Claim 11:
12. An electrospinning apparatus comprising:
a spinning material supply unit;
a nozzle unit in communication with the spinning material supply unit having a nozzle outlet;
a collector unit for collecting a fibre formed during operation of the electrospinning apparatus;
a voltage supply unit for applying a voltage difference between the nozzle unit and collector unit;
an imaging device for capturing an image of a conus of fluid spinning material and the fibre being formed during operation; and
a processing unit connected to the imaging device, spinning material supply unit and voltage supply unit, wherein the processing unit is arranged to determine a shape of the conus by a calibration of the captured image using predetermined dimensions of a reference part of the electrospinning apparatus and edge detection in the captured image, determine from the shape of the conus a spin wire diameter determination area in the captured image, an actual spin wire diameter at the spin wire diameter determination area, and control operating parameters of the electrospinning apparatus based on a difference between the actual spin wire diameter and a desired spin wire diameter.
