脑机接口硬件设备主要包括脑电采集设备、脑机接口芯片，以及电源、采集器、同步器、刺激器、解码 器等设备零部件。其中，脑机接口硬件设备最为核心的便是用于脑电信号采集或神经反馈的脑电采集设 备(即电极)，以及用于脑电信号处理的脑机接口芯片。脑机接口芯片分为侵入式和非侵入式两大类，其 中侵入式脑机接口芯片要求远高于非侵入式。在侵入式脑机接口中，芯片的主要功能包括数据读出和信 号激励，此外为了保证方便和外界沟通还需要使用无线传输。 | 数据或出 | 数据读出主要是指脑机接口从脑部该取特定区域的信号,并且在芯片上做一系列初步处理,包括滚波 | | --- | --- | | | 等。具体多少信号处理在芯片上做,多少传输到片外完成则取决于整个芯片的设计考量。例如,对于 | | | 一些需要做快速反应的脑机接口芯片(例如检测颠縮并快速介入),则需要把尽可能多的处理在芯片 | | | 上实现,以满足延迟的需求。此外,通常经过芯片处理的信号比起原始信号的数据量会小,因此脑机 | | | 接口片上处理部分和无线数据传输部分是一对重要的权衡对象;片上处理越简单,则相关电路逻辑面 | | | 积和功耗越小,但是需要无线传输的数据量就越 ...
