Device capable of being mounted on head and with electrodes for electroencephalogram

Abstract

The invention provides a device capable of being mounted on the head and with electrodes for the electroencephalogram based on the electrode which can be adjusted in the radial direction. The device is used for matching the unique size and shape of the head of a wearer. The device which is provided with an electrode array which is arranged in the device and can be mounted on the head comprises mounting parts which can be mounted on the head, and the mounting parts are mutually connected by mechanical fasteners to be convenient for the adjustment of the size and the position of the device which can be mounted on the head. An elastic sleeve array is arranged in a part of each mounting part which can be mounted on the head. A single electrode is accommodated in each sleeve array which is deformable for self orientation. The deformation of the sleeves causes the center shaft of the single electrode accommodated in the elastic sleeve to be maintained at the position nearly perpendicular to the plane tangent line of the scalp part relatively positioned below the electrode. 基于径向可调节的电极提供了一种可头部安装并具有脑电图用电极的装置，以匹配佩戴者独有的头部尺寸和形状。具有设置在其中的电极阵列的可头部安装的装置包括可头部安装的装置部分，其通过机械紧固件互连以方便可头部安装的装置的尺寸和位置调节。每个可头部安装的装置部分中设有弹性套筒阵列。每个弹性套筒容纳单个电极，且为可变形的以自定向。套筒的变形使得穿过容纳在弹性套筒内的单个电极的中心轴维持在相对位于电极下的头皮部分的平面切线近似垂直的位置处。
