Role within the Collaborative Research Centre
Because mechanical resonances in ME sensors are an important approach for increasing the sensor performance, the concepts of project A3 are essential for most work within the CRC1261, especially with regard to the B projects. The collaborations in detail are:
A1: Characterization of and reconcilement with regard to magnetostrictive phases.
A2: Collaboration concerning MEMS compatibility and fabrication.
A4: Fabrication of different resonant ME sensors for the use as ΔE-effect sensors, collaboration in the characterization of the sensor’s properties.
A5: ME sensors for piezotronic measurements.
A6: TEM characterization of shape memory alloys for ME sensors.
A7: Collaboration on high Q sensors for electric field modulated sensors.
A8: Modeling of resonant sensors.
B1: Design of analogous signal processing for different resonant ME sensors, noise density characterization.
B2: Fabrication of narrow-band ME sensors.
B5: Resonant, narrow band ME sensors for deep brain stimulation.
B7: Fabrication of narrow-band resonant sensors for 3D-Imaging of magnetically labeled cells.
Z1: Use of partially processed wafers based on the technology platform, collaboration in the fabrication of newly developed resonant sensors.
Z2: Collaboration in the limit of detection (LOD) characterization.
Project A3 will contribute to the focus group F1 “Modeling” and F2 “Sensor Concepts” on issues of sensor technology and concepts. Project-related Publications
