Magnetic Fluid-Driven Vine Robots for Minimally Invasive Tissue Biopsy Sampling. [PDF]

Adv Intell Syst
This study introduces a magnetic fluid‐powered vine robot for minimally invasive biopsies. The robot uses fluid pressurization for locomotion and external magnetic fields for precise steering. Its soft structure and high magnetic volume ensure controlled movements and stabilization, enabling effective tissue penetration.

Microstructure and magnetorheology of graphite-based MR elastomers

Rheologica Acta, 2011
This study focuses on the magnetorheology of graphite-based magnetorheological elastomers (Gr MREs). By introducing graphite to conventional MREs, the Gr MREs with various graphite weight fractions are fabricated. Both steady-state and dynamic tests were

The Modeling of Magnetorheological Elastomers: A State‐of‐the‐Art Review

Advanced Engineering Materials, Volume 25, Issue 16, August 2023., 2023
This review paper aims to comprehensively discuss the various methods used to model magnetorheological elastomers (MREs), including continuum‐based, microstructure‐based, and data‐driven phenomenological methods. One novel aspect of this review is its inclusion of the effects of temperature on the static and time‐dependent viscoelastic behavior of MREs.
