10个可替换的人体器官

芝加哥大学的一个研究小组制造了一种能够向大脑传递信号的假手来解决这个问题。他们以猴子为测试对象，研究动物大脑对触摸信号的反应。当装备了可以刺激大脑的假手后，那些猴子的反应就好像他们身体接触到了物体一样。

Programming these same signals into artificial human limbs would give amputees replacement hands unlike anything we've developed before.

将这些类似的信号通过编程的方式写入造假肢，会给截肢者带来和以前研发出来的产品完全不同的假肢。

7.Thought-Controlled Bionic Legs

7.思想控制仿生腿

Though bionic legs are of course a huge boon to amputees, they lack actual nerve connections with the body. As a result, walking on them is cumbersome and tiring. But last year, Seattle resident Zac Vawter was outfitted with the world's first thought-controlled leg, a bionic limb that takes signals directly from his mind.

虽然仿生腿对截肢者来说是巨大的福音，但是它们与人体缺乏真正的神经联系，导致依靠仿生腿走路十分麻烦和劳累。但是去年，西雅图的居民Zac Vawter 安装了世界上第一支思想控制的腿，一种直接接受从他大脑发出信号的仿生肢体。

This technology previously existed for arms, but legs are rather more complicated. And since a misread signal can send you jumping off a bridge or in front of a moving car, thought-controlled legs need more stringent programming than equivalent arms. As one of the researchers delicately put it, “If you're using a bionic arm and it misbehaves, the elbow may move slightly. If the prosthetic leg misbehaves . . . that could be quite a safety issue.”
