摘要: Electroencephalography (EEG) can provide important and useful information in clinical diagnosis. The conventional EEG electrode with conductive gel (wet electrode) is most frequently used for measuring EEG. However, the wet electrode encounters the issue of dehydration for long-term measurement. Recently, different types of dry electrodes were proposed to overcome the above issue, but measuring EEG in a hairy site is still a challenge for these electrodes. In this paper, a novel noncontact dry electrode with adaptive mechanical design is proposed to measure EEG in a hairy site without conductive gel. The proposed noncontact dry electrode can measure EEG across the hair layer to reduce the influence of hair. By the adaptive mechanical design, the influence of motion artifact can also be effectively improved. From the experimental results, the proposed noncontact dry electrode can provide a good performance of measuring EEG in a hairy site and a good ability to avoid the influence of motion artifact.
