2017年5月10日,国际学术权威刊物自然出版集团旗下子刊《Scientific Reports》杂志在线发表了瑞士洛桑联邦理工学院S. Micera研究员的一篇研究论文,研究描述了一种能帮助人们在意外滑倒后迅速恢复平衡的机械外骨骼。研究人员表示,这一新型可穿戴设备能够用于协助老人、残疾人等行动不便的人士,以防他们摔倒。


S. Micera及其同事研发的这种可穿戴机器名为活动性骨盆固定器(APO)。该机器利用特定算法,能迅速检测出穿戴者是否失去平衡,并在臀部产生一个抵消扭矩,以协助穿戴者平衡恢复。




An ecologically-controlled exoskeleton can improve balance recovery after slippage


The evolution to bipedalism forced humans to develop suitable strategies for dynamically controlling their balance, ensuring stability, and preventing falling. The natural aging process and traumatic events such as lower-limb loss can alter the human ability to control stability significantly increasing the risk of fall and reducing the overall autonomy. Accordingly, there is an urgent need, from both end-users and society, for novel solutions that can counteract the lack of balance, thus preventing falls among older and fragile citizens. In this study, we show a novel ecological approach relying on a wearable robotic device (the Active Pelvis Orthosis, APO) aimed at facilitating balance recovery after unexpected slippages. Specifically, if the APO detects signs of balance loss, then it supplies counteracting torques at the hips to assist balance recovery. Experimental tests conducted on eight elderly persons and two transfemoral amputees revealed that stability against falls improved due to the “assisting when needed” behavior of the APO. Interestingly, our approach required a very limited personalization for each subject, and this makes it promising for real-life applications. Our findings demonstrate the potential of closed-loop controlled wearable robots to assist elderly and disabled subjects and to improve their quality of life.
