A finite element approach for the implementation of magnetostrictive material terfenol-D in automotive CNG fuel injection actuation [PDF]

open access: yes, 2008
Magnetostriction is the deformation that spontaneously occurs in ferromagnetic materials when an external magnetic field is applied. In applications broadly defined for actuation, magnetostrictive material Terfenol-D possesses intrinsic rapid response ...

Methodology for artificial microswimming using magnetic actuation [PDF]

open access: yes, 2011
We propose a methodology for swimming at low-Reynolds-number flows based on ciliary motion of a microswimmer using magnetic actuation of artificial cilia.By solving the coupled magnetic-elastic-hydrodynamic problem, we demonstrate nonreciprocal effective

Targeted mechanical stimulation via magnetic nanoparticles guides in vitro tissue development

open access: yesNature Communications, 2023
Tissues take shape through a series of morphogenetic movements guided by local cell-scale mechanical forces. Current in vitro approaches to recapitulate tissue mechanics rely on uncontrolled self-organization or on the imposition of extrinsic and ...

Molecular Dynamics Studies of Shape Memory Polymers: From Bead–Spring Models to Atomistic Simulations

open access: yesAdvanced Engineering Materials, EarlyView.
Coarse‐grained (left) and atomistic (right) models of the shape memory polymer ESTANE ETE 75DT3 are shown schematically. The two representations bridge molecular detail and mesoscopic description. Both models capture shape memory behavior, linking segmental mobility and conformational relaxation of anisotropic chains to macroscopic recovery, and ...

Fabrication of magnetic shape memory micropillars using femtosecond pulsed laser

open access: yesNext Materials
Magnetic shape memory (MSM) alloys, particularly Ni–Mn–Ga single crystals, exhibit a magnetic field induced strain (MFIS) of up to 6–12% at room temperature, making them promising candidates for high-frequency, contactless actuation in miniaturized ...

Superlubricity and Corrosion Inhibition Properties of Solvate Ionic Liquids in Hybrid Carbon Fiber Reinforced Plastic–Steel Interfaces

open access: yesAdvanced Engineering Materials, EarlyView.
Solvate ionic liquids lubrication reduced the coefficient of friction by ∼60% compared to dry sliding, reaching steady‐state values as low as 0.04–0.05. Corrosion weight‐loss measurements in 1 M HCl further demonstrated significant inhibition behavior, with only 100 ppm of [Li(G3)][TFSI] (∼68.5 μL/L) reducing corrosion‐product weight loss by 63 ...

A Polymeric Bilayer Multi-Legged Soft Millirobot with Dual Actuation and Humidity Sensing

open access: yesSensors, 2021
There are numerous works that report wirelessly controlling the locomotion of soft robots through a single actuation method of light or magnetism. However, coupling multiple driving modes to improve the mobility of robots is still in its infancy.
