In this study, a new hat-type electroencephalogram (EEG) device with candle-like microneedle electrodes (CMEs), called an EEG-Hat, was designed and fabricated. CMEs are dry EEG electrodes that can measure high-quality EEG signals without skin treatment or conductive gels. One of the challenges in the measurement of high-quality EEG signals is the fixation of electrodes to the skin, i.e., the design of a good EEG headset. The CMEs were able to achieve good contact with the scalp for heads of different sizes and shapes, and the EEG-Hat has a shutter mechanism to separate the hair and ensure good contact between the CMEs and the scalp. Simultaneous measurement of EEG signals from five measurement points on the scalp was successfully conducted after a simple and brief setup process. The EEG-Hat is expected to contribute to the advancement of EEG research.
在本研究中，设计并制造了一种新型的带有蜡烛状微针电极（CME）的帽式脑电图（EEG）设备，称为EEG-Hat。CME是干式EEG电极，无需皮肤处理或导电凝胶即可测量高质量的EEG信号。测量高质量EEG信号的挑战之一是电极与皮肤的固定，即设计良好的EEG头戴设备。CME能够与不同大小和形状的头部头皮实现良好接触，并且EEG-Hat具有一个快门机制来分开头发并确保CME与头皮之间的良好接触。经过简单而短暂的设置过程后，成功地从头皮上的五个测量点同时测量了EEG信号。EEG-Hat有望为EEG研究的进展做出贡献。
