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 ...

Current Trends in Fluid Viscous Dampers with Semi-Active and Adaptive Behavior

Applied Sciences, 2023
Fluid viscous dampers (FVDs) have shown their efficiency as energy-dissipating systems, reducing the effects induced on structures by dynamic loading conditions like earthquakes and winds. In this paper, the evolution of this technology is reviewed, with

Computer simulations of electrorheological fluids in the dipole-induced dipole model

, 2001
We have employed the multiple image method to compute the interparticle force for a polydisperse electrorheological (ER) fluid in which the suspended particles can have various sizes and different permittivites.

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

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 ...

Electric alignment of plate shaped clay aggregates in oils

Frontiers in Physics, 2016
We experimentally investigate the rotation of plate shaped aggregates of clay mineral particles immersed in silicone oil. The rotation is induced by an external electric field.

Electrical controlled rheology of a suspension of weakly conducting particles in dielectric liquid [PDF]

, 2006
The properties of suspensions of fine particles in dielectric liquid (electrorheological fluids) subjected to an electric field lead to a drastic change of the apparent viscosity of the fluid. For high applied fields (~ 3-5 kV/mm) the suspension congeals

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

The Electric Field Responses of Inorganic Ionogels and Poly(ionic liquid)s

Molecules, 2020
Ionic liquids (ILs) are a class of pure ions with melting points lower than 100 °C. They are getting more and more attention because of their high thermal stability, high ionic conductivity and dielectric properties.
