Abstract
Self-powered sensing systems are emerging as a promising solution for next-generation distributed Internet of Things (IoT) platforms, where lightweight, flexible, and low-maintenance devices are required for continuous monitoring. In this work, a self-powered piezoelectric nano-polymer network based on poly-vinylidene fluoride (PVDF) reinforced with BaTiO₃ nanoparticles and multiwalled carbon nanotubes (MWCNTs) was developed for flexible wireless sensing applications. The composite was designed to combine mechanical flexibility, enhanced piezoelectric response, and real-time wireless data transmission within a single material platform. The fabricated nanocomposite film was prepared through solution casting, electrical poling, and electrode integration, followed by coupling with an ESP32 wireless node for IoT-based signal acquisition. Structural and electromechanical evaluation showed that the optimized PVDF/ BaTiO₃ / MWCNT network generated a stable open-circuit voltage of up to 8.9 V under applied mechanical loading and retained nearly 90% of its initial output after 1000 bending cycles, demonstrating good durability and flexibility. The output voltage also increased with actuation frequency, reaching 9.6 V at 5 Hz, confirming reliable dynamic sensing performance. Wireless monitoring experiments further verified that the generated voltage signals could be successfully transmitted in real time to a remote interface. Overall, the developed piezoelectric nano-polymer network provides an effective route toward flexible, self-powered, and wireless IoT sensor platforms for structural, wearable, and environmental monitoring applications.
Keywords: nano-polymer, multiwalled carbon nanotubes, electromechanical evaluation, poly-vinylidene fluoride, piezoelectric response.
