Graphene-based sensors
Webgraphene-based chemiresistive gas sensor. The graphene sits atop a substrate and is contacted with two planar metal contacts. Gas molecules in the vicinity of graphene can interact with the sensor, which is reflected in a changing electrical resistance between the two contacts with changing gas concentration or type. WebDec 7, 2024 · Graphene-based composites can improve the sensitivity and flexibility of traditional sensors and shorten the reaction time. There is no doubt about the role of graphene in sensors, but how to select appropriate graphene-based materials according to their applications has become a problem [ 2 ].
