When a limb is amputated, the surgeon connects these opposing muscles within the residuum to create an AMI.
當肢體被截掉以后，外科醫(yī)生把殘肢內(nèi)這些拮抗肌連接起來，形成AMI。
Now, multiple AMI constructs can be created for the control and sensation of multiple prosthetic joints.
現(xiàn)在，可以創(chuàng)建多個AMI結(jié)構(gòu)用于多個人工關(guān)節(jié)的控制和感知。
Artificial electrodes are then placed on each AMI muscle,
然后，將人造電極放在每塊AMI肌肉上，
and small computers within the bionic limb decode those signals to control powerful motors on the bionic limb.
仿生肢體內(nèi)的小計算機對這些信號解碼，以控制仿生肢上的強力馬達。
When the bionic limb moves, the AMI muscles move back and forth, sending signals through the nerve to the brain,
當仿生肢體移動時，AMI上的肌肉來回移動，通過神經(jīng)向大腦發(fā)送信號，
enabling a person wearing the prosthesis to experience natural sensations of positions and movements of the prosthesis.
使佩戴假肢的人能體驗到假肢的位置和運動的自然感覺。
Can these tissue-design principles be used in an actual human being?
這些組織設計原則能用于真正的人體嗎？
A few years ago, my good friend Jim Ewing -- of 34 years -- reached out to me for help.
幾年前，我34歲的好朋友吉姆·尤文向我求助。
Jim was in an a terrible climbing accident.
吉姆經(jīng)歷一了次可怕的登山事故。
He fell 50 feet in the Cayman Islands when his rope failed to catch him hitting the ground's surface.
在開曼群島上，他下跌了50英尺，他的繩子沒能接住他，導致他直接撞到地上。
He suffered many, many injuries: punctured lungs and many broken bones.
他身上多處受傷，肺被刺穿、許多骨頭都斷了。
After his accident, he dreamed of returning to his chosen sport of mountain climbing, but how might this be possible?
事故之后，他依然夢想著回到自己選擇的登山運動眾，但這怎么可能呢？
