Flexible textile sensors are increasingly used in wearable electronics, structural monitoring, and biomedical applications due to their adaptability and responsiveness to external stimuli. These sensors rely on conductive materials embedded in polymeric matrices to achieve electrical functionality while maintaining flexibility. However, optimizing their electrical conductivity without compromising mechanical properties remains a key challenge. This study focuses on fabricating electrospun thermoplastic polyurethane (TPU) nanofibers enhanced with carbon-based conductive fillers to detect air filter clogging. Different concentrations of conductive particles were incorporated into the polymer solution, and the resulting nanofibrous membranes were evaluated for structural, mechanical, and electrical properties. The impact of filler dispersion and percolation on conductivity was analyzed, highlighting the trade- offs between increased electrical performance and potential material aggregation. Alternative methods, such as surface modifications, were explored to improve charge transport pathways. In addition to applications in smart textiles and biomedical sensing, these conductive membranes show promise for real-time clogging detection in air filtration systems. By monitoring changes in electrical resistance, they can provide early warnings of filter clogging, optimize maintenance schedules, and improve efficiency. The findings offer valuable insights into tailoring electrospun conductive nanofibers for both wearable technology and industrial sensing applications.
