Focus Groups

On a daily basis, much of the interaction between projects was driven by the close collaboration of the young researchers. To give the collaboration between the semi-annular retreats a formal framework, we established focus groups. These focus groups are action groups spanning projects and foster exchange between projects on particular aspects. Each focus group has regular meetings for presentations, discussions, and comparisons of achieved results. The participating projects are committed to send at least one representative to the focus group meetings and to address overarching aspects. Joining forces in the focus groups minimizes redundancy among the projects and allows for common research on overlapping topics.

We started with three focus groups dedicated to "Modelling", "Sensor Concepts", and "Biomagnetic Signal Analysis". As the focus group "Sensor Concepts" turned out to be very large (including about 70% of the CRC projects), we restructured the focus groups in 2018 with now six focus groups covering the topics mentioned in the table below.

The dates of the indival focus group meetings can be found here.

Name Description Lead
F1 - Magnetic Layers The performance of magnetic layers is a key cross-project topic. Thus, material-related issues, domain engineering, stress control, and other related topics are discussed in this focus group. Dr. Dirk Meyners
F2 - Modelling The focus group unites all activities on device and system modelling within the CRC. In detail this means material and domain modelling, modelling of non-linear effects, simulation of mechanical and electromagnetic characteristics, simulation of signal strengths and noise contributions, to mention just a few modelling aspects. Prof. Dr. Martina Gerken
F3 - Comparison of Sensor Concepts This focus group is dedicated to establishing common definitions of sensor performance parameters such as sensitivity, frequency behavior, or limit of detection (LOD). Measurement procedures are defined to allow for comparability of performance results. Prof. Dr. Michael Höft
F4 - Magneto­electric Sensors This focus group bundles all activities on ME sensors based on piezoelectric and magnetostrictive composite materials. Prof. Dr. Jeffrey McCord
F5 - Concepts based on Delta-E Effect In this focus group, all concepts based on a change of the elastic modulus by a magnetic field are considered. This includes Delta-E-effect cantilever sensors as well as suface acousitc wave (SAW) sensors. Prof. Dr. Franz Faupel
F6 - Biomedical Applications This group focuses on the use of magnetic field sensors in different applications. Joint topics include the mounting of sensors for measurements and multichannel measurements as well as signal processing and application related aspects. Prof. Dr. Gerhard Schmidt
