In the past year. Samples have been successfully developed to verify the effect of strain on the gas sensing performance of graphene-based gas sensors. The sensors were fabricated using chemical vapor deposition (CVD) on copper substrates and transferred onto a flexible substrate for controlled bending. The gas sensing performance of the samples was characterized by measuring the electrical resistance of the graphene film under different gas concentrations. The results showed that the sensors had good sensitivity to NO2 and NH3. Furthermore, the response of the graphene gas sensors to 1 ppm of NO2 and 10 ppm of NH3 was found to increase under compressive strain, indicating that the effect of strain can enhance the gas sensing performance of graphene sensors.
