近期，由新加坡A.STAR微电子研究所开发的“神经元阵列芯片”，这种芯片可以植入人的大脑实现长期颅内停留并且不会损坏其他脑组织。芯片的底部由很多微型的探针阵列组成，这些探针可以与大脑中的神经连接并接收肢体控制讯号，这种技术研究成熟以后将可以帮助截肢者和患有脊髓炎的患者利用大脑来控制机械假肢行走。虽然上面说的给你感觉这玩意儿相当厉害，一定能够帮助不少原本无法行走的人们，好处多多。但像大脑这样精密的组

近期，由新加坡A.STAR微电子研究所开发的“神经元阵列芯片”，这种芯片可以植入人的大脑实现长期颅内停留并且不会损坏其他脑组织。芯片的底部由很多微型的探针阵列组成，这些探针可以与大脑中的神经连接并接收肢体控制讯号，这种技术研究成熟以后将可以帮助截肢者和患有脊髓炎的患者利用大脑来控制机械假肢行走。

虽然上面说的给你感觉这玩意儿相当厉害，一定能够帮助不少原本无法行走的人们，好处多多。但像大脑这样精密的组织要想成功的把这玩意儿植入进去而不出现任何差错，这还是需要进行深入研究的。我们目前常用的小损伤手术方法是通过颅骨钻孔来建立一个“通道”然后连接所需要的设备。这种方法并不完美，如果出现问题，患者可能会引发感染甚至颅内出血。所以科学家们想为此设计一套全新的解决方案。

为了解决上面说到的问题，A.STRA团队首先将芯片做的尽可能的薄，另外他们采用一种创新式的微组装技术（以微米为单位）可以将芯片送到到大脑蛛网膜下腔内，然后进行进一步的操作。目前研究小组还在完善手术实施的过程并开始测试芯片与人体组织的相容性，再有一段时间的努力，这种芯片将有可能成功运用到现代医疗技术当中来。
