    Argus II Retina Implanted with Success

    The Argus II system is a retinal implant device developed by Second Sight Medical. The device uses a camera mounted on special glasses that sends a signal to an electronic receiver with 60 electrodes implanted inside the eye....
  • The flexible sensor could be integrated into low-cost sensing systems for in-line diagnostics and monitoring

    Multispectral Light Sensors Built from Doped Nanorods

    Semiconductor-based photodiodes are widely used in industry to detect light at a range of frequencies from the ultraviolet through the visible to the near infra red. Such photodiodes operate by absorbing photons, which then generate a flow of...
  • Professor Zenghu Chang from the Department of Physics and the College of Optics and Photonics at the University of Central Florida set a world record when he produced an attosecond pulse just 67as in duration

    Lasers Freeze Electron Movement

    Massachusetts Institute of Technology (MIT) professor Harold Edgerton is widely known as a pioneer in the field of ultra-high speed photography. By synchronizing strobe flashes with the motion of objects, then taking a series of photographs through...
  • IMEC researchers have found that illumination stabilizes the morphology of polymerfullerene bulk heterojunction BHJ solar cells that are exposed to elevated temperatures

    Light-Induced Stabilisation of Organic Solar Cells

    Organic solar is a topic of much interest because of their light weight, flexibility and low manufacturing costs. At IMOMEC, Imec’s associated lab at Hasselt University in Belgium, researchers have found that illumination stabilizes the...
  • Fraunhofer researchers have developed a technique to produce mini-OLED screens without colour filters

    OLED Production Technique Slashes Costs, Improves Luminosity

    Screens made of organic light-emitting diodes (OLEDs) are a promising technology. Until now, however, a minimal lifespan and very high production costs have prevented them from becoming a widespread commercial product. Researchers at the Fraunhofer...
