皮层微创脑机接口传感器发展现状与趋势

Development status and trends of minimally invasive cortical brain-computer interface sensors

脑机接口(Brain-Computer Interface,BCI)传感器作为脑电信号采集与调控的前端器件,是BCI技术的核心基础部件之一。其中,皮层微创BCI传感器贴附在硬脑膜上或硬脑膜下,未进入脑组织,植入安全性高。此类传感器通常用来采集来自大脑皮质区域(如运动区、视觉区、语言区)的信号,这为许多其他脑功能和一般BCI应用(如皮质康复)开辟了可能性,已成为近年来科研与临床应用的焦点。因此,聚焦皮层微创BCI传感器在商业及科研领域的发展现状,并对未来技术及应用趋势进行分析和展望,能为BCI学术和产业界提供参考和借鉴。

As a vital element in brain-computer interface(BCI)technology,sensors serve as the front devices for electroencephalogram acquisition and regulation.Among them,the minimally invasive cortical BCI sensors can attach epidurally or subdurally without penetrating into the brain tissue,ensuring the safe implantation.These sensors are typically employed to collect signals from specific cortical areas including movement,vision,and language,which open up possibilities for various brain functions and general applications like cortical rehabilitation,as well as the focus of scientific research and clinical application.Therefore,focusing on the current development status of minimally invasive BCI sensors in both business and research domains,and analyzing and looking forward to future technologies and application trends,can provide reference and inspiration for the academic and industrial fields of BCI.
