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.

A Vibration Isolator Based on Magneto-Rheological Elastomer
2016The paper presents an investigation about a magneto-rheological elastomeric (MRE) pad to be adopted as seismic semi-active isolator for lightweight structures. MRE pad may change its stiffness if immersed in a magnetic field. This characteristic allows to real time shift the fundamental frequency of the isolated structure. In this way it is possible to
