About
Deepalekshmi Ponnamma is a materials scientist and polymer researcher whose work sits at the intersection of smart materials, nanotechnology, and energy harvesting. Her research focuses primarily on piezoelectric nanocomposites, flexible electronics, and advanced functional materials, with particular emphasis on engineering next-generation self-powering and sensing devices. Ponnamma's most influential contribution examines the dielectric and piezoelectric behavior of PVDF/Fe–ZnO nanocomposites under γ-irradiation, demonstrating how strategic nanofiller incorporation and radiation treatment enhance β-phase crystallinity—a discovery critical to developing stretchable self-powered devices, earning the work 95 citations. Her comprehensive review of graphene-based smart sensors, actuators, and soft robotics (65 citations) has become a key reference for researchers navigating the rapidly evolving landscape of intelligent systems. More recently, her work on cerium oxide–decorated graphene incorporated into electrospun PVDF-HFP nanofibers pushes the frontier of optical piezoelectric sensing. Beyond energy harvesting, Ponnamma has contributed meaningfully to discussions on polydimethylsiloxane composites, 4D printing, and fiber technologies aligned with Society 5.0 frameworks. Her body of work reflects a sustained commitment to translating advanced nanomaterial science into practical, society-relevant technologies, making her a valuable voice in the global smart materials research community.
