Fabrication method of functional micro/nano structures over large-area, flexible and high curvature surfaces, by drawing a fiber from a preform

The method for drawing a fiber with a textured surface comprises the following steps: - forming of a preform from which the fiber is to be drawn with a textured surface; - addition of an outer layer to the textured preform to preserve the shape of the texture of the preform surface during the drawing operation; - drawing of a fiber from the preform, whereby the fiber keeps the formed texture of the preform surface and - removing the additional outer layer to leave the original surface textured fiber exposed. The obtained fiber can be used as a mold to form a textured hollow channel in another material, as a surface coating and as a pressure detector.
