Focus Group Details

This focus group encompasses all projects of project area A (A1, A2, A3, A4, A5, A6, A7, A8) and projects B1, B2, Z1 and Z2. It is mainly concerned with aspects of ME sensors that are of general interest for the different sensor concepts and is coordinated by Eckhard Quandt. One important subject is material-related issues such as deposition conditions and post deposition treatment, domain engineering for reduction of magnetic losses, stress control, alternative magnetostrictive and piezoelectric materials as well as exchange coupling for self-biased magnetostrictive materials. Resonator geometries, improvements of electromechanical coupling, and an increase in the quality factor of the resonators are other points, which are highly relevant for all sensor concepts. Since the sensors should in the end be incorporated into sensor arrays, integration into MEMS devices is of particular interest. Here, substantial synergy effects are expected with respect to process development via participation of the central project Z1 in the focus group. The investigation of all sensor concepts also requires extensive characterization in terms of micro and nanostructure, magnetic and piezoelectric properties as well as of the resulting magnetoelectric properties and in particular the limit of detection. Therefore central project Z2 is also an integral part of the focus group. This also holds for projects B1 and B2, which cover all aspects related to operation as well as readout of the sensors and also deal with noise reduction, which is crucial for further improvement of the signal to noise ratio and requires joint efforts from analog and digital signal processing.
