Quantity and Quality: Novel Sensor Module Ensures Efficient Production

12.03.2013
Flexibility, individuality and efficiency are some of the most powerful driving forces in industrial production.

Defects, especially fractures and wrinkles, slow down production processes and increase the reject rate when forming mass products, e. g. during deep-drawing of automotive parts or the manufacture of prototypes.

Fraunhofer researchers have developed a multifunctional thin film system which is located directly in the main load zones and allows for a sensitive and highly dynamic monitoring of the process. A variety of sensor modules will be presented from April 8 – 12, 2013 at Hannover Messe (hall 3, booth D25 and hall 2, booth D18).

There is almost no room for extras where stress in forming processes is at its highest level. Here, precision is the keyword. Therefore sensor systems that monitor the process are often located far from the critical range of forming tools. Researchers of the Fraunhofer Institute for Surface Engineering and Thin Films develop multifunctional sensor modules that are customized for the respective system and incorporated in the main load zones free of play, thus making a long-term stable acquisition of relevant process parameters possible.

The main part of the thin film sensor system is the DiaForce® layer – an amorphous hydrocarbon coating developed at Fraunhofer IST. The layer combines tribological stability with piezoresistive properties so that the sensor can measure forces directly in the main load zones without suffering from wear. Online monitoring, for example of the draw-in movement of sheet metal during deep-drawing processes, and accurate information acquisition from direct contact with the sheet become possible with the DiaForce® layer.
The sensor module can be applied in a variety of fields: Not only deep-drawing systems but also die-cutting systems are important application areas. Here, the module measures the cutting forces in direct contact with the punch. The thin film sensor system offers maximum flexibility when it is incorporated in washers and, in this form, can be built into virtually any system geometry without much effort, ensuring long-term stable data acquisition and monitoring of the production process.

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

Im Focus: Using graphene to create quantum bits

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.

In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...
