The method provides a bladder having an inner surface and an outer surface, the inner surface forming an interior area, the bladder configured to expand or retract so as to change an area of the interior area, (ii) a plurality of magnetic particles suspended in a fluid medium and disposed within the interior area, and (iii) a sleeve disposed on the outer surface of the bladder. The method excites the plurality of magnetic particles by application of an alternating magnetic field to which the particles reaction. The method causes, by the excited magnetic particles, a phase transition to the fluid medium within the interior area which causes the bladder to expand, such that the sleeve confining the bladder generates actuation from the expansion or retraction of the bladder.

An approach to printing a nickel precursor ink on a wide range of substrates for electronics and magnetic applications is disclosed. The nickel ink reduces to elemental nickel following heating. The ink was printed using an ultrasonic aerosol printing technique. By sintering the nickel precursor ink in the presence of a homogeneous magnetic field, the reduced nickel complex formed continuously aligned nickel nanofibers axially aligned with the direction of the magnetic field. The fabrication of aligned interlayered nanofiber films provides opportunities to produce structures with enhanced isotropic electrical and magnetic properties. The resistivity of the film was found to be as low as 0.56 m.Math.cm, and the saturation magnetization was measured to be 30 emu/g, which is comparable to bulk Ni. Magnetic anisotropy was induced with an easy axis along the direction of the applied magnetic field with soft magnetic properties.
