ΔE-effect Sensors (A04)

• Subject Area: Synthesis and Properties of Functional Materials ; Electronic Semiconductors, Components and Circuits, Integrated Systems, Sensor Technology, Theoretical Electrical Engineering
• Term: since 2016
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 286471992

We research integrated delta-E-effect sensors as well as 2D and 3D configurations with low noise, and low LOD. The MEMS devices and CMOS readout electronics are manufactured via Europractice and post-processed at Kiel University. Small sensor size increases the local resolution, and mature fabrication technology ensures very high reproducibility. Central hypotheses are: Antiparallel exchange biased multilayers and thicker magnetic layers will improve the LOD of individual sensor elements; Model guided design will yield performance suitable for biomedical application; We can fabricate flux concentrators/guides and magnetic anisotropy orientations with high reproducibility; Wireless signal read-out becomes feasible by edge pre-processing.
