Magnetostrictive bilayers for multi-functional sensor families

Objective

New bilayer (BL) material category as a basic element for multi-functional sensor families with potential to replace many conventional sensor types (e.g. temperature, acceleration) through identical design. BL consisting of a magnetostrictive layer (ML) and a nonmagnetic counter-layer (CL), bending yielding pure compression in the ML as a basis for a sensor signal (sensitivity adjustable by the CL- design). Development of production procedures (sputtering, agglutination, melt spinning) for macro-BL strips (thickness order 100 µm) by P1/HES, micro-BLs (1 µm) by P2 / HES and BL-wires (>1 µm) by P3/REC mainly using amorphous MLs. Material characterization by P4/REC. Signal establishment methods including non-contact detection. Applicability tests for automotive sensors (e.g. vehicle driver condition, torque) by P5/IND and clinical monitoring (skin sensors for cardio-respira- tory functions, catheder sensors for blood velocity, temperature, etc.) by P6/IND.
