Developing reliable and user-friendly electroencephalography (EEG) electrodes remains a challenge for emerging real-world EEG applications. Classic wet electrodes are the gold standard for recording EEG; however, they are difficult to implement and make users uncomfortable, thus severely restricting their widespread application in real-life scenarios. An alternative is dry electrodes, which do not require conductive gels or skin preparation. Despite their quick setup and improved user-friendliness, dry electrodes still have some inherent problems (invasive, relatively poor signal quality, or sensitivity to motion artifacts), which limit their practical utilization. In recent years, semi-dry electrodes, which require only a small amount of electrolyte fluid, have been successfully developed, combining the advantages of both wet and dry electrodes while addressing their respective drawbacks. Semi-dry electrodes can collect reliable EEG signals comparable to wet electrodes. Moreove...

用于脑电图记录的半干电极回顾

开发可靠且用户友好的脑电图 (EEG) 电极仍然是新兴现实世界脑电图应用的挑战。经典的湿电极是记录脑电图的黄金标准；然而，它们难以实现并且让用户感到不舒服，从而严重限制了它们在现实生活场景中的广泛应用。另一种选择是干电极，它不需要导电凝胶或皮肤准备。尽管它们的快速设置和改进的用户友好性，干电极仍然存在一些固有问题（侵入性、相对较差的信号质量或对运动伪影的敏感性），这限制了它们的实际应用。近年来，仅需要少量电解液的半干式电极已成功开发，结合湿电极和干电极的优点，同时解决它们各自的缺点。半干电极可以收集与湿电极相当的可靠 EEG 信号。更...
