Abstract
Stretchable electronics have garnered significant attention due to their broad applications. However, seeking a trade-off between mechanics and electricity by loading less active material while maintaining multifunctionality and structural stability remains a formidable challenge. Herein, we report a biocompatible, ultrastretchable (3000%), and superconductive (128,975 S/m) composite nanofibrous helix with a periodic alternating structure, fabricated via electrospinning and gradual biscroll winding technology unlike before. The synergistic effect of elastic PU and spring-like structure endows the composite nanofibrous helix with high stretchability. Meanwhile, the liquid metal is stably coiled and locked in the nanofibrous helix, ensuring a continuous conductive pathway. By optimizing the construction pattern and composition content, we engineered light monitoring electronics with a wide working range using the as-prepared nanofibrous helix as a highly stretchable and stable conductor. This versatile and low-cost strategy advances the development of and provides new ideas for structure-function integrated electronics.
