This paper presents the fabrication and characterization of a flexible gas sensor based on TiO2 nanotubes membrane, onto which array interdigitated gold electrodes in one side and a common heater in the backside were obtained using conventional microfabrication techniques. This was used to detect hydrogen sulphide within a concentration range of 6–38 ppm. The response to low concentrations of H2S at low temperature and good stability make the sensor a promising candidate for practical applications. These results support the proposal that the TiO2 nanotubes membrane flexible sensors are promising in portable on-site detection based on low cost nanomaterials. View Full-Text
