Ganz unterschiedliche Oberflächenstrukturen lassen sich mit Laserstrahlen herstellen.
In an Austrian-German research project, laser technology is being used to produce microscopic structures on electrical plugs in order to increase fail safety. Everyone has probably had a problem with loose contacts at some point. Electronic equipment malfunctioning is often caused by poor plug connections. In particular in the automotive industry, where electronics are increasingly being used, the quality of plug contacts plays a pivotal role - and this where materials science can come in. Special microscale and nanoscale structures, which can be rapidly and cost-effectively produced using new laser technologies, are now set to ensure increased fail safety. Bumpy surfaces destroy the plug contact - For many years, the number of sensors and processors installed in cars has been growing, and this trend is very likely to continue thanks to the success of the electric car. "When you drive a car over a bumpy, uneven surface, making the whole vehicle vibrate, it's really the worst thing for the plug contacts", Prof. Carsten Gachot from the Institute for Engineering Design and Logistics Engineering at TU Wien explains.
