  • Publication number: 20210371994
    Abstract: A method for forming an ordered array of one-dimensional iron oxide nanostructures involves forming an electrode on a template and forming a plurality of one-dimensional iron nanostructures in the template. A portion of the template is at least partially removed to expose a portion of each of the plurality of one-dimensional iron nanostructures. The plurality of one-dimensional iron nanostructures are annealed while the portion of each of the plurality of one-dimensional iron nanostructures is exposed to form an ordered array of iron-oxide one-dimensional nanostructures. The at least partial removal of the portion of the template involves complete removal of the template or a partial removal so that top portion of each of the plurality of one-dimensional iron nanostructures is exposed and a bottom portion of each of the plurality of one-dimensional iron nanostructures is within the template during annealing.

  • Patent number: 10768058
    Abstract: A magnetic nanocomposite device is described herein for a wide range of sensing applications. The device utilizes the permanent magnetic behavior of the nanowires to allow operation without the application of an additional magnetic field to magnetize the nanowires, which simplifies miniaturization and integration into microsystems. In addition, the nanocomposite benefits from the high elasticity and easy patterning of the polymer-based material, leading to a corrosion-resistant, flexible material that can be used to realize extreme sensitivity. In combination with magnetic sensor elements patterned underneath the nanocomposite, the nanocomposite device realizes highly sensitive and power efficient flexible artificial cilia sensors for flow measurement or tactile sensing.
