Flexible electronic devices are considered key components of wearable smart electronics. Sensors based on organic field-effect transistor (OFET) platforms have recently attracted great interest due to their flexibility, easy amplification of the detected signals. 1-D nanostructured conducting fibers have been considered particularly strong candidates as novel active layer for chemical sensor with high flexibility and volume to surface ratio. However, nanofiber is hard to be utilized as the active layer of the OFET devices because of its surface roughness. Herein, we report highly flexible OFET-based on a 1-D electrospun polymer semiconducting nanofibers. The chemical sensor with 1-D electrospun fibers showed highly stable device performance under low voltage and in ambient condition. Furthermore, we designed a novel sensing system for the detection of various organic gases. The results clearly showed possibility of application for our devices toward the wearable chemical sensors. |
