尽管最近在静电纺丝方面取得了进展，但通过使用静电纺丝纤维来创建高度有序的结构是不可能的。这是由于静电纺丝射流的混沌运动，这意味着纤维的沉积位置覆盖几厘米的半径。因此，电纺纤维的应用局限于不需要精确定位的应用。然而，通过使用钢刀片来控制电场，现在可以创建由高度对齐的纳米纤维制成的纤维束，其中纤维束的端部在静电纺丝期间被固定。由静电纺丝纤维束制成的高度有序结构的创建现在是可能的，因为纤维束足够坚固以被处理，并且还容易将纤维束转移到基底上。更重要的是，在纤维束的两端已知的情况下，将纤维束自动转移到基底上是可能的。
Despite recent advances in electrospinning, creating highly ordered structure through the use of electrospun fibres is not possible. This is due to the chaotic motion of the electrospinning jet which means that the deposition location of the fibres covers a few centimetres radius. As a result, applications for electrospun fibres are restricted to applications where precise positioning is not required. However, through the use of steel blades to control the electric field, it is now possible to create a fibre bundle made of highly aligned nanofibres where the ends of the fibre bundle are fixed during electrospinning. The creation of highly ordered structures made of electrospun fibre bundles is now possible since the fibre bundle is robust enough to be handled, and it is also easy to transfer the fibre bundle onto a substrate. More importantly, with the two ends of the fibre bundle known, automating the transfer of the fibre bundle onto a substrate is a possibility.
