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.

用于可靠的脑电图测量的脑电图帽的设计和表征。

在这项研究中，设计并制造了一种新型的带有蜡烛状微针电极（CME）的帽子型脑电图（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信号的挑战之一是将电极固定在皮肤上，即设计好的EEG耳机。CME能够与不同大小和形状的头部的头皮保持良好的接触，而EEG-Hat的遮盖机构可分离头发，并确保CME与头皮之间的良好接触。通过简单，简短的设置过程，从头皮上的五个测量点成功地同时测量了脑电信号。
