Next-gen smartphones could have sensors built into display glass (GizMag)

Corning, the company behind Gorilla Glass, radiation shielding glass, and hyperspectral imaging, has been working with Polytechnique Montreal to etch photonic circuits directly into the surface of Gorilla Glass. These circuits can then be used as sensors to detect light and temperature changes. Eventually, the technology could be used to take a temperature, read fingerprints, or conceivably even take pictures, although that kind of application is probably a long way off yet.

The future is very cool and very creepy. Who needs security cameras when we can watch you through any glass surface?
