Scanning electron microscope image of an array of optomechanical accelerometer devices formed in the surface of a silicon microchip. Highlighted green areas represent proof masses which are suspended by nanoscale tethers across the open etched areas of the chip. Even smaller, and barely visible, are pink highlighted optical cavities which sensitively read out the motion of the proof masses. (Credit: Martin Winger)

TechAndComputer (Oct. 17, 2012) — Imagine navigating through a grocery store with your cell phone. As you turn down the bread aisle, ads and coupons for hot dog buns and English muffins pop up on your screen. The electronics industry would like to make such personal navigators a reality, but, to do so...

Revolutionary ultrathin, flat lens: Smartphones as thin as a credit card?

  • PDF
Scientists are reporting development of a revolutionary new lens -- flat, distortion-free, so small that more than 1,500 would fit across the width of a human hair -- capable in the future of replacing lenses in applications ranging from cell phones to cameras to fiber-optic communication systems. The advance could lead to smart phones as thin as a credit card. (Credit: © bloomua / Fotolia)

Semiconductors grown on graphene could fundamentally change semiconductor industry

  • PDF
TechAndComputer (Sep. 10, 2012) — Researchers at the Norwegian University of Science and Technology (NTNU) have patented and are commercializing GaAs nanowires grown on graphene, a hybrid material with competitive properties. Semiconductors grown on graphene are expected to become the basis for new types of device systems, and could fundamentally change the semiconductor industry. The technology underpinning their approach has recently been described in a publication in the American...
