5. Main metal oxide sensors and their applications
To date, most of the semiconductor sensors marketed and used industrially are based on tin oxide (SnO 2 ). These are highly sensitive to combustible gases (methane, propane, CO, etc.), but, equally, to many other gases such as ammonia, nitrogen oxides as well as volatile organic compounds (VOCs) and consequently have been widely exploited despite their lack of selectivity. Over the last twenty years or so, other materials have also been used.
5.1 Existing technologies on the market
Among commercialized sensors, other metal oxides have also been used. In addition to the use of tin oxide
