一即使在这样一个充满分歧的时代,似乎还是有几件事我们可以达成共识:婴儿很可爱,踩到乐高玩具是最糟糕的经历,以及我们需要在设备上玩最新视频游戏的新方法。虽然第三点可能并不是那么普遍,可用于体内或是可穿戴的电子设备或对医疗行业或个人消费者均有帮助。为此,研究人员已发明了一种新的触摸面板,它出奇地灵活,且具备生物相容性。在拉伸时,这项新技术在电子结构上比目前的替代产品更稳定,同时这种材料不会随着时间的推移劳损。新面板的主要成分叫水凝胶,是一种充满水的聚合物网络,可以安全地用于人体内和体表,已知的应用范围从药物运输到为组织工程和伤口愈合创造支架。由于水凝胶主要是水,因此研究人员能够将离子分解入面板,允许电流自由地流动而过。当一只手指与其表面接触,它便建立了回路,面板各个角落的传感器记录下电流的变化,这之后可用于计算手指在表面的位置。正如研究人员今天在《科学》网络版上报告的那样,即使被拉伸到原始面积的十倍大,该面板依然保持工作,而如上面的视频所示,当它被塑形成环绕人类胳膊的样子时,它还可以被用来弹奏虚拟钢琴。该技术还远没有到完美的地步,它目前有些不精确,且材料的耐久性也是问题,所以你可能不会成为下一个肖邦,在水凝胶键盘上学习弹奏“一闪一闪亮晶晶”,但有一天我们能拥有可穿戴的柔性触控板的这一想法可能不会需要太久才能实现。

Stretchy touchpad allows you to play piano on your arm

原文摘要:

Even in these divisive times, there seem to be a few things we can all agree on: Babies are cute, stepping on a Lego is the worst, and we need new ways to play the latest video game on our gadgets. Although that third one may be a bit less universal, having electronics that can be used in and on our bodies could be useful for the medical industry and private consumers alike. To this end, researchers have created a new kind of touch panel that is both insanely flexible as well as biocompatible. The new technology is more electronically stable than current alternatives when stretched, and the materials don’t fatigue over time. The principle component of the new panel, hydrogel—a polymer network filled with water—is safe to use in and on the human body, having already found use in applications ranging from drug delivery to creating scaffolds for tissue engineering and wound healing. Because hydrogels are mostly water, the researchers were able to dissolve ions into the panel, permitting electricity to flow freely across it. When a finger makes contact with the surface, it grounds the circuit and sensors in each corner of the panel record the changes in current, which can then be used to calculate the location of the finger on the surface. As the researchers report online today in Science, the panel keeps working even when stretched 10 times its original area, and, as the video above shows, it can be used to play a virtual piano while molded around a human arm. The technology is far from perfected—it’s currently somewhat imprecise and there are questions about the material's durability over time—so you probably won’t become the next Chopin learning “Twinkle Twinkle Little Star” on the hydrogel keyboard, but the idea of one day having a flexible trackpad attached to our bodies might not be such a—wait for it—stretch.
