Electrospun nanofiber-based soft electronics

Electrospun nanofibers have received considerable attention in the field of soft electronics owing to their promising advantages and superior properties in flexibility and/or stretchability, conductivity, and transparency; furthermore, their one-dimensional nanostructure, high surface area, and diverse fibrous morphologies are also desirable. Herein, we provide an overview of electrospun nanofiber-based soft electronics. A brief introduction of the unique structure and properties of electrospun nanofiber materials is provided, and assembly strategies for flexible/stretchable electronics are highlighted. We then summarize the latest progress in the design and fabrication of representative flexible/stretchable electronic devices utilizing electrospun nanofibers, such as flexible/stretchable conductors, sensors, energy harvesting and storage devices, and transistors. Finally, a conclusion and several future research directions for electrospun nanofiber-based soft electronics are proposed.
