ABSTRACT Ammonia (NH3) detection at room temperature has attracted considerable attention because of the increasing demand for health monitoring, personal safety protection, and industrial manufacturing. Herein, we report the synthesis of polycrystalline SrGe4O9 nanotubes (NTs) via an electrospinning process. These NTs are a new sensing material for the detection of ammonia at room temperature. The SrGe4O9 NTs exhibited a maximum sensing response of 2.49 for 100 ppm NH3, which was increased to 7.08 by decorating the NTs with Pt nanoparticles. Flexible gas sensors were fabricated, which exhibited comparable performance to the rigid device. Additionally, the flexible devices showed excellent flexibility, mechanical stability, and sensing stability under different bending states, manifesting their potential applications in flexible and wearable electronics.
