This Computer Chip Will Self-Destruct in 5 Seconds

The new method uses silicon computer wafers attached to a piece of tempered glass that shatters into smithereens when heated in one spot. The heat can be turned on via a remote, which in the future could conceivably be triggered by anything from Wi-Fi to a radiofrequency signal, said Gregory Whiting, a materials scientist and manager of the Novel Electronics Group that produced the chip at PARC, a Xerox company.
