Sensor Behavior of Magneto-Rheological Elastomers
ASME 2010 Conference on Smart Materials, Adaptive Structures and Intelligent Systems, Volume 2, 2010Magneto-Rheological Elastomers (MREs) are composite materials of an elastomer matrix with a magnetic, micron-sized, powder filler. These materials have gained notoriety because they change stiffness substantially when exposed to a magnetic field giving them the capability of acting as a variable spring for numerous applications.

Analysis of magneto rheological elastomers for energy harvesting systems
International Journal of Applied Electromagnetics and Mechanics, 2020Magneto Rheological Elastomers (MREs) are composite materials based on an elastomer filled by magnetic particles. Anisotropic MRE can be easily manufactured by curing the material under homogeneous magnetic field which creates column of particles. The magnetic and elastic properties are actually coupled making these MREs suitable for energy conversion.

Evaluation of magneto-rheological elastomers for spacecrafts
2011This study focuses on the stiffness controllability of magneto-rheological elastomer (MRE) but also on the damping dependency with the magnetic field. It is well known that elastomer visco-elastic behavior is highlighted by elliptic hysteresis loops. Force-deflection loops of MRE were measured for different amplitudes and frequencies conditions.

Microstructure-based modeling of magneto-rheological elastomers
SPIE Proceedings, 2012Filled with iron particles, polymers can be made responsive to magnetic fields. Specifically, the elastomers that change stiffness in response to a magnetic field are usually called magneto-rheological elastomers (MREs). Anisotropic MREs, in which the particles are aligned during curing and form chain-like structures, exhibit a more significant ...

Modeling of Magneto-Rheological Elastomers for Harmonic Shear Deformation
IEEE Transactions on Magnetics, 2012Magneto-rheological elastomers (MREs) are a class of smart materials which can adjust their modulus or stiffness by an applied magnetic field. Thus, MREs can be used as controllable stiffness elements in various engineering systems. In order to use them for engineering applications, characterizations of MRE behaviors under magnetic fields and ...
