Abstract

A system for manufacturing an electrospun structure (10), is disclosed. The system comprises an electrospinning system (20) having a precipitation electrode (22), and a dispenser (24) being at a first electric potential relative to the precipitation electrode and capable of dispensing a liquefied polymer to produce polymer fibers precipitating on the precipitation electrode, thereby to form the electrospun structure thereupon. The system further comprises a subsidiary electrode system (30), being at a second potential relative to the precipitation electrode and configured to shape an electric field formed between the precipitation electrode and the dispenser. The system also comprises a compartment (12), encapsulating the electrospinning system and the subsidiary electrode system, for keeping a clean environment within the compartment.
