LG unveiled the "world’s first flexible OLED panel for smartphones" on Monday morning and bragged about how products with "enhanced performance and differentiated designs" would follow next year. A fully flexible smartphone is probably not going to be among those exciting new things, however.

Futurists are always talking about how flexible electronics will change our lives in amazing ways, but we’ve yet to see anything mind-blowing come to market. A team of scientists from the University of Texas in Austin, however, think they’ve found the key to changing that: ultrafast graphene transistors printed on flexible plastic.

As often as we’ve seen flexible electronics, there haven’t been many examples that could stretch — a definite problem for wearables as well as any gadget that could afford to take a pull or squeeze. North Carolina State University’s Yong Zhu and Feng Xu may have covered this gap through a form of silver nanowire conductor that keeps the energy flowing, even if the wire is stretched as much as 50 percent beyond its original length. By coating the nanowires with a polymer that traps the silver when solid, the researchers create an elastic material that can crumple and let the nanowire take the strain without interruption. Although the stretchy conductor’s nature as a research project could put any practical use years into the future, Zhu notes that it can take loads of abuse, making it a perfect fit for rugged mobile devices. It should also allow for robots with a gentler touch and a more natural look… although we’ll admit we’re skittish about the creepy androids likely to follow.
