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.
