Abstract
Proposed are triboelectric generator using a lubricant-infused surface controlled by a magnetic field and a manufacturing method thereof. The triboelectric generatorincludes a substrate, an electrode unitpositioned on the substrateand including a first electrodeand a second electrode, a stabilization layerpositioned on the substrateand the electrode unitand including a first elastic polymer, and a magneto-controllable unitpositioned on the stabilization layerand including a lubricantand a plurality of protrusion-shaped microcomposites, in which the microcomposite includes a magnetic materialand a second elastic polymer. 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.
