Structure of the CRC 1261 The work within the CRC is organized into two project areas and comprises 14 research projects in total. Project area A, ”Sensor Technology”, covers the range from materials research on novel magnetoelectric composites and their constituents (projects A1 and A2) to the research on new sensor concepts (projects A3, A4, A5, A7) including their in-situ structural characterization (project A6) and materials and sensor modeling (project A8). Project area B, “Magnetoelectric Sensor Systems for Medical Applications”, uses sensor concepts of project area A and deals with analog and digital signal processing (projects B1 and B2), the solution of the inverse problem (project B3) and four different life science applications (projects B5, B6, and B7) that are considered to be in the range of the sensors’ performance within the first funding period. The integration of medical projects at an early stage is a specific characteristic of the CRC 1261. It will ensure the provision of specific sensor targets and specifications for medical applications as well as the evaluation of the sensors’ performance using realistic and medically relevant problems. Both are considered to be key factors in the success of the overall aims of the CRC. As a consequence, this approach requires a continuous, dedicated, interdisciplinary orientation of the CRC with the participation of internationally well-recognized groups from materials science, electrical engineering and medicine of the University of Kiel (CAU) in collaboration with the Fraunhofer Institute of Silicon Technology (ISIT) and the Leibniz-Institute for Science and Mathematics Education (IPN) throughout all three funding periods. The two research areas will be complemented by two service projects (projects Z1, Z2), the Integrated Research Training Group (project IRTG), the public relations project (project SOP) and the administrative project. The structure and the main collaborations of the CRC 1261 are shown in the figure above. Further collaborations of the two research areas A and B and the two service projects are fostered by three focus groups, which are dedicated to organizing the work on the overarching topics “Modeling” (Focus Group F1), “Sensor Concepts” (Focus Group F2), and “Biomagnetic Signal Analysis” (Focus Group F3).
