Investigation of graphene composite based gas sensor for E-nose application

Serious studies have been made on how to improve the performance of enose system. This is typically based on the chemo resistive sensor which mainly depends on the sensing material. These factor leads to the era of searching new sensing material which can give contribution to e-nose system. The prev...
