First magnetic materials with sensitivity for the physical quantity “curvature”

Contactless flow detection with magnetostrictive bilayers

“…As a further alternative to our previous work [1], the induction coil was placed directly upon the excitation coil, aiming for a compact designed system. We used a 100 windings excitation coil and a 50 windings induction coil with dimensions as given above.…”

“…The basic performance of the here applied bilayers with respect to magnetic, hysteretic, mechanical and thermal characteristics of ML and CL, respectively, has been described in the above listed papers [1][2][3][4][5], among many others. Thus, the following is restricted to specific aspects of the here applied higher order harmonics signal detection system.…”

“…Magnetostrictive bilayer (BL) materials, sensitive to bending or temperature changes, provide the possibility to detect different measurement quantities such as displacement, curvature [1], temperature, etc. [2][3][4][5][6][7].…”

Influence of phase transformation on interfacial activity and bend sensitivity of rapidly quenched Fe 77.5 Si 7.5 B 15 /Co 72.5 Si 12.5 B 15 bilayered magnetostrictive ribbons

“…These bilayered ribbons are relatively newer class of rapidly quenched materials circumscribing a range of processing challenges, but stemming up with potential sensor applications. These ribbons in view of their functionalized layers, reveal enhanced sensor properties, opening their scope in automotive industries, aviation and bio-medical instrumentation [1][2][3].…”

Magnetostrictive bilayer sensor system for testing of rotating microdevices

“…In this paper the development of such a highly sensitive torque measurement system, using novel, magnetostrictive bilayer force sensors [2,3] will be presented.…”
