【间谍新玩意:能自动解体成碎片的芯片】施乐帕洛阿尔托研究中心研发了一种遇热自动解体成碎片的芯片,这种(DUST)压力启动自动解体技术使得这款看起来很普通的芯片可以通过遥控,芯片上的小电阻器将加热,芯片将会碎成无数肉眼见不到的小碎片,看起来就像什么也没发生过。研究者表示毫无疑问,这款技术将能用在信息安全、间谍跟踪、科学探测、海洋探寻等领域,例如将无数芯片布置在环境中用来预测天气、预警地表震动,然后不需要人为足迹干预就能将其移除,对环境不造成影响。专家表示,这是对于物联网发展的新探索——如何更有效地感知和控制物理世界。
James Bond's next computer? US Military bosses reveals chip that can blow itself up on command to keep secrets safe
Chip technology developed with PARC, a Xerox company
Project called DUST, or Disintegration Upon Stress-Release Trigger

It is undoubtedly the computer chip James Bond would use.
Military researchers have shown off a self destructing chip they say could be used in everything from spy gadgets to remote sensors.
It works like a normal chip - but can disintegrated on command, leaving only tiny fragments that are invisible to the human eye.

The glass can then bestressed to breaking point by heat.
When a circuit is switched on, a small resistor heats up.
This causes the glass chip to shatter.
'DUST, or Disintegration Upon Stress-Release Trigger, is a technology that allows electronic devices using full-performance microchips to be disintegrated on command, leaving only tiny fragments that are invisible to the human eye,' said DARPA.
'The DUST technology builds on PARC's cutting-edge capabilities in advanced manufacturing, novel electronics, and smart devices.'
The secretive research was shown off at DARPA's Wait, What? event in St. Louis on Thursday, according to IDG News.
'The applications we are interested in are data security and things like that,' said Gregory Whiting, a senior scientist at PARC in Palo Alto, California.
'We take the glass and we ion-exchange temper it to build in stress,' said Whiting.

'What you get is glass that, because it's heavily stressed, breaks it fragments into tiny little pieces.'
In a demonstration on Thursday, the glass was stressed to breaking point by heat. When a circuit was switched on, a small resistor heated up and the glass shattered into thousands of pieces.
Even after it broke up, stress remained in the fragments and they continued breaking into even smaller pieces for tens of seconds afterwards.
The chip forms part of a bigger project called Vanishing Programmable Resources (VAPR) program, designed to 'demonstrate electronic systems capable of physically disappearing in a controlled, trigger-able manner.'
These transient electronics should have performance comparable to commercial-off-the-shelf electronics, but with limited device persistence that can be programmed, adjusted in real time, triggered, and/or be sensitive to the deployment environment, DARPA says.

In addition to military applications, PARC is exploring a wide range of commercial and scientific uses for the DUST technology.
One possibility is to help protect personal information such as laptops, mobile phones, e-wallets, and wearables – giving consumers and enterprises peace of mind that their data won't be copied or exploited.
The movie industry could also potentially use PARC's DUST technology to protect highly valuable content it produces and distributes every year.
In the world of environmental science, DUST sensors could be distributed in large numbers to help measure wide-area phenomenon like weather patterns for hurricane prediction or subtle vibrations that precede earthquakes, and then be effectively removed from the environment with no residual footprint.
'Imagine being able to cover a large area, like the ocean floor, with billions of tiny sensors to 'hear' what is happening within the earth's crust, and have them quickly disintegrate into, essentially, sand, leaving no trace and not harming the planet or sea life,' said Sean Garner, PARC researcher and principal investigator on the DUST project.
'I'm looking forward to working with other scientists and companies that can help us explore cool new ways to deploy DUST that we may not have even considered.'
'This research at PARC is part of our efforts to develop the Internet of Everything – building the technology fabric that lets us sense and manipulate the physical world in the same way that we've grown accustomed to interacting with information,' said Stephen Hoover, CEO of PARC.
'We're also focused on new technologies, both hardware and software, to help us protect information as our 'digital selves' take on more and more importance in our lives.'
