Professor Peter Hofmann and his team at the Competence Center Electrical and Electronic (EE) Architecture at the Technische Universität Dresden (TU Dresden) have successfully developed the first self-organizing electronic components. These so called autonomous units form the basis for complex technical systems of the future. For this purpose, the scientists have adopted the knowledge of complex systems found in nature.
Organisms are structured according to the modular assembly concept – cells form tissue, tissue forms organs and these in turn form the organism. If individual cells die off, then the organism continues to function. This is because although the cells interact with their neighbouring cells, each individual cell is autonomous in its function. If necessary, it is even possible for other cells to step into the breach and take on a replacement function.
Engineers have been astonished about how effortlessly natural systems seem to adapt to new situations. As an example, a population of ants always finds the shortest way between food site and anthill without possessing a central instructional order. The mechanisms which take place in the human organism are equally fascinating, regarding for example injured skin cells or even entire organs which can regenerate themselves following an accident.

There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Jülich scientists have now introduced a new concept that allows currents up to ten times greater during charging and discharging than previously described in the literature. The improvement was achieved by a “clever” choice of materials with a focus on consistently good compatibility. All components were made from phosphate compounds, which are well matched both chemically and mechanically.
The low current is considered one of the biggest hurdles in the development of solid-state batteries. It is the reason why the batteries take a relatively long...
