“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 really wanted to come up with a system that was very rapid and compatible with commercial electronics.”
The result is a chip based on Gorilla Glass, the Corning-produced tough glass used in the displays of numerous smartphones.
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.
