摘要

可穿戴脑电图(EEG)系统可以监测神经活动，实现新的脑机接口，并帮助用户与辅助设备进行交流。为了便于动态EEG记录，最近的研究将干电极集成到可穿戴式耳机和耳塞中[1]，[2]。干电极比需要磨料皮准备的湿电极具有优越的易用性。然而，由于其高电极-皮肤阻抗(ESI)，干电极可穿戴设备容易受到运动伪影的影响。

A 6.8µW AFE for Ear EEG Recording with Simultaneous Impedance Measurement for Motion Artifact Cancellation

Wearable electroencephalography (EEG) systems can monitor neurological activity, enable new brain-computer interfaces and help users communicate with assistive devices. To facilitate ambulatory EEG recording, recent work has incorporated dry electrodes into wearable headsets and earbuds [1], [2]. Dry electrodes have superior ease-of-use over wet electrodes that require abrasive skin preparation. However, due to their high electrode-skin impedance (ESI), dry electrode wearables are susceptible to motion artifacts.
