歪誘起液相分子吸着脱離特性の制御技術の確立とマルチ分子検出センサの開発

在过去的一年。为了验证应变对石墨烯基气体传感器气敏性能的影响，我们成功地开发了样品。该传感器采用化学气相沉积（CVD）技术在铜基板上制造，并转移到柔性基板上进行可控弯曲。通过测量石墨烯薄膜在不同气体浓度下的电阻来表征样品的气敏性能。结果表明，该传感器对NO2和NH3具有良好的灵敏度。此外，在压缩应变下，石墨烯气体传感器对1 ppm NO2和10 ppm NH3的响应增加，表明应变的影响可以提高石墨烯传感器的气敏性能。

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.
