Myoelectric pickups (electrodes and processors for detecting the signal that is recorded as an electromyogram) are the most important human-machine interface for controlling powered upper-extremity prostheses. This article presents a simple explanation of myoelectric signal acquisition and then discusses how these signals are used to control the small motors in electric hands, elbows, wrist rotators, and other similar equipment. The less-familiar switch-based and proportional position-sensing controls are also explained. A complete listing of the major suppliers and products available will aid in understanding a discussion of the criteria for using external power instead of, or along with, body power to control and activate prosthetic function.
肌电传感器（用于检测记录为肌电图的信号的电极和处理器）是控制电动上肢假肢最重要的人机接口。本文对肌电信号采集进行了简单解释，然后讨论了如何利用这些信号来控制电动假手、肘部、腕部旋转器及其他类似设备中的小型电机。还解释了不太为人熟悉的基于开关和比例位置传感的控制方式。主要供应商和现有产品的完整列表将有助于理解关于使用外部动力而非身体动力或两者结合来控制和激活假肢功能的标准的讨论。
