　　Electronics With A Twist

电子产品也能折叠英语美文

　　Electronics come in all shapes and sizes—but there’s been a limit on their flexibility. Now, researchers say they’ve created electronics that can be shaped in virtually any way, including bent, stretched and even tightly coiled. They published their results in the Proceedings of the National Academy of Sciences.

　　Silicon is the principal ingredient in electronics, and it’s inflexible and brittle. To overcome this constraint, the researchers first developed one-dimensional, single-crystal silicon electronics, which they reported in 2005. The crystals could be stretched without losing their properties.

　　Then last summer they demonstrated that they could build tiny circuits that were connected by tiny metal bridges. The final product could be bent and placed over a curved surface. Most recently, the researchers modified the bridges into an S shape. The additional step takes the flexibility further—the electronics can now be twisted into curves as well. One use could be a sensor on a human body. But the scientists see applications beyond the biological—they’re trying to develop flexible solar cells. Flat cells need to move to follow the sun. But a flexible cell could always receive direct rays without constant repositioning.

　　可折叠的电子产品

　　电子产品的形状和大小多种多样---但是它们的一个弱点就是不具有可塑性。现在，研究人员们称他们已经开发出了新的电子产品，这些电子产品可以被任意加工，比如可以弯曲、伸展甚至紧紧地缠绕起来。研究人员在美国科学院院刊上《Proceedings of the National Academy of Sciences》发表了他们的研究结果。

　　硅是电子产品的主要组成部分，但是它不具有可塑性而且易碎。为了克服这个限制，研究人员们首先开发了一维单晶硅电子产品。这项研究在2005年被报道。这些晶体可以被伸展，同时又不失去特们的性质。

　　今年夏天研究人员展示的结果表明：他们能构建非常小的由细微的金属桥连接而成的电路。最终的产品可以弯曲并置放在曲面上。最近，这些研究人员把金属连接桥改进成S形状。这进一步提高了可塑性---这些电子产品现在同样可以被扭曲成曲线。这些电子产品的一个用途可能是做为人体传感器。但是，科学家们认为它们的应用不仅仅局限于生物领域----他们正试图研发可折叠太阳能电池板。使用平板太阳能电池的时候需要随着太阳的`移动来移动电池板，但是可折叠太阳能电池板就能一直接受太阳的直射，从而无需调整太阳能电池板的位置了。
