The proposed wearable smart wireless (WSW) H2S sensor combines nanofabrication and 3-dimensional printing technology (3DPT) to provide sensitive and easy monitoring of H2S gas. The novel technologies of WSW H2S sensor dramatically reduce the required mass, power and volume of current state-of-the-art conventional systems allowing for flexible implementation of the instrument at high safety, and reliability. Minimal crew time is required with a hand-held configuration, and the crew involvement is eliminated with autonomous continuous analysis enabled by wireless function offered by an integrated WSW H2S sensor array. We are developing hybrid structure of graphene (GP) and tin-oxide (SnO2) porous material based wireless sensor nodes based on 3DPT. 3D printed rubber-like matrix is an ideal substrate for flexible gas-sensors because of its large surface area, flexibility, and facilitated mass transfer of analytes to the reaction sites. We also make the 3D rubber-mesh conductive by plating the surface with copper and deposit nano-porous gas reactive metal film, SnO2, using electrodeposition method. The flexible sensor film will be packaged into an integrated system with power supply and communication modules.
