Electrooculogram (EOG) is a measurement technique to record the biopotential signals induced by eyeball movement and EOG signals are critical for the development of wearable medical sensors and also interfaces for human-computer interaction. Unlike traditional "wet" electrodes which profoundly hinder the development of wearable EOG sensors, in this study, we report for the first time the use of graphene-coated fabric electrodes for EOG acquisition and overcome the limitations of conventional "wet" electrodes. We demonstrate the proof-of-concept of graphene textile electrodes for EOG acquisition with side-by-side comparison to conventional Ag/AgCl electrodes.
