Abstract:
Flexible and wearable technologies in environmental monitoring, healthcare, and industrial safety have been made possible by the advancement of chemiresistive sensors. Ammonia is an important sign of food going bad and kidney problems, so we need detection systems that are sensitive, stable, and can work at room temperature, which many traditional metal oxide sensors can't provide. In this study, we present a flexible ammonia sensor based on a Ti-doped ZnO/polymer composite, fabricated via a cost-effective electrospinning method. This approach enabled uniform integration of Ti-doped ZnO nanoparticles into polymeric fibers, improving electron transport and enhancing sensing performance under mechanical deformation. Obtained material also showed good flexible properties. The sensor exhibited strong mechanical stability and maintained high sensitivity across various bending conditions, showing the same response at both 0° and 90° angles. The synergistic effects between the doped metal oxide and the flexible substrate offer a reliable, non-invasive platform for real-time ammonia monitoring in wearable applications.
