Abstract

We present the development of a stretchable platform-based nitrogen dioxide (NO₂) gas sensor that operates at room temperature (RT). This study investigates the impact of incorporating metal oxide nanoparticles (NPs) into a chemiresistive NO₂ gas sensor, utilizing reduced graphene oxide (rGO) as the primary sensing material. By introducing mesoporous ZnFe₂O₄ (ZFO) NPs at different concentrations into the rGO sensing layer, the performance of the gas sensor is significantly enhanced. The inclusion of ZFO NPs, which possess high-density defect sites, contributes to fast response and recovery times across a wide range of NO₂concentrations (150 to 4000 ppb). Various transient parameters are analyzed to assess the effects of ZFO NPs integration. The rGO-ZFO-based gas sensor exhibits improved sensitivity and reproducibility. Moreover, these sensors, integrated into a stretchable platform and capable of RT operation, open possibilities for the development of advanced wearable NO₂ gas sensors in the future.
