Magnetically Actuated Liquid Crystals
Nano Letters, 2014 Ferrimagnetic inorganic nanorods have been used as building blocks to construct liquid crystals with optical properties that can be instantly and reversibly controlled by manipulating the nanorod orientation using considerably weak external magnetic fields (1 mT).

Ironless magnetically levitated planar actuator [PDF]
Journal of Applied Physics, 2008 This paper describes a magnetically levitated planar actuator with moving magnets. This ironless actuator has a stationary coil array above which a translator with a permanent-magnet array is levitated and propelled in the xy plane. During the movements in the xy plane, the set of active coils is switched, as a result of which the stroke in the xy ...

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.

Light- and magnetically actuated FePt microswimmers [PDF]
The European Physical Journal E, 2021 AbstractExternally controlled microswimmers offer prospects for transport in biological research and medical applications. This requires biocompatibility of the swimmers and the possibility to tailor their propulsion mechanisms to the respective low Reynolds number environment.

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2010 Clearance change between a magnetic head with a thermal flying-height control (TFC) function and a magnetic disk at high altitude was investigated. To clarify the change of head-disk clearance in the case of TFC actuation at high altitude, head-disk ...

Surface micromachined magnetic actuators [PDF]
Proceedings IEEE Micro Electro Mechanical Systems An Investigation of Micro Structures, Sensors, Actuators, Machines and Robotic Systems, 2002 A surface micromachined micromagnetic actuator (also called a magnetic flap) as an integrated part of an active micro electromechanical fluid control system is described. The flaps are fabricated by surface micromachining technology and are capable of achieving large deflections (above 100 /spl mu/m) with magnetic forces in stationary air.
