Fig. 3: Sensing performance under variable environmental conditions and scenarios.
a Dynamic response of the Zn/Ag/DNO sensor to H2S gas with reduced concentration from 4 to 0.8 ppm under different RH. b Response versus concentration curves of the Zn/Ag/DNO sensor at different RH. n = 3 for each group. The error bars denote standard deviations of the mean. c Dynamic responses of the Zn/Ag/DNO sensor to H2S gas with reduced concentration from 4 to 0.8 ppm under different temperatures. d Response versus concentration curves of the Zn/Ag/DNO sensor under different temperatures. n = 3 for each group. The error bars denote standard deviations of the mean. e Dynamic responses of the Zn/Ag/DNO sensor to H2S gas with reduced concentration from 4 to 0.8 ppm under different external strains. f Response versus concentration curves of the Zn/Ag/DNO sensor under different external strains. n = 3 for each group. The error bars denote standard deviations of the mean. g Sensitivities of the Zn/Ag/DNO sensor versus external strains. Inset is the photograph of the sensor being stretched to 100% strain. The scale bar is 8 mm. n = 3 for each group. The error bars denote standard deviations of the mean. h Dynamic responses of Zn/Ag/DNO sensor to H2S gas in air or N2 background with reduced concentration from 4 to 0.8 ppm. i Sensitivities and theoretical LOD of Zn/Ag/DNO sensor to H2S in air or N2 background.
