华盛顿D。C:一组研究人员想出了世界最快的可伸缩、集成电路可以产生新一波的可穿戴电子产品。
由大学麦迪逊分校的工程师,电路是一种进步,推动物联网和更多的连接,高速无线世界。
的推进是一个平台制造商寻求扩大可穿戴电子产品的功能和应用程序,包括那些与生物医学应用程序,尤其是当他们努力发展设备利用新一代的无线宽带技术称为5克。
与波长尺寸毫米和米,微波无线电频率的使用频率的电磁波。3兆赫到300兆赫范围。直接落在5克。
在移动通信、微波无线电频率的5 g网络将容纳越来越多的手机用户,显著提高数据传输速度和覆盖区域。
在重症监护室,表皮电子系统(电子,坚持皮肤像临时纹身)可以允许健康保健人员远程监控病人和无线,增加病人舒适,减少传统的电缆和电线。
让新的、可伸缩的集成电路如此强大是他们独特的结构,灵感来自电话双绞线电缆。事实上它们包含,从本质上讲,两个缠绕在重复S-curves输电线路。
这蜿蜒的形状,形成两层分段金属块,像一个3 d拼图,给出了输电线路延伸的能力而不影响他们的表现。它还有助于保护线路不受外界干扰,同时,限制电磁波流经,几乎完全消除目前的损失。目前,研究者的可伸缩的集成电路可以在无线电频率水平40兆赫。
,不像其他的可伸缩的输电线路的宽度可以达到640微米(或.64点毫米),研究者的新柔性集成电路只是25微米(或.025毫米)厚。足够小的在表皮电子系统是非常有效的,在许多其他应用程序。
团队领导Zhenqiang“杰克”马说,“我们已经找到一种方法将高频有源晶体管集成到一个有用的电路,可以无线。这是一个平台。这将打开大门大量的新功能。”
这项研究发表在《先进功能材料》杂志上。
WASHINGTON D.C: A team of researchers has come up with the world<\/a>'s fastest stretchable, integrated circuits that could yield a new wave of wearable<\/a> electronics.<\/p> Created by University of Wisconsin-Madison engineers, the circuits are an advance that could drive the Internet of Things and a much more connected, high-speed wireless world.<\/p> The advance is a platform for manufacturers seeking to expand the capabilities and applications of wearable electronics, including those with biomedical applications, particularly as they strive to develop devices<\/a> that take advantage of a new generation of wireless broadband technologies referred to as 5G.<\/p> With wavelength sizes between a millimeter and a meter, microwave radio frequencies are electromagnetic waves that use frequencies in the .3 gigahertz to 300 gigahertz range. That falls directly in the 5G range.<\/p> In mobile communications, the wide microwave radio frequencies of 5G networks will accommodate a growing number of cellphone users and notable increases in data speeds and coverage areas.<\/p> In an intensive care unit, epidermal electronic systems (electronics that adhere to the skin like temporary tattoos) could allow health<\/a> care staff to monitor patients remotely and wirelessly, increasing patient comfort by decreasing the customary tangle of cables and wires.<\/p> What makes the new, stretchable integrated circuits so powerful is their unique structure, inspired by twisted-pair telephone cables. They contain, essentially, two ultra-tiny intertwining power transmission lines in repeating S-curves.<\/p> This serpentine shape, formed in two layers with segmented metal blocks, like a 3-D puzzle, gives the transmission lines the ability to stretch without affecting their performance. It also helps shield the lines from outside interference and, at the same time, confine the electromagnetic waves flowing through them, almost completely eliminating current loss. Currently, the researchers' stretchable integrated circuits can operate at radio frequency levels up to 40 gigahertz.<\/p> And, unlike other stretchable transmission lines, whose widths can approach 640 micrometers (or .64 millimeters), the researchers' new stretchable integrated circuits are just 25 micrometers (or .025 millimeters) thick. That's tiny enough to be highly effective in epidermal electronic systems, among many other applications.<\/p> Team lead Zhenqiang \"Jack\" Ma said, \"We've found a way to integrate high-frequency active transistors into a useful circuit that can be wireless. This is a platform. This opens the door to lots of new capabilities.\"<\/p> The study appears in the journal Advanced Functional Materials.<\/p> <\/div><\/div>
