Wearable electronics have attracted attention as an emerging technology to realize practical e-textile and smart garments. The future of wearable devices is expected to include a wearable automatic system that perceives the requisite information from human skin, clothing, the environment, and some objects. Among various technical approaches, fiber-shaped devices, as representative candidates, have been developed to enable network formation in textiles for practical wearable applications. In this work, we demonstrated fiber-based organic transistor memories by using a simple solution process that can be applied to a variety of fibers for wearable e-textiles. The capillary tube-assisted coating system allowed the formation of smooth and compact nanogranular P(VDF-TrFE) films on flexible and thin metal wires. As a result, the ferroelectric properties of the fiber-shaped polymer film were enhanced, allowing the memory device to operate at low voltages below 5 V. |
