Biomimetic Gradient Porous Core–Shell Fibers with Enhanced Gas Sensing for CO‑Temperature Dual‑Mode Early Fire Warning

Caption

  • A biomimetic gradient porous core–shell fiber with enhanced gas-sensing capabilities for CO-temperature early fire warning is fabricated via a coaxial wet-spinning technology.
  • The gradient porous sheath with SnO2/In2O3 heterojunction endows enhanced CO gas-sensing performance with high sensitivity, low detection limit and improves the CO respond of by 15%.
  • The CO-temperature dual-mode sensing fiber integrated with a wireless early fire-warning system achieves a rapid respond to fire in ~3 s and detects 10 ppm CO gas within 19 s.
