Using Surface Electromyography to Analyze the Assistive Force Produced by Wearable Assistive Robot

Abstract

This paper proposed a method for using the integration of surface electromyography (iSEMG) signals to compute the assistive force produced by wearable assistive robot (WAR). A study was conducted to analyze a subject during lifting his leg tied with different weights. The iSEMG of vastus lateralis (VL) muscle was computed. Then the linear correlation between muscle force and iSEMG was obtained. Finally, the assistive force produced by WAR could be computed by the linear correlation with iSEMG. We find that the effect of assistive force produced by WAR can be clearly analyzed by iSEMG.
