A systematic study of the dynamics of chain formation in electrorheological fluids

AIP Advances, 2021
We report a systematic study of the dynamics of chain formation in electrorheological fluids using Brownian dynamics simulations. The parameters of the system such as applied electric field, polarizability, dipole moment, friction coefficient, and number

Modulating Stiffness and Shape of a Soft, Textile‐Based Structure Through Glass Transition of a Conductive Phase‐Changing Polymer

Advanced Materials Technologies, Volume 10, Issue 11, June 5, 2025.
A variable stiffness structure with shape morphing and shape memory capabilities made from layered textiles and 3D printing material is developed. Direct printing of cPLA on textile electrodes maximizes the electrodes' contact area. This work presents a new method for achieving variable stiffness in small segments of soft, deformable structures, using ...

Towards spatially selective efferent neuromodulation: anatomical and functional organization of cardiac fibres in the porcine cervical vagus nerve

The Journal of Physiology, Volume 603, Issue 7, Page 1983-2004, 31 March 2025.
Abstract figure legend Functional, in vivo imaging was performed in pigs by means of selective vagus nerve stimulation with a multi‐electrode cuff in conjunction with physiological readouts of organ‐specific activity. These data were analysed and correlated to the electrode positions to determine the functional map. Subsequently, the pig was killed and

Characterization and Testing of an Electrorheological Fluid Valve for Control of ERF Actuators

Actuators, 2015
Previous studies of electrorheological fluids (ERFs) were motivated by brake, clutch, damping, haptic and resistive applications, but never motivated towards developing an ERF based-hydraulic rotary actuator. One design to make such an actuator is to use

Statistical-mechanical theory of the overall magnetic properties of mesocrystals

, 2004
The mesocrystal showing both electrorheological and magnetorheological effects is called electro-magnetorheological (EMR) solids. Prediction of the overall magnetic properties of the EMR solids is a challenging task due to the coexistence of the ...

Effect of a Nonlinear Energy Sink on the Nonlinear Panel Flutter Suppression Under Variable Temperature Rise and Airflow Yawed Angle

International Journal of Aerospace Engineering, Volume 2025, Issue 1, 2025.
This study investigates the nonlinear aeroelastic response behaviors and robustness of a square isotropic panel with a nonlinear energy sink (NES) considering temperature rise and airflow yawed angle. Considering uniform temperature rise, the nonlinear aerothermoelastic equations for a three‐dimensional (3D) isotropic panel with an NES were derived ...

An Energy Framework to Control Viscoelastic Semi‐Active Devices in Plan‐Wise One‐Way Asymmetric Systems

Structural Control and Health Monitoring, Volume 2025, Issue 1, 2025.
This study proposes new strategies for the semi‐active control of the dynamic response of a plan‐wise asymmetrical structural system using viscoelastic devices. Different from some literature proposals, these innovative strategies are designed to be immediately interpretable, aiming to optimize the different terms of the energy balance equation through

A magnetorheological fluid damper for robust vibration control of flexible rotor-bearing systems: A comparison between sliding mode and fuzzy approaches [PDF]

Journal of Theoretical and Applied Vibration and Acoustics, 2017
Squeeze Film Dampers (SFD) are commonly used for passive vibration control of rotor-bearing systems. The Magnetorheological (MR) and Electrorheological (ER) fluids in SFDs give a varying damping characteristic to the bearing that can provide active ...
