Electronic noses based on polymer‐like carbon nitride (CN x ) are investigated by these authors. The gas‐sensing properties of CN x are examined, focusing on the detection of humidity and ammonia. Two basic types of gas sensor—capacitance and microelectromechanical (see Figure)—are discussed. It is found that the sensors are highly sensitive, stable, and have short response and recovery times.
