Abstract

In this paper, the design of an electroencephalogram (EEG) patch on forehead with a portable multi-channel EEG acquisition system are presented. On one hand, the proposed ultra-thin soft electrode, which uses dopamine-modified platinum/silver core-shell nanowires (Dopa-Ag@Pt NWs) as the conductive materials, has strain-tolerated high conductivity, anti-oxidation ability and adhesive ability. On the other hand, a portable multi-channel EEG acquisition system including pre-amplifier and microcontroller is developed. The pre-amplifier employs a two-stage amplification design and filter fits the frequency band of a variety of electrophysiological signals with reduced interference of noise. The microcontroller enables real-time, 8-channel monitoring in a small volume. By combining the proposed electrode with the circuitry, an cost-effective multi-channel EEG measurement system with robust skin compliance, anti-oxidation capability, low noise, and low power consumption has been realized.
