Materials and Transducers Toward Selective Wireless Gas Sensing

Innovative approaches of materials and transducers based on selective wireless gas sensing are being developed to solve the problems of sensor selectivity in realistic conditions. The development of sensing materials based on new materials design concepts and new materials fabrication principles will produce a large impact for new sensor system. Significant work conducted on carbon nanotubes and graphene is aimed to meet the challenge of finding a functionalization approach that will suppress humidity effects. Assembly of porphyrins and related molecules into polymers and nanostructures could bring new sensing capabilities due to the possible surpamolecular nature of these assemblies and charge distribution between individual molecules. The importance of studies on improvements of stability of sensing materials will increase because of the need for wireless sensing.
