(Color online) Schematic steps of the micropipette based suspended polymer fiber drawing method for a single fiber case: Step A: Raise the substrate until it comes into contact with the polymer droplet. Step B: Move the micropipette vertically with a constant speed and stop at a constant height. Step C: Move the stage along a predetermined trajectory with a constant speed while forming the solid polymer fiber by the evaporation of the solvent. Step D: Contact the substrate with the pipette to suspend the fiber. Step E: Break the fiber or continue to draw subsequent ones.
