    Abstract: Provided is a method of fabricating a micro/nanowire having a nanometer- to micrometer-sized diameter at predetermined positions on an object. The method comprises: preparing a micro/nanopipette having a tip with an inner diameter (dpt) which is substantially the same as the diameter of the micro/nanowire to be fabricated; filling the micro/nanopipette with a solution containing a micro/nanowire-forming material; bringing the solution into contact with the object through the tip of the micro/nanopipette; and pulling the micro/nanopipette apart from the object at a pulling speed lower than or equal to a predetermined critical pulling speed (vc) to fabricate a micro/nanowire having substantially the same diameter as the inner diameter of the micro/nanopipette tip (dpt). The critical pulling speed (vc) is defined by a maximum limit of the pulling speed at which the micro/nanowire to be fabricated has the same diameter as the inner diameter of the micro/nanopipette tip (dpt).

    Abstract: Proposed are triboelectric generator using a lubricant-infused surface controlled by a magnetic field and a manufacturing method thereof. The triboelectric generator 10 includes a substrate 100, an electrode unit 200 positioned on the substrate 100 and including a first electrode 210 and a second electrode 220, a stabilization layer 300 positioned on the substrate 100 and the electrode unit 200 and including a first elastic polymer 310, and a magneto-controllable unit 400 positioned on the stabilization layer 300 and including a lubricant 420 and a plurality of protrusion-shaped microcomposites 410, in which the microcomposite includes a magnetic material 411 and a second elastic polymer 412. The protrusion-shaped microcomposite is partially immersed in the lubricant, improves power generation efficiency, and can perform reversible switching according to the direction of the magnetic field.
