脑机接口(BMI)是一种新的人机界面方法，它使我们能够控制机器并与他人进行交流，而不需要输入设备，而是直接利用大脑信号。此前，我们成功开发了一种使用基于大脑表面电极的脑机接口来操作机器人手臂的实时控制系统，目的是恢复肌萎缩侧索硬化症患者等严重残疾人的运动和通信功能。为了减少感染的风险，一个完全可植入的无线系统对于侵袭性BMI的临床应用是不可或缺的。该系统包括两个通道集成模拟放大器芯片、蓝牙无线数据传输电路、无线充电电池、三维组织贴合高密度电极、钛头壳和氟聚合物体壳等许多新技术。本文描述了临床应用的BMI系统的第一个原型的主要特征。
The brain-machine interface (BMI) is a new method for man-machine interface, which enables us to control machines and to communicate with others, without input devices but directly using brain signals. Previously, we successfully developed a real time control system for operating a robot arm using brain-machine interfaces based on the brain surface electrodes, with the purpose of restoring motor and communication functions in severely disabled people such as amyotrophic lateral sclerosis patients. A fully-implantable wireless system is indispensable for the clinical application of invasive BMI in order to reduce the risk of infection. This system includes many new technologies such as two 64-channel integrated analog amplifier chips, a Bluetooth wireless data transfer circuit, a wirelessly rechargeable battery, 3 dimensional tissue-fitting high density electrodes, a titanium head casing, and a fluorine polymer body casing. This paper describes key features of the first prototype of the BMI system for clinical application.
