Abstract

To expand the applications of the electroencephalogram (EEG), long-term measurement, a short installation time, and little stress on the participants are needed. In this study, we designed, fabricated, and evaluated an EEG headset with three candle-like microneedle electrodes (CMEs). The user is able to detach and reattach the electrodes, enabling long-term measurement with little stress. The design of the CMEs was experimentally determined by considering the skin-to-electrode impedance and user comfort. An EEG was successfully measured from areas with a high hair density without any preparation. The installation time was shorter than 60 s and the electrodes could be detached and reattached. The headset was designed such that the discomfort caused by its ear pads was higher than that caused by the electrodes. In 1 h experiments, the participants did not feel pain and the detachment of the CMEs was found to improve the comfort level of the participants in most cases. A successful demonstration of the long-term measurement of EEGs while watching a whole movie verified that the developed EEG headset with CMEs is applicable for EEG measurement in a variety of applications.

摘要

为了扩大脑电图（EEG）的应用范围，需要进行长期测量、缩短安装时间并减少受试者的压力。在本研究中，我们设计、制作并评估了一款带有三个烛状微针电极（CME）的EEG头戴设备。用户能够拆卸和重新连接电极，从而在几乎没有压力的情况下进行长期测量。通过考虑皮肤与电极之间的阻抗以及用户舒适度，通过实验确定了CME的设计。无需任何准备即可成功从高头发密度区域测量脑电图。安装时间短于60秒，并且电极可以拆卸和重新连接。头戴设备的设计使得耳垫引起的不适感高于电极引起的不适感。在1小时的实验中，受试者没有感到疼痛，并且发现在大多数情况下，CME的拆卸提高了受试者的舒适度。在观看整部电影时成功演示了EEG的长期测量，验证了所开发的带有CME的EEG头戴设备适用于各种应用中的EEG测量。
