Detection of Pressure or Flow Rate Variations in MR Valves through Magnetic Flux Analysis

Yves Perriard, Yoan René Cyrille Civet, Daniel Grivon

Magneto-Rheological (MR) fluids consist in a suspension of ferromagnetic particles dispersed in a fluid carrier. If excited by a magnetic source, the nearby magnetic field induces the particles magnetization with the formation of chainlike structures align ...

Experimental Investigation of the Dynamic Performances of a Miniature Soft Magneto-Rheological Shock Absorber

Yves Perriard, Yoan René Cyrille Civet, Daniel Grivon

In the proposed work, the dynamic performances of a miniature soft Magneto-Rheological (MR) shock absorber are analyzed. The final application for which the damper has been designed and in which it will be embedded is a variable stiffness insole for patien ...

Diabète. Chaussures intelligentes pour patients diabétiques

Yves Perriard, Yoan René Cyrille Civet, Daniel Grivon

Les taux d’ulcération et d’amputation des membres inférieurs chez des patients diabétiques demeurent très élevés et sont donc inacceptables. Les récidives d’ulcères plantaires qui augmentent le risque d’amputation sont fortement liées à la difficulté d’obt ...

Bingham-Papanastasiou and Approximate Parallel Models Comparison for the Design of Magneto-Rheological Valves

Yves Perriard, Yoan René Cyrille Civet, Daniel Grivon

Magneto-Rheological Fluids (MRFs) are smart materials whose physical properties can be controlled by an exciting magnetic field. MRFs are described as Bingham plastics with variable magnetic field dependent yield stress. Thanks to their particular features ...
