Abstract
Apparatus and method for electrospinning fibers in which the apparatus includes a spray head having a longitudinal axis and including at least one electrospinning element disposed in a peripheral wall of the spray head surrounding the longitudinal axis. The electrospinning element includes a passage by which a substance from which the fibers are to be electrospun is provided to a tip of the extrusion electrospinning element. The electrospinning element extends from the peripheral wall in a direction from the longitudinal axis and is configured to electrospin the fibers by electric field extraction of the substance from the tip of the extrusion electrospinning element. Accordingly, the method includes providing a substance from which the fibers are to be composed to a tip of an electrospinning element in a peripheral wall of a spray head having a longitudinal axis, rotating the spray head or a collector configured to receive the fibers around the longitudinal axis, applying in a direction from the longitudinal axis of the spray head an electric field to the tip of the electrospinning element to electrospin by electric field extraction the substance from the tip of the electrospinning element to form the fibers, and collecting the fibers on the collector.
