摘　　要：肌阻抗图是一种评估肌肉状态的新方法,本文尝试将这种新方法应用于穿戴式肌肉疲劳的实时监测。为了进一步提高肌阻抗图测量肌肉疲劳状态的准确度,优化现有电极配置,使得电极尺寸既紧凑又有足够的电位灵敏度,本文提出一种新的电极配置方案:将两对电极沿z轴并行排列;利用人体阻抗分析仪对肱二头肌展开静息状态肌肉电阻抗和肌肉疲劳测试实验。实验结果表明,电极配置的并行排列方式比串行排列具有更高的测量准确度,为电极配置方法提供了新思路。Electrical impedance myography(EIM)is a novel method for assessing muscle state,this paper attempt to apply EIM to real-time monitor the degree of wearable muscle fatigue.In order to further improve the accuracy of EIM in measuring muscle fatigue state,optimizing the existing electrode configuration to make the array more compact and have sufficient potential sensitivity.This paper proposes a novel electrode configuration scheme,in which two pairs of electrodes are arranged in symmetric along the z-axis;the static experiment and muscle fatigue moving experiment have been carried out on the distribution of electric current in the biceps of the humerus by means of ImpTM SFB7.The experimental results show that the electrode configuration with parallel arrangement has higher measurement accuracy than the serial arrangement,which will provide a new idea for the electrode configuration of EIM.
