To address these challenges, we propose an innovative lower-limb exosuit that integrates both passive and active components, designed to optimize lifting performance while ensuring user comfort and safety. This study evaluates the exosuit's effectiveness in reducing muscle activation and altering the range of motion during squat lifting tasks. Our exosuit leverages a spherical scissor linkage mechanism and elastic bands for hip support, and extension springs for knee support. Experimental evaluation using electromyography (EMG) and motion capture data reveals significant reductions in muscle activity for the rectus femoris and gluteus medius, particularly in the latter, with reductions of 34.6% and 63.2%, respectively. Additionally, substantial changes in joint flexion angles, especially at the ankle were ob. These findings highlight the exosuit's potential to mitigate physical strain and enhance lifting efficiency, paving the way for advancements in assistive technologies for lifting assistance.false[SDGs]SDG7conference paper10.1109/ARIS62416.2024.106799982-s2.0-85206269076
