Abstract
An apparatus for producing a fibrous material. The apparatus uses a first material source within which is disposed a first material and a second material source enclosing a second material. The first and second materials to be electrospun. A first and second tip attached to an end of the first and second material sources, with a collector spaced apart from the first and second material sources. A first and second electric field generator each produces a first and second signal each in the form of a sine wave and having a first and second frequency. The fibers are formed from the first and second materials as extracted from the respective first and second tips responsive to a first and second electric field generated between the respective first and second tips and the collector.
