This paper presents a conceptual design and theoretical performance analysis of a sustainable footstep energy harvester using Polyvinylidene Fluoride/Barium Titanate (PVDF/BaTiO3) nanocomposite transducers.A compliant bridge-type mechanism is proposed to amplify footstep forces (assuming a 15x amplification factor) and maximize strain in the transducers, while ultra-low cold-start Power Management Integrated Circuits (PMICs) and supercapacitor storage are integrated for efficient energy capture.Theoretical voltage and energy per step are estimated using material properties from literature and plausible assumptions for transducer area, thickness, and force amplification.The study also outlines a conceptual IoT-enabled architecture for autonomous data collection and gait analysis using ultra-low-power microcontrollers.While no experimental validation has been performed, this framework provides a feasible blueprint for energy-autonomous smart flooring applications.
