Abstract: Flexible electronics have excellent flexibility, enabling seamless integration with clothing, and have great potential in various practical wearable applications. One-dimensional fibrous electronic devices have become a research hotspot in the field of smart wearables due to their excellent flexibility, weavability and comfort. First, the research progress of one-dimensional stretchable electrodes for fiber-like flexible electronic devices is reviewed, and then introduced the high-performance one-dimensional fibrous flexible electronics representative during the preparation of conductive material, manufacturing technology, as well as the further application of the one-dimensional flexible fiber become various main preparation methods for all kinds of electronic devices. Finally, we think critically about the opportunities and challenges of one-dimensional wikis smart wearable electronics.
