Abstract：Intheresearchofbrain-computer interface（BCI），thehaironthescalpsurfacerestrictstheabilityof traditional scalp electroencephalogram（EEG） electrodes to capture neural signals.Ear-EEG electrodes effectively avoid contact with hair and can collect EEG signals comparable to those obtained from the scalp，offring a novel approach to EEG signalacquisition.This article systematically reviews.The recent progres inear-EEG electrodes is systematicaly reviewed，focusing on theirdesign principles and key performance of various in-ear electrodes and around-ear electrodes.It also discusses the advantages and limitations ofear-EEG electrodes compared with traditionalscalpEEGelectrodes，aswellasmethods toddresstheselimitations.Furthermore，thisreviewprospectsfor thefuturedevelopment directions ofear-EEG electrodes，pointing outthe opportunities and challenges they face.
