Electrospinning apparatus and electrospinning method

An electrospinning apparatus, comprising

• a compartment that comprises at least one chamber adapted to contain a substance from which fibers are to be formed, said at least one chamber being electrically charged at a chamber potential;
• and
• a collector adapted to collect said fibers from said at least one chamber, said collector being electrically charged at a ground potential different from said chamber potential, thereby establishing an electric field between said at least one chamber and said collector,
• wherein said at least one chamber comprises a forming layer comprising a plurality of openings through which said substance is extruded into said fibers.

An electrospinning method, comprising:

• supplying a substance from which fibers are to be formed to at least one chamber of a compartment;
• electrically charging said at least one chamber at a chamber potential;
• and
• electrically charging a collector adapted to collect said fibers from said at least one chamber at a ground potential different from said chamber potential, thereby establishing an electric field between said at least one chamber and said collector;
• and
• wherein said substance is extruded into said fibers through a plurality of openings which are present at a forming layer of said at least one chamber.
