a, Optical image of twelve 100-pixel BOC chips. b, Average resistance of sensors. The sample size used to derive statistics is 12. The error bars indicate the standard deviation (SD). Data are presented as mean values +/- SD. c, Standard deviation of resistances. d, Coefficient of variation of resistances. e, Average gas response of sensors. The sample size used to derive statistics is 12. The error bars indicate the standard deviation (SD). Data are presented as mean values +/− SD. f, Standard deviation of gas responses. g, Coefficient of variation of gas responses.
