▎ 摘　　要

NOVELTY - The platform (20) has a chemoresistive gas sensor includes a sensing region with two interconnect regions each extending continuously from the sensing region, the sensing region comprised of porous graphene and a gas-sensitive nanomaterial dispersed in the sensing region operable to deconvolute the gas component from a gas mixture and a substrate supporting the sensor. The chemoresistive gas sensor has a response to the gas component by changing a sensing resistance A of the gas sensing region as the gas-sensitive nanomaterial binds with the gas component such that the gas component can be detected. The interconnect regions are comprised of porous graphene. The gas-sensitive nanomaterial is graphite oxide (rGO), molybdenum disulfide (MoS2), rGO/MoS2, or zinc oxide/ copper oxide (ZnO/CuO) core/shell nanomaterials selected for binding to different gas components respectively. USE - Gas sensing platform for sensing gas component with concentration. ADVANTAGE - The sensing region and the interconnect region as an integral piece provides a mechanically and electrically robust gas sensor. The moderate heating in gas sensing material is still favorable to enable fast response/recovery and enhanced reversibility though room temperature gas sensors eliminated the adverse thermal effect. The accumulation of holes increases the major carrier concentration of the gas sensor, thus decreases the overall resistance. The strain in the LIG sensor is significantly reduced when compared to the applied strain because of the enhanced stiffness in the device region and the placement of the LIG sensor away from the strain concentration edge. The stretchable strategies e.g. pre-strain, self-similar interconnect patterns and kirigami patterning of the substrate is applied that minimizes the strain and reduce the resistance change in the LIG sensing region other than the demonstrated strain isolation strategy. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for making a gas sensing platform for sensing a gas component with a concentration. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a fabrication process of preparing a stretchable laser-induced graphene (LIG) gas sensing platform.
