The overarching aim of the Collaborative Research Centre (CRC) 1261 is the establishment of a biomagnetic diagnostics system based on magnetoelectric sensors for magnetoencephalography (MEG) and magnetocardiography (MCG), respectively, and to demonstrate its potential on selected medical diagnosis problems. The detection of magnetic field distributions in the region of the head or torso promises powerful diagnosis practices of brain (MEG) or heart (MCG) functions. Systems used as routine diagnostic tools need to be easy-to-handle and cost-effective, thus the operation of uncooled sensors is desirable. Magnetic field sensors based on miniaturized magnetoelectric composites have revealed their potential to detect sub-picotesla fields at room temperature under certain conditions.
Thus, the general objectives of the CRC 1261 are the research and development of different magnetoelectric sensor approaches with a special focus on high sensitivity at biomagnetic frequencies (Project Area A) and their evaluation and utilization in medically relevant questions (Project Area B). The research program to pursue these goals requires intensive interdisciplinary collaboration between materials scientists, electrical engineers and physicians (neurology and cardiology). It will be supported by two service projects on microsystem sensor fabrication and on magnetoelectric sensor characterization. An Integrated Research Training Group will be established with the intent of fostering interdisciplinary collaboration within the CRC 1261 and providing the best possible research experience and training to our doctoral researchers. Furthermore, a Scientific Outreach Project will be responsible not only for outreach to the public, school students and teachers, but also for strengthening the interdisciplinary scientific communication within the CRC with a special focus on doctoral researchers.
