Apple patent reveals carbon nanotubes could give iPhones the bends

Flip phones may have died out with MySpace, but if technology in a patent awarded to Apple this week eventuates into a commercial product, a future version of the iPhone may just bring them back. The document describes a system that uses carbon nanotubes for signal paths in a flexible printed circuit, which could form the basis of devices that can bend along a seam, even through the display itself, without damaging the circuits.
Flexible electronics, like the ReFlex, are beginning to show up in patents and prototypes in different forms. LG has been showing off its rollable OLED screens for a few years, and flexible circuitry could be made of “liquid metal” or everyone’s favorite wonder material, graphene.
