[交流] 吃进去的是石墨吐出来的是电路：剑桥大学研发出喷墨打印机打印电路技术已有3人参与

Yes, graphene is amazing and possesses many useful / otherworldly properties. The ability to use graphene itself to print flexible, transparent thin-film transistors via an inkjet printer is just another one of them. Over at the University of Cambridge, researchers have discovered that it's possible to print standard CMOS transistors using a graphene component. Provided the graphene is chipped off a block of graphite using a chemical solvent and the larger (potentially print-head blocking) chips are removed, it can be turned into a polymer ink which can then run through a conventional inkjet printer. The potential result of this is flexible, transparent and wearable computer circuitry coming from ordinary printers as opposed to several multi-million-dollar machines in a factory, which has long been the historical standard. Besides, who wouldn't want to print their own circuitry on a PhotoSmart MFP rather than whatever report might be due the next day?

近年，被称作能够“影响未来的八大科技”之一的3D打印技术也逐渐流行起来。无论是此前“吃进去的是沙子，吐出来的是艺术”的太阳能3D打印机，还是能“让你把想像力打印出来”的3D打印机，越来越多的3D打印技术逐渐成熟，并呈现在用户面前。现在，电路也可能使用喷墨打印机打印出来！

用作打印电路的是一种被称作“石墨烯”的材料。石墨烯具备很广泛的用途与超凡的属性。来自剑桥大学的研究人员发现，仅需要使用电脑喷墨打印机，再利用石墨烯本身的特性，就能打印出透明薄膜晶体管。同时他们还认为，利用石墨烯材料也可能打印出标准CMOS晶体管。

在使用化学溶剂从石墨块中获得石墨烯后，再去除可能堵塞打印头的较大碎屑，就得到一种可供喷墨打印机使用的混合油墨。这种油墨使得该项技术的应用变得非常方便灵活。仅使用普通的打印机就能制造出透明耐用的计算电路，而不需要使用工厂里动辄数百万美元的专业设备。

你认为这项技术怎么样呢？
