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.
