Fiber-based wearable electronics has gathered great interests as a ideal platforms with conformable wearing sensation. Ultimately, to realize weaving-based e-textile system development of the functional fibers integrated with electronic component has been required. To date, organic field-effect transistors (OFETs) based on wire or fiber-shaped substrate have been demonstrated, however the devices were formed at one side of the fiber due to limited coating technology of functional materials. In this work, we have demonstrated the polymer dielectric/organic semiconductor core-shell fibers by die-coating of polymer/semiconductor blend solution. Vertical phase-separation of the blend solution realized polymer dielectric (inside) /semiconductor (outside) bilyers wrapped fibers in a one-step coating process. The resulting OFET devices exhibited the charge-mobility comparable to that of the device based on a flat substate. |
