1. A method for performing alternating current (AC)-electrospinning, the method comprising:
disposing a precursor liquid in a reservoir of an electrode system comprising an electrical charging component electrode and at least one of an AC field attenuating component and a precursor liquid attenuating component; and
delivering an AC signal to the electrical charging component electrode from an AC source that is electrically coupled to the electrical charging component electrode to place a predetermined AC voltage on the electrical charging component electrode.
