A research group led by Academy Professor Mikko Sams is developing a brain-computer interface, a device that transforms electrical or magnetic brain signals into commands a computer can understand. Equipment of this kind is necessary. For instance, it enables physically disabled persons to use a computer keyboard. The Brain-Computer Interface, or BCI, allows both physically disabled and healthy persons to direct a computer by merely thinking of certain commands. The On-line Adaptive Brain-Computer Interface project which develops these interfaces is part of the Proactive Computing Research Programme (PROACT), which is funded by the Academy of Finland.
The Brain-Computer Interface is based on mental activity. When a person thinks about performing a particular task such as raising a finger, this gives rise to brain activity that can be measured through the scalp via electronic sensors called electrodes. Different mental tasks create different brain signals. The BCI being developed in Sams’ group relies specifically on the analysis of brain signals created by the movement of a finger. Measured signals do, however, contain background noise. The challenge is to identify those particular signal characteristics that relate to the movement of a single finger.
Development of the BCI improves understanding of signals created by the brain during different tasks. It also enables the development of mathematical methods used to decipher the tasks. The project is carried out in co-operation with the Käpylä Rehabilitation Centre and the Invalid Foundation in Finland to benefit quadriplegics.

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...

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...
