Characterization and cEEGrid Origin

ear-EEG 方法表征、隐蔽小型电极、cEEGrid 起点论文和 auricle soft electronics 旁支。

这一组解决什么问题

这一组解释 ear-EEG 方法边界、miniaturized electrode 过渡路线，以及 cEEGrid 如何从柔性耳周电极和移动采集系统中出现。

Mikkelsen 2015 是方法学边界，Bleichner 2015 是 miniaturized / concealed EEG 前身，Debener 2015 是 cEEGrid 起源，Norton 2015 是 auricle soft electronics 旁支。

cEEGrid 不是凭空出现，也不是 in-ear EEG 的同义词；它是 around-the-ear / ear-centered EEG 在多通道柔性电极上的一个代表实现。
