Continuous Preparation of Chitosan-Based Self-Powered Sensing Fibers Recycled from Wasted Materials for Smart Home Applications

Currently, the gradual depletion of fossil resources and the large amount of plastic waste are causing serious harm to the land and marine ecology. The rapid development of wearable smart fibers is accompanied by rapid growth in the material demand for fibers, and the development of green and high-performance biomass-based fibers has become an important research topic to reduce the dependence on synthetic fiber materials and the harm to the environment. Here, chitosan is first prepared from the waste material by chemical methods. Then the chitosan-based self-powered induction fibers are prepared by electrospinning core wire technique. Chitosan-based self-powered sensing fiber is ultra-light and flexible, which can achieve about 2500 collisions without damaging the surface. Chitosan-based self-powered sensing fiber can also be used in smart home sensing applications to control home appliance switches with a light touch, which has a great application prospect in smart home and wearable fields.
