Basically, DARPA is looking into sensors and other “sophisticated electronic microsystems” which will have their place in a warzone, and will self-destruct after a while, so that opposing forces who pick them up cannot apply the techniques of reverse engineering and come up with formidable weapons of their own. How about a smartphone that self-destructs after you lose it, simply because you sent activated a “kill switch” remotely? That would be cool, and the thief who took your smartphone might actually see his or her pants catch fire as it melts. I want in on such tech, how about you?
