Role within the Collaborative Research Centre
Project B7 takes ME sensors towards bioengineering applications. As the project is based on the expertise of a number of other projects (e.g. on sensor design, fabrication, simulation), there are many connections to and interactions with other projects.
A1: The quality of the magnetic films will directly improve MPM, especially FeCo/FeTb thin films will be interesting, because of their reduced permeability, which leads to better spatial resolution.
A2: Aero-polymer networks.
A3: Development of resonant sensors.
A5: Investigation of ΔE-sensor system noise with respect to applied signals and operation of sensor electronics.
B1: The analog sensor front-end will be adapted to the special needs of MPM with project
B2: The real-time system, developed in project
B2, will improve with signal acquisition and post processing.
A8: Transfer of noise models to be integrated into the more general multiscale numerical modeling of ME sensor systems in order to accurately predict the limit of dectection (LOD).
B2: Definition of the optimal interface between analogue and digital processing. Combined analogue and digital signal processing, including iterative improvement of measurement performance through successive application of digitally derived correction signals in the analogue domain.
B3 will combine the forward calculations and measurements of known particle distributions to develop a solution of the inverse problem.
Z1: Small sensors are crucial for high spatial resolution, hence miniaturized MEMS sensors are important.
Z2: Promising sensor candidates will be characterized and preselected in cooperation with
Project B7 will contribute to the focus group F3 “Biomagnetic Signal Analysis”. Project-related Publications
