Transfer of Energy and Momentum Between Magnetoactive Surface Microstructure and a Solid Object

open access: yesAdvanced Engineering Materials, EarlyView.
We demonstrate that magnetoactive multilamellar arrays subjected to a rotating magnetic field can function as platforms for controlled transport of physical objects. Through systematic experimental investigation, we elucidate the underlying physical mechanisms determining the upper limit of the achievable transportation speed in such magnetic “conveyor‐

Recent progress on the magnetorheological plastomers

open access: yesInternational Journal of Smart and Nano Materials, 2015
Different from the traditional magnetorheological (MR) fluids and elastomers, the magnetic particles in the plastic MR materials are not ‘deadly’ trapped in the polymer matrix; thus, the MR plastomers exhibit higher MR effects and lower sedimentation ...

MagPiezo: A Magnetogenetic Platform for Remote Activation of Endogenous Piezo1 Channels in Endothelial Cells

open access: yesAdvanced Functional Materials, EarlyView.
MagPiezo enables wireless activation of endogenous Piezo1 channels without genetic modification using 19 nm magnetic nanoparticles and low‐intensity magnetic fields. It generates torque forces at the piconewton scale to trigger mechanotransduction in endothelial cells, standing as a novel platform to interrogate and manipulate Piezo1 activity in vitro.

Asymmetric Dynamic Model of Temperature-Dependent Magnetorheological Damper and Application for Semi-active System

open access: yesFrontiers in Materials, 2019
As a semi-active hydraulic device, the magnetorheological (MR) damper's damping characteristics will be influenced by temperature. In addition, the MR damper with gas accumulator usually shows asymmetric loop characteristics.

A theoretical analysis of a piezoelectric ultrasound device with an active matching layer [PDF]

open access: yes, 2007
This paper investigates the use of magnetically active materials in the matching layer of a piezoelectric transducer. This then allows the performance of the device to be dynamically altered by applying an external field.

Topology and Material Optimization in Ultra‐Soft Magneto‐Active Structures: Making Advantage of Residual Anisotropies

open access: yesAdvanced Materials, EarlyView.
Residual magnetization induces pronounced mechanical anisotropy in ultra‐soft magnetorheological elastomers, shaping deformation and actuation even without external magnetic fields. This study introduces a computational‐experimental framework integrating magneto‐mechanical coupling into topology optimization for designing soft magnetic actuators with ...

Study on the tribological and rheological properties of magnetorheological fluids based on different base oils

open access: yesMaterials Research Express
Base oil has great influence on the tribological and rheological properties of magnetorheological fluid. In this paper, four types of magnetorheological fluid are prepared respectively by silicone oil, mineral oil, synthetic oil (PAO) and castor oil, and
