Fiber electronics have attained considerable attention since they provide an ideal device platform of flexible, light weight, and comfortable wearing. Despite of many efforts to achieve stretchable fiber electronics, the stiffness of conductive materials severely degrades the electrical performance of these devices above certain strain/stress conditions. Here, we report a novel concept of a fiber-based transistor comprising metal-coated polymer microwire electrodes that can be stretched and released by external stimulation and elasto-capillary motion, respectively. In particular, conductive microwire electrodes can be extremely stretchable (greater than a few hundred %) and self-recoverable by controlling the critical buckling load that remains below the capillary force between the wire and the wetting liquid phase. The fiber transistor contains organic semiconductor/insulator/conductive gate wire and source-drain wires crossed, respectively, as warp and weft. |
