    Self-Powered Piezoelectric Nano-Polymer Networks with Embedded Wireless Nodes for Distributed IoT Sensor Platforms

    By R.Nathiya, Deobarat Kumar Chandan, S. Duraisivam, K.Kannan, J. B Veeramalini, B. Parvathi Sangeetha, Ashok Kumar Chaudhary, Jayarama Pradeep, Rajendiran M

    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 …

    Bio-Derived TPS–Lignin Hybrid Composites Reinforced with Modified Coir and Plantain Fibers for Eco-Efficient Structural Applications

    By Nantha Kumar P, Nagasrisaihari Sunkara, Sachin S. Harak, A. Vijayalakshmi, DVSSSV Prasad, Karanam Suresh Babu, Kirubakaran D, S.Dhivya, Rajendiran M

    Abstract: This study develops bio-derived polymer composites using a thermoplastic starch–lignin (TPS–lignin) matrix reinforced with alkali-treated coir and plantain fibers for sustainable load-bearing applications. The TPS–lignin matrix was formulated using cassava starch, glycerol, and 10 wt% lignin, while coir and plantain fibers were surface-modified using 5 wt% NaOH to enhance interfacial compatibility. Composite laminates were fabricated with varying fiber loadings (10–40 wt%) through melt-mixing and hot-press compression. Tensile, thermal, morphological, and …

    Nano-Silica Reinforced Crosslinked Biopolymer–PCM Composites for Improved Thermal Cycling Durability

    By Narendra Pothula, R. Sundar, S. Shalini, Karanam Suresh Babu, K. Hema Latha, A. Parvathi Priya, Kurmana Premakumar, S. Savitha, Rajendiran M

    Abstract: Crosslinked biopolymer–PCM composites reinforced with nano-silica were developed to enhance thermal cycling durability, leakage resistance, and structural stability for advanced thermal energy storage applications. A starch-based biopolymer was chemically crosslinked using citric acid to create a stable polymer network, while paraffin was employed as the phase-change medium and nano-silica (1–4 wt%) served as a multifunctional inorganic reinforcement. FTIR analysis confirmed successful esterification between citric acid and the polymer backbone, indicated …
