Abstract: Electronic skin (e-skin)- elastic, flexible materials that replicate the sensory capabilities of human skin- has emerged as a transformative field of research. This review paper critically examines the role of Polyvinylidene fluoride (PVDF) and its composites in enabling next-generation e-skin sensors. Unlike prior surveys, this review (i)complies a unified fabrication checklist for PVDF/MoS2 / BaTiO3 – based devices, (ii)presents a normalized benchmark table for recent PVDF and PVDF-composite e-skins, and (iii)introduces a standardize nomenclature of device parameters. We analyze how advanced fillers (e.g., MoS2, BaTiO3) and fabrication protocols improve piezoelectric, piezoresistive, and durability metrics, while also mapping PVDF-based e-skins to Internet of Things (IOT) applications. Key challenges- such a large-scale fabrication, long-term stability, and signal processing- are critically discussed, and future directions including AI-driven adaptive sensing, self-healing materials, and biocompatible integration are highlighted. The study positions PVDF nanocomposites as a central pillar in the advancement of robust, self-powered, and IoT-ready e-skin systems.
