Battery-operated resistive sensor based on electrochemically exfoliated pencil graphite core for room temperature detection of LPG

The present paper illustrates a description on material synthesis, sensor fabrication and electronic prototyping of a cost effective, reusable, stable and highly sensitive and selective device for the sensing and quantification of trace concentrations of liquefied petroleum gas (LPG) in ambient conditions. Conductive colloidal solution of graphene synthesized via electrochemical exfoliation of 9B pencil graphite core was used for sensing LPG at...
