Abstract：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.
