This work reports on a novel magnetorheological polymer gel with carbon nanotubes and carbonyl iron particles mixed into the physical cross-linked matrix. The resulting composites show unusual nonlinear magneto-electro-mechanical responses. Because of low matrix viscosity, effective conductive paths formed by CNTs were mobile high-performance sensing characteristics observed. In particular, due...

Brain-computer interface (BCI) is combination of hardware and software systems that allows the severely or partially disabled persons to communicate with their surroundings. The study of brain activities precisely is an important step in BCI system. Many invasive and non-invasive neuro-imaging techniques are being conducted. In this paper, a comparative analysis of these different approaches ha...

It has been known for over twenty years that the Coulomb solution in Maxwellian electro/magneto-statics for a point charge at the origin in 3-space is unstable when embedded in a non-abelian gauge theory with large coupling constant. A version of this phenomenon was first seen by Mandula [Ma] and other manifestations of it were described in some detail by Sikivie and Weiss [SW1]-[SW3], Jackiw, ...

Iron-filled magnetorheological polymers, when cured in the presence of a magnetic field, result in having a transversely isotropic structure with iron particles forming chains along the direction of applied magnetic induction. In this work, we model the magneto-viscoelastic deformation (and magnetization) process of such polymers. Components of the deformation gradient and the applied magnetic ...

The magnetorheological elastomers (MREs) are novel multifunctional materials which their viscoelastic properties can be varied instantly under an application of applied magnetic field. Due to field-dependent stiffness and damping properties, MREs have been widely used in the development design MRE-based adaptive vibration isolators absorbers also biomedical engineering. Moreover, due inherent m...

Size-dependent vibrational and instability behavior of fluid-conveying magneto-electro-elastic (MEE) tubular nano-beam subjected to magneto-electric potential and thermal field has been analyzed in this study. Considering the fluid-conveying nanotube as an Euler-Bernoulli beam, fluid-structure interaction (FSI) equations are derived by using non-classical constitutive relations for MEE material...
