Role within the Collaborative Research Centre
This project will collaborate closely on the sensor design with the technology groups in research area A as well as with the modeling activities in research area B.
A1: Magnetostrictive material parameters and domain properties are obtained from
A1 and calculations of stress distributions in magnetostrictive layers are compared to the experimental results in A1.
A2: Finite element method calculations of mechanical deformations provided to
A3: Close collaboration concerning the design of resonant ME sensors. Material parameters and fabrication restrictions are obtained from
A3. Sensor layouts are provided to A3. Experimental and theoretical results are compared to interpret and improve the sensor behavior. Tuning of the sensor frequency and quality factor are investigated jointly.
A4: Close collaboration concerning the design of ΔE-effect ME sensors. Material parameters and fabrication restrictions are obtained from
A4. Sensor layouts are provided to A4. Experimental and theoretical results are compared to interpret and improve the sensor behavior.
A5, A6: Finite element method calculations of mechanical deformations provided to
A5 and A6.
A7: Sensor designs for electric modulation are provided to
A7. A comparison of experimental and theoretical results is employed to enhance the simulations method and provide better predictions.
B1: Noise models developed in
B1 will be integrated into the simulation software and SNR values for complex sensor geometries will be provided to B1.
B3: Jointly the effect of non-ideal, i.e., extended sensors with fabrication variations, on the solution of the inverse problem will be investigated.
B7: Together with
B7 also effects regarding caused by the sensor geometry will be investigated.
Exchange on modeling topics with other projects will take place in the focus group F1 “Modeling”. The project will also be active in the focus group F2 “Sensor Concepts” to discuss fabrication possibilities and provide sensor layout suggestions. This project will support the dissemination activities in project SOP and the doctoral researchers will be active in the IRTG.
