: Electroencephalography (EEG) systems based on textile electrodes are increasingly being developed to address the need for more wearable sensor systems for brain function monitoring. Blink-related oscillations (BROs) are a new measure of brain function that corresponds to brainwave responses occurring after spontaneous blinking, and indexes neural processes as the brain evaluates new visual information appearing after eye re-opening. Prior studies have reported BRO utility as both a clinical and non-clinical biomarker of cognition, but no study has demonstrated BRO measurement using textile-based EEG devices that facilitate user comfort for real-world applications. : We investigated BRO measurement using a four-channel EEG system with textile electrodes by extracting BRO responses using existing, publicly available EEG data ( = 9). We compared BRO effects derived from textile-based electrodes with those from standard dry Ag/Ag-Cl electrodes collected at the same locations (i.e., Fp1, Fp2, F7, F8) and using the same EEG amplifier. : Results showed that BRO effects measured using textile electrodes exhibited similar features in both time and frequency domains compared to dry Ag/Ag-Cl electrodes. Data from both technologies also showed similar performance in artifact removal and signal capture. : These findings provide the first demonstration of successful BRO signal capture using four-channel EEG with textile electrodes, providing compelling evidence toward the development of a comfortable and user-friendly EEG technology that uses the simple activity of blinking for objective brain function assessment in a variety of settings.
基于纺织电极的脑电图（EEG）系统正在不断发展，以满足对用于脑功能监测的更可穿戴传感器系统的需求。眨眼相关振荡（BROs）是一种新的脑功能测量指标，它对应于自发眨眼后出现的脑电波反应，并在大脑评估睁眼后出现的新视觉信息时对神经过程进行索引。先前的研究报告了BRO作为认知的临床和非临床生物标志物的效用，但没有研究证明使用基于纺织物的EEG设备进行BRO测量，这种设备能提高用户在实际应用中的舒适度。：我们通过使用现有的公开可用EEG数据（n = 9）提取BRO反应，研究了使用带有纺织电极的四通道EEG系统进行BRO测量。我们将基于纺织电极获得的BRO效应与在相同位置（即Fp1、Fp2、F7、F8）使用相同EEG放大器收集的标准干Ag/Ag-Cl电极的BRO效应进行了比较。：结果表明，与干Ag/Ag-Cl电极相比，使用纺织电极测量的BRO效应在时域和频域均表现出相似的特征。两种技术的数据在去除伪迹和信号捕获方面也表现出相似的性能。：这些发现首次证明了使用带有纺织电极的四通道EEG成功捕获BRO信号，为开发一种舒适且用户友好的EEG技术提供了有力证据，该技术利用简单的眨眼活动在各种环境中进行客观的脑功能评估。
