Live safely even in old age – within your own four walls

Joseph von Fraunhofer Prize 2017 – Human-Centered Technology

What to do if you fall in your home? Many elderly people ask themselves these and similar questions; they want security without having to give up their own four walls. A new technology concept, developed by the Fraunhofer Institute for Experimental Software Engineering IESE in Kaiserslautern, Germany, now makes this possible – while also ensuring privacy. A communication tool integrates nursing care consultation and ensures social integration.

Telephone calls clear as a bell

Joseph von Fraunhofer Prize 2017

Smartphones can do almost everything you want, but their poor voice quality is still a vexing issue. Fraunhofer researchers have helped develop a new codec to banish this problem. Their solution raises voice quality to an unprecedented level – making it sound as natural as if the person you’re calling is standing right next to you. That’s because, for the first time, the entire audible frequency spectrum is transmitted.

Cleaning waste water effectively

Joseph von Fraunhofer Prize 2017

Water is vital – therefore, waste water has to be cleaned as efficiently as possible. Ceramic membranes make this possible. Researchers from the Fraunhofer Institute for Ceramic Technologies and Systems IKTS in Hermsdorf, Germany were able to significantly reduce the separation limits of these membranes and to reliably filter off dissolved organic molecules with a molar mass of only 200 Dalton. Even industrial sewage water can thus be cleaned efficiently.

A way out of the chromium ban

Economical alternative to chromium(VI)

Joseph von Fraunhofer Prize 2017

To prevent components from becoming corroded or worn, they are often coated using hexavalent chromium. Starting in September of 2017, though, this will only be permitted with exceptions. The extreme high-speed Laser Material Deposition (EHLA) developed by Fraunhofer and RWTH researchers offers an economic alternative for the first time ever.

Holographic measurement technology at production speed

Joseph von Fraunhofer Prize 2017

Fault tolerance in automobile production is increasingly diminishing. Until recently, this presented suppliers with a problem: There were no sufficient methods for detecting micro defects during production. Visual inspection was the solution of choice, but this is not suitable for in-line measurements in the production process. By developing digital holography to become suitable for production, researchers at the Fraunhofer Institute for Physical Measurement Techniques IPM in Freiburg, Germany have resolved this dilemma. Digital holography makes it possible to fully inspect all parts – in a matter of seconds.
