Repair shop ready to close: the new magnetic ink to make equipment self fix-IT information
Beijing time on November 4, according to foreign media reports, the United States University of California, San Diego, a team of researchers has developed a magnetic ink particles, when cracks were found on the equipment can repair itself. Cracks have appeared, use the ink "print" sensor can be connected together by magnetic force, automatically when the device for damage signs to repair it.
Amai·banduojia team member (Amay Bandodkar) said in an interview with the New York Times, "like human skin with scalability and self-healing capabilities, we want to make printouts of the electronic device has the ability to repair itself. ”
The focus of this study is to develop with the fiber "together" of the sensor, the development of smart clothing can repair within 50 milliseconds up to 3 mm long crack. In the demo video, lit a small light bulb sensor is cut in two, small light bulbs went out, within a few seconds, magnetic sensors that were cut in two, "healing" together, small bulbs lit up again.
In order to have a healing effect, the research team used a common powder of neodymium magnetic material in the refrigerator and the hard drive and put it into the ink, which helps researchers avoid time-consuming for several hours of chemicals and heating technology.
More estimates, $10 worth of ink can make "hundreds of smaller devices," used the ink to make the devices can help reduce waste, because even if the device appears damaged, users do not have to throw them away, "because the device will be able to repair itself within a few seconds, users can continue to use it."
Current research team is testing a different ratio of the best ink to print products, the goal is to use the ink to produce all kinds of products, from solar panels to medical devices. This technology may soon be used in the production of everyday electronic products when users no longer have maintenance staff to help replace parts.
维修铺准备关门：新型磁性墨水可让设备自我修复 - IT资讯
北京时间11月4日消息，据外媒报道，美国加州大学圣迭哥分校一个研究团队开发出了磁性墨水微粒，当设备出现裂缝后能自行修复。有裂缝出现后，利用这种墨水“打印”的传感器能通过磁力相互连接在一起，在设备出现损坏苗头时自动对它进行修复。
研究团队成员阿迈·班多加(Amay Bandodkar)在接受《纽约时报》采访时表示，“就像人类皮肤具有可伸缩性和自我愈合能力一样，我们希望使打印出来的电子设备具有自我修复能力。”
这项研究的重点是开发能与纤维“融合在一起”的传感器，开发的智能服装能在50毫秒内修复至多3毫米长的裂缝。在一段演示视频中，用于点亮一个小灯泡的传感器被剪为两段，小灯泡熄灭，数秒钟内，磁性使被剪为两段的传感器“愈合”在一起，小灯泡重新亮了起来。
为了产生自愈合效应，研究团队利用了在冰箱和硬盘中常见的粉状钕磁性材料，并把它制作成墨水，这有助于研究人员避免使用耗时达数小时之久的化学和加热工艺。
班多加估计，价值10美元的这种墨水能制造“数百个小型设备”，用这种墨水制造的设备有助于减少浪费，因为即使设备出现损坏，用户也不必扔掉它们，“由于设备在数秒钟内就能自我修复，用户就可以继续使用了”。
目前研究团队正在测试不同打印产品的最佳墨水配比，目标是利用这种墨水生产从太阳能电池到医疗器械在内的各类产品。这一技术可能很快用于生产日常电子产品中，届时用户就再也不用请维修人员帮忙更换零部件了。
