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.
