Abstract
A self-cleaning humidity sensor based on Mg2+/Na+-doped TiO2 nanofiber mats is provided. Examples show the response and recovery characteristic curves for ten circles with the RH changing from 11% to 95%. The nanofibers are manufactured by mixing together a metal salt comprising titanium, a magnesium compound, a sodium compound, and a high molecular weight material to form a mixture, electrospinning the mixture to form composite nanofibers, and calcining the composite nanofibers to yield a TiO2 nanofiber material doped with magnesium and sodium.
