摘要:
柔性电极因其穿戴式表面肌电采集的优势而得到研究学者的广泛关注，但很少有研究针对柔性电极的设计参数提 供明确的指导和规范。本实验首先对可能影响电极性能的参数进行了分析；然后利用柔性印刷工艺与喷墨印刷工艺制作 5种不同规格的柔性干电极，并将其与商用湿电极进行对比，设计基于尺侧腕伸肌的肌电采集实验，得到100个表面肌电 信号段；最后对信号段的时频域特性进行分析，从而确定相关参数对电极性能的影响。结果表明增加电极高度后的有源 柔性印刷电路板电极具有更好的信号采集性能。
Abstract:
Abstract: Flexible electrode has received wide attention from researchers because of its advantages in wearable surface electromyography signal acquisition. However, few studies have provided clear guidance and specifications for the design parameters of flexible electrode. Herein the parameters that may affect the performance of the electrode are analyzed. Five kinds of flexible dry electrodes of different specifications fabricated by flexible printing process and inkjet printing process are compared with the commercial wet electrode. The electromyography signal acquisition experimentation based on ulnar wrist extensors is designed to obtain 100 surface electromyography signal segments. Finally, the time-frequency domain characteristics of the signal segment are analyzed, thereby determining the effect of the relevant parameters on the electrode performance. The results show that the active flexible printed circuit board electrodes after increasing the electrode height have a better signal acquisition performance.
