Doubling the Magnetorheological Effect of Magnetic Elastomers

ACS Polymers Au
One of the most important properties of soft functionalized magnetic composite materials in view of their technological potential is given by the magnetorheological effect. It describes the change in rheological properties such as the shear modulus by application of external magnetic fields.

A nonlinear fractional-order model of soft magnetorheological elastomers for applications in vibration isolation

Journal of Low Frequency Noise, Vibration and Active Control
The magnetically tunable modulus of soft magnetorheological elastomer offers broad applications in vibration control. This material exhibits an obvious Payne effect that the dynamic modulus decreases as the strain amplitude increases.

A Self‐Healing Permanent Magnet Putty for Soft Robot Skins With Force Sensing and Functional Recovery

Advanced Robotics Research, EarlyView.
Permanent magnet putty (PMP) integrates high‐coercivity NdFeB particles with a dynamic polyborosiloxane–Ecoflex matrix, achieving rapid self‐healing (90% mechanical recovery in 10 s) and magnetic recovery within 20 min. With twice the sensitivity of commercial putties, PMP enables precise 5–30 N force detection and discrimination between pressing and ...
