But the new polymer, designed by researchers from the Institute of Biomaterial Science at Germany’s Helmholtz Center, Geesthacht, is able to flip back and forth between two stages 250 times.Since they can change shape over and over, the polymers can drive motors. The Hemholtz center team demonstrated one, called a heat engine, in which a gear is turned as the temperature rises and falls. As the polymer mix is heated or cooled, some of the molecules inside crystallize and expand, while others start to flow and contract. That is what makes the movement and provides direction.
LG plans to launch a flexible OLED smartphone before the end of the year, the company’s VP of mobile has confirmed, though it’s unclear to what extent the work-in-progress handset will actually flex. The OLED panel in question is the handiwork of LG Display according to VP of LG mobile Yoon Bu-hyun, the WSJ reports, with the proposed device set to launch sometime in Q4. LG Display’s work on flexible OLEDs has been underway for some time, though the company’s efforts have perhaps been overshadowed somewhat by rival Samsung’s YOUM development. Last year, according to a Korea Times report, LG Display was preparing for
