摘要：
This paper proposes a passively-powered knee exoskeleton (PPKE) to provide power assistance during squat lifting of objects from the ground. The passive powering mechanism is designed to capture 20% of the waste mechanical energy available at the biological knee joint during decent phase and to release the stored energy in ascending phase in a complete squatting cycle. The effectiveness of proposed system was verified by experiments using surface electromyography (sEMG) signals under different test conditions. PPKE reduced the peak root-mean-square averages of sEMG signals of knee extensor muscles by 15% during squatting.
