Objective. In this report we present the fEEGrid, an electrode array applied to the forehead that allows convenient long-term recordings of electroencephalography (EEG) signals over many hours. Approach. Twenty young, healthy participants wore the fEEGrid and completed traditional EEG paradigms in two sessions on the same day. The sessions were eight hours apart, participants performed the same tasks in an early and a late session. For the late session fEEGrid data were concurrently recorded with traditional cap EEG data. Main results. Our analyses show that typical event-related potentials responses were captured reliably by the fEEGrid. Single-trial analyses revealed that classification was possible above chance level for auditory and tactile oddball paradigms. We also found that the signal quality remained high and impedances did not deteriorate, but instead improved over the course of the day. Regarding wearing comfort, all participants indicated that t...

柔性印刷的额头脑电图传感器(fEEGrid),用于长期脑电图采集。

目的。在本报告中,我们介绍了fEEGrid,这是一个应用于额头的电极阵列,可以在多个小时内方便地长期记录脑电图(EEG)信号。方法。二十名年轻,健康的参与者戴着fEEGrid,并在同一天的两次会议中完成了传统的EEG范例。每节课相隔八个小时,参与者在早期和后期都执行相同的任务。对于后期会议,fEEGrid数据与传统的上限EEG数据同时记录。主要结果。我们的分析表明,fEEGrid可以可靠地捕获与事件相关的典型电位响应。单项试验分析表明,对于听觉和触觉奇异球范例,分类可能高于偶然水平。我们还发现,信号质量仍然很高,并且阻抗并没有恶化,而是在一天当中不断改善。关于佩戴舒适度,所有参与者均表示,...
