Abstract
Halitosis or oral malodour originates with the anaerobic bacterial degradation of sulphur containing amino acids within the oral cavity resulting in the emission of hydrogen sulphide (H2S), methyl mercaptan (CH3SH) and dimethyl sulphide (CH3SCH3), collectively known as volatile sulphur compounds (VSCs). The sensing of VSCs is needed for dentistry as well as for auto-ventilation applications. This paper discusses the design and development of the portable and low cost metal oxide based gas sensor for the foul odour applications. The substrate design, the sensor parameters and the proposed in-house works are described.
