New Architecture of Fiber-Shaped Organic Electronic Devices for Advanced Flexible and Wearable Applications

With the increasing interest in electronic textiles as an ideal platform for next-generation wearable electronics, fiber-shaped electronic devices that can be embedded directly into textiles are of particular interest. One-dimensional architectures with three-dimensional surfaces of fibrous electronic devices and their reconfigurable integration into network structures are attracting a lot of attention in a new field of technology called “Fibertronics”. This presentation describes recent progresses in fiber-shaped electronic devices based on organic semiconductor engineering. New device architectures consisting of (i) double-stranded microfiber assembly, or (ii) spirally wrapped microelectrodes, and device manufacturing processes will be provided to overcome the inherent limitations of microfiber form factors. We will discuss the electrical performances of demonstrated fibrous devices, including organic transistors, artificial neuromorphic transistors, and photodiodes, and their potential applications for human signal monitoring or neuromorphic machine learning.
