This enables monolithically integrated optoelectronic applications based on standard silicon. One possibility of implementation are emitting and sensing elements nested into each other in array structures, which together form a so-called Bidirectional Microdisplay, i.e. an element that displays an image and acts as a camera at the same time.
Such a component will lead to new generation of personalized information systems that on one hand provide visual information to the user and on the other hand are sensitive to visual interaction. Using some sort of modified eyeglasses the user will perceive her or his environment the usual way, additional optical information will be provided using the information system (Augmented Reality).
This information may be adapted to the overall context, both unconsciously and by intent. Without using the hands or spoken commands the user can control the presented information just with movement or actions of the eyes. At SID 2008, Fraunhofer IPMS will present a respective demonstrator for the first time, which clearly shows the future possibilities of this technology.

Cells need to repair damaged DNA in our genes to prevent the development of cancer and other diseases. Our cells therefore activate and send “repair-proteins”...
The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...
Nature does amazing things with limited design materials. Grass, for example, can support its own weight, resist strong wind loads, and recover after being...
Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
