Magnetic Microspheres for MPI and magnetic actuation [PDF]
, 2022 Magnetic particle imaging (MPI) systems do not only allow for the visualization of the distribution of magnetic nanoparticles, but the magnetic fields of an MPI scanner can be also used to apply a magnetic force or a torque. This enables the actuation of

Magnetic actuation of hair cells [PDF]
Applied Physics Letters, 2011 The bullfrog sacculus contains mechanically sensitive hair cells whose stereociliary bundles oscillate spontaneously when decoupled from the overlying membrane. Steady-state offsets on the resting position of a hair bundle can suppress or modulate this native motility.

Magnetically Actuated Colloidal Microswimmers
The Journal of Physical Chemistry B, 2008 To achieve permanent propulsion of micro-objects in confined fluids is an elusive but challenging goal that will foster future development of microfluidics and biotechnology. Recent attempts based on a wide variety of strategies are still far from being able to design simple, versatile, and fully controllable swimming engines on the microscale. Here we

Computation of magnetic field in an actuator [PDF]
Simulation Modelling Practice and Theory, 2008 Abstract Design and optimization of an actuators based on magnetostrictive technology requires computation of the magnetic field. The “MS”-technology offers an attractive controllability with high power density. The magnetostriction is a reversible feature which can be used in various actuator layouts.
