Hierarchically structured polymer fibers encompassing 1-D, 2-D, and 3-D structures with at least onedimension nano- to micro-meters in size have recently received an increasing amount of attention dueto their vast potential in such applications as sensing, medicine, energy storage. This review summarizesadvancements in the last ten years in the design and fabrication of hierarchically structured polymer fibersvia electrospinning technologies, including a diversity of electrospinning devices and electrospinningparameters using various polymers. These well-defined, multilevel structures enable the fibers to beused more effectively in applications in the biomedical field, such as drug delivery, tissue engineering, anddiagnostics. This review can provide a better understanding of the relationships between the structureand functionality of polymer fibers for further biomedical applications.
