Modeling and Motion Control of a Magnetically Navigated Microrobotic System
This paper presents a technology for remotely navigating a magnetized microrobot in three-degree-of-freedom (3-DOF) using magnetic energy. The magnetic energy source is a magnetic drive unit that consists of six iron-core electromagnets, a soft-iron yoke, and a soft-iron pole-piece. The dynamic models of the magnetically navigated microrobot were derived from the magnetic field model in the wor...
متن کاملMagnetically driven colloidal microstirrer.
Paramagnetic colloidal particles dispersed in water and deposited above magnetic bubble domains of a uniaxial ferrimagnetic garnet film are used as microscopic stirrer when subjected to external rotating magnetic fields. The hydrodynamic flow field above the stirrer is detected by tracking of nonmagnetic microspheres. The vorticity of the flow falls off inversely proportionally to the distance ...
متن کاملFormation of Magnetically Supported Disks During Hard-to-Soft Transition in Black Hole Accretion Flows
We carried out three-dimensional global resistive magnetohydrodynamic (MHD) simulations of the cooling instability in optically thin hot black hole accretion flows by assuming bremsstrahlung cooling. General relativistic effects are simulated by using the pseudo-Newtonian potential. Cooling instability grows when the density of the accretion disk becomes sufficiently large. We found that as the...
متن کاملMagnetically driven single DNA nanomotor.
In biological systems, nanoscale molecular motors can generate forces from spontaneous reactions of energy-rich molecules, mostly adenosine triphosphate (ATP), to convert chemical energy into mechanical movement. These motors are roughly 10 nm in size, take steps of a few nanometers, and can exert forces in the piconewton range. [ 1 , 2 ] However, to effi ciently design and construct nanoscale ...
متن کاملSelf-Folding Thermo-Magnetically Responsive Soft Microgrippers
Hydrogels such as poly(N-isopropylacrylamide-co-acrylic acid) (pNIPAM-AAc) can be photopatterned to create a wide range of actuatable and self-folding microstructures. Mechanical motion is derived from the large and reversible swelling response of this cross-linked hydrogel in varying thermal or pH environments. This action is facilitated by their network structure and capacity for large strain...
