Focus Groups The structure of the CRC 1261 relies on the two project areas A “Sensor Technology” and B “Magnetoelectric Sensor Systems for Medical Applications” with a total of 14 research projects supported by two service projects, the Integrated Research Training Group and the public relations project. Although the projects follow five different sensor approaches for obtaining sufficient limits of detection at biomagnetic frequencies and four different application areas, there are a number of overarching scientific questions that will be addressed by so-called focus groups. The structure of the focus groups was adapted and refined during the first funding phase. Today, we have six groups named f1 to f6: Focus groups Leader f1 Magnetic Layers Dirk Meyners f2 Modelling Martina Gerken f3 Comparison of Sensor Concepts Michael Höft f4 ME Sensors Jeffrey McCord f5 Concepts based on ΔE-effect Franz Faupel f6 Biomedical Applications Gerhard Schmidt The focus groups are action groups across projects that foster exchange between projects on particular aspects. Each focus group will have regular meetings on a monthly basis for presentations and comparison of achieved results. The participating projects are committed to send at least one representative to the focus group meetings and to address overarching aspects.
