摘　　要：现在,高密度表面肌电信号的采集与分析已成为人-机交互接口领域的前沿研究方向。而在如何兼顾采集系统采集信号的高质量和系统自身的便携性的问题却亟需解决。文中通过对系统的多层次、模块化设计,完成一款高性能的模块化高密度表面肌电采集系统。其支持4 kHz采样频率、支持24位数据精度,支持256通道数据的同步采集。在有与同类商用设备可比的技术参数的同时,该设备质量约为450 g,具有良好的便携性。Recently, the acquisition and analysis of high-density surface electromyography(HD-sEMG) has become the front research direction in the field of human-machine interface. However, there is an inevitable problem of the design of its acquisition system we have to face, that is how to balance the contradiction between high-performance and portability of the system. In this paper, we solve this problem by multi-level and modular design of the system.he system in this paper is a HD-sEMG acquisition system of with high standard. It consists of a high-performance modular HD-sEMG acquisition device and a multifunctional cross-platform software. This system can collect 256-channel HD-sEMG signal simultaneously. Meanwhile, it supports collecting signal at 4 ksps and 24-bit resolution. Furthermore, this system weighs about 450 grams, which makes it portable.
