TY - JOUR TI - Detection of cigarette smoke using a fiber membrane filmed with carbon nanoparticles and a fractal current law AU - Xu Ling-Yi AU - Li Ya AU - Li Xiao-Xia AU - He Ji-Huan JN - Thermal Science PY - 2020 VL - 24 IS - 4 SP - 2469 EP - 2474 PT - Article AB - Cigarette smoke will cause irreversible damage to human health and living environment. It is especially important to accurately detect and effectively prevent cigarette smoke. This paper fabricates a fiber membrane filmed with carbon nanopowders as a smoke sensor. The experiment reveals that the fabricated membrane is sensitive to the smoke, two laws are proposed to model the current change of the sensor. Fractal calculus is used to exactly predict the current property at the initial stage, and a fractal modification of the current law is proposed. The present technology provides an economic way to mass-production of smoke sensors.
