Stretchable electronic devices are considered as main components for wearable electronics. Semiconducting nanofibers (NFs) have been regarded as promising candidates as active layers for stretchable electronics. Generally, electrospinning is considered a powerful method for fabrication of 1-D nanomaterials with various compositions. Herein, we report NF-based transistors with high stretchability and transparency based on core-shell NFs. Because of the composition of the electrospun core-shell NFs as stretchable and semiconducting part, fabricated coresshell NFs showed high stretchability compared with semiconducting single NFs. For the fabrication of stretchable transistors, elastomeric polymers were utilized for substrate and dielectric layers. As a result, the stretchable NF-based transistors showed stable device operations with various strains. Our results demonstrate the high potential of coreshell NFs for use as stretchable active layers in wearable electronics.
