论文摘要
在过去的几年中,已经证明脑电图(EEG)可以从耳朵内部记录(耳塞脑电图)。为了打开低调耳机作为可穿戴的脑部计算机界面(BCIS)的门,这项工作为基于多个干电极电极,用户总设计设计以及用于流数据和设备编程的轻型无线界面提供了实用的入耳式脑电图设备。耳机设计用于改善大量用户的耳道接触,并根据标准技术(例如真空形成,等离子体处理和喷雾涂层)在低成本且可扩展的制造过程中制造。 2.5x2.5 cm^2无线记录模块旨在将数据无线记录和流传输到主机计算机。在三个月内对三个人类受试者进行了表现,并与临床级湿头皮脑电图记录进行了比较。提出了自发和诱发的生理信号,眼光,α节奏和听觉稳态反应(ASSR)的记录。这是我们所知的第一个无线脑EEG,融合了干燥的多电极,用户 - 元素设计。用户生成的耳朵脑电图记录了2.17的平均α调制,表现优于干电器内脑电图系统中最新的alpha。
In the past few years it has been demonstrated that electroencephalography (EEG) can be recorded from inside the ear (in-ear EEG). To open the door to low-profile earpieces as wearable brain-computer interfaces (BCIs), this work presents a practical in-ear EEG device based on multiple dry electrodes, a user-generic design, and a lightweight wireless interface for streaming data and device programming. The earpiece is designed for improved ear canal contact across a wide population of users and is fabricated in a low-cost and scalable manufacturing process based on standard techniques such as vacuum forming,plasma-treatment, and spray coating. A 2.5x2.5 cm^2 wireless recording module is designed to record and stream data wirelessly to a host computer. Performance was evaluated on three human subjects over three months and compared with clinical-grade wet scalp EEG recordings. Recordings of spontaneous and evoked physiological signals, eye-blinks, alpha rhythm, and the auditory steady-state response (ASSR), are presented. This is the first wireless in-ear EEG to our knowledge to incorporate a dry multielectrode, user-generic design. The user-generic ear EEG recorded a mean alpha modulation of 2.17, outperforming the state-of-the-art in dry electrode in-ear EEG systems.
