  • EARTO Award for Microsystem of the Fraunhofer IWS Dresden / 2018

    Less animal experiments on the horizon: Multi-organ chip awarded

    Press release (Nr. 13) - Fraunhofer IWS Dresden / October 17, 2018

    On the multi-organ chip, several technical components simulate the interaction of blood circulation and organs in the human body. These include a pump (1), a storage chamber for blood and substances (2), chambers for organs and tissues (3) and valves, which simulate the varying blood flow to different organs.

    Dresden Fraunhofer engineers have developed a so-called "multi-organ chip". This microsystem from the Fraunhofer Institute for Material and Beam Technology IWS Dresden, which has now received an "EARTO Innovation Award" in Brussels, simulates the blood circulation and the organs of animals or humans.

    Micro energy harvesters for the Internet of Things

    Press release (No. 12) - Fraunhofer IWS Dresden / October 10, 2018

    Dr. Roman Tkachov examines a film printed with two different conductive polymers at a dispensing printer in the Fraunhofer IWS Dresden. "PEDOT:PSS" is a polymer with positive charge carriers (“p-conductive”), while “Poly(Kx[Ni-itto])” transports negative charge carriers (“n-conductive”). This also shows that IWS polymers can be processed using standard techniques such as printers or rotary coating.

    Thin organic layers provide machines and equipment with new functions. They enable, for example, tiny energy recuperators. In future, these will be installed on pipes or other surfaces in order to convert waste heat into electricity. The experts at the Fraunhofer Institute for Material and Beam Technology IWS Dresden use ink based on conductive polymers for this purpose.

    Micro fishbones to stop car fuel thirst

    Press release (No. 9) - Fraunhofer IWS Dresden / September 12, 2018

    Ultra-short laser pulses generate micro-patterns in engine parts such as piston rings and thus reduce friction (r.). The Fraunhofer IWS technology is designed to reduce wear and friction and save fuel.

    Dresden Fraunhofer engineers are working on reducing the fuel consumption of cars by more than a tenth. They use ultra-short laser pulses to generate very fine and friction-reducing fishbone patterns in engines.

    (Dresden, August 8, 2018) Filigree engravings on external surfaces of aircraft are intended to ensure that airflow remains smooth and drag on the aircraft low. For this, engineers at the Fraunhofer Institute for Material and Beam Technology IWS, the Technische Universität Dresden and Airbus have developed a laser process that produces textured surfaces at high throughput making surface contamination more difficult.

    The Fraunhofer Institute for Material and Beam Technology IWS has succeeded in increasing the stability of those aircraft engine parts which are subject to stress due to temperature. The IWS process helps to reduce kerosene consumption as well as CO2 emissions. In combination with further measures, significant cost savings result during flight operations. The research project was developed in close cooperation with the engine specialist Rolls-Royce. The first engines with the new technology are already in use.

    The next generation‘s laser wire processing optics "COAXwire" is in the starting blocks. At the Hannover Messe and the ILA Berlin, the Fraunhofer-Institut für Werkstoff- und Strahltechnik IWS Dresden presents two versions of its coaxial wire optics. A completely newly developed miniaturized version enables high-precision processing of complex components with fine wire. In a macro version, the head can be equipped with a hot-wire module.

  • Fast direct joining of metal and thermoplastic materials / 2018

    Bonding without adhesive

    Press release (No. 3) - Fraunhofer IWS / February 20, 2018

    In order to adapt the HCPI process for industrial applications, IWS scientists developed a modularly designed joining gun that can be mounted on a robot arm instead of a spot welding gun.
    © Fraunhofer IWS Dresden

    The Fraunhofer-Institut für Werkstoff- und Strahltechnik IWS Dresden has developed a new process for joining materials with different properties. Thermal direct joining presses laser-structured metal with thermoplastic components and heats them locally. This causes the thermoplastic to melt, to penetrate into the structures and to adhere to the surface. A specially developed joining gun generates robust connections within seconds. The "HeatPressCool-Integrative" (HPCI) process is highly suitable for replacing complex adhesive processes.
