) multiple auditory response (MASSR). can recognize nine (“one” “nine”) SSVEP–MASSR paradigm, a visual accuracy 90.4% 54.0%. statistical analysis also shows that stimulation frequency channel significant influencing factors word recognition. We developed standardized process herein propose new strategy identify words, which great significance establishment language database application field information transmission.
