Recent advances in electrospun fiber basedelectronics

Electrospun fibers occupy an important position in fiber based electronics for their outstanding advantages, i.e. high length-to-diameter ratio, strong flexibility, high uniformity, controllable morphology, low cost and high efficiency in manufacturing. In this review, the development of electrospinning technique is firstly introduced, including design of multi-nozzle and special nozzle to improve efficiency and achieve special structure, regulation of solution and process parameters to deposit fibers with different morphologies, and development of fiber assembling and orientation to realize controllable direct-writing. Then recent researches on fiber based devices through electrospinning are reviewed, i.e. flexible sensor, super capacitor, lithium ion battery, dye sensitized solar cell, filed effect transistor and organic light emitting diode. Finally, the challenges and future directions of the field are prospected.
