我们开发了一种多通道肌电传感器系统，能够接收和处理来自多达32个植入式肌电传感器（IMES）的信号。肌电控制的植入式传感器的吸引力在于可以在其源处测量肌电图（EMG）信号，从而提供相对无串扰的信号，其可以被视为独立的控制部位。外部遥测控制器接收由植入电极通过经皮磁链路发送的遥测。相同的链路为植入的电极提供电力和命令。通过植入残余肌肉组织中的传感器对EMG信号进行无线遥测，消除了与经皮导丝相关的问题，例如感染、断裂和造袋术。每个植入式传感器由一个定制设计的应用指定的集成电路组成，该集成电路被封装到Alfred E.曼恩基金会。植入物设计用于永久性长期植入，无维修要求。我们有一个完整的操作系统。该系统已在动物身上进行了测试。植入物已被长期植入三只猫的腿部，植入后四个月仍然完全运作。
We have developed a multichannel electrogmyography sensor system capable of receiving and processing signals from up to 32 implanted myoelectric sensors (IMES). The appeal of implanted sensors for myoelectric control is that electromyography (EMG) signals can be measured at their source providing relatively cross-talk-free signals that can be treated as independent control sites. An external telemetry controller receives telemetry sent over a transcutaneous magnetic link by the implanted electrodes. The same link provides power and commands to the implanted electrodes. Wireless telemetry of EMG signals from sensors implanted in the residual musculature eliminates the problems associated with percutaneous wires, such as infection, breakage, and marsupialization. Each implantable sensor consists of a custom-designed application-specified integrated circuit that is packaged into a bio-compatible RF BION capsule from the Alfred E. Mann Foundation. Implants are designed for permanent long-term implantation with no servicing requirements. We have a fully operational system. The system has been tested in animals. Implants have been chronically implanted in the legs of three cats and are still completely operational four months after implantation.
