Tungsten diselenide shows potential for ultrathin, flexible, semi-transparent solar cells

Graphene, the two-dimensional lattice of carbon atoms, may be the wonder material du jour, but ultrathin layers of other elements are also proving to be an exciting area of research. One-atom-thick sheets of germanium and tin have shown potential as semiconductors and a topological insulators respectively, and now ultrathin layers of tungsten and selenium have been used to create a diode that could be used in ultrathin, flexible, semi-transparent solar cells.

Stretchable optical circuits could find use in robot skin and more

If flexible electronic devices are ever going to become practical for real-world use, the circuitry incorporated into them will have to be tough and resilient. We're already seeing progress in that direction, including electrical wires that can still carry a current while being stretched. However, what if the application calls for the use of fiber optics? Well, scientists from Belgium may have that covered, too. They've created optical circuits utilizing what they believe are the world's first stretchable optical interconnections. Read More

LG challenges Samsung with the G Flex curved screen smartphone

It looks like LG and Samsung are at it again. Both companies were vying for our attention at CES 2013 with simultaneous "world's first" curved OLED television announcements. LG consistently led in the race to the consumer space, and looked liked being first to move the screen format onto smartphones with the announcement earlier this month of its plans to mass produce flexible OLED phone displays. Samsung had other ideas, however, and the Galaxy Round was launched just a few days later. LG has now caught up with the forthcoming release of its slightly larger G Flex smartphone, featuring a curved display that follows the contour of the face. Read More
