Abstract Although the adoption of self‐powered energy harvesting technologies is rapidly increasing, fabrication flexible, easy‐to‐assemble, highly sensitive, and energy‐efficient devices continues to pose a significant challenge. Electrospun nanofibrous film‐based triboelectric nanogenerators (TENGs) show great promise for mechanical sensor applications due their flexibility, wearability, lightweight, high electrical output. Herein, polydopamine (PDA)‐treated silver (Ag) nanoparticles (NPs)‐decorated titanium dioxide (PDA‐Ag/TiO 2 NPs) innovatively incorporated into an electrospun Nylon 66 polymer construct PDA‐Ag/TiO nylon composite film (NCNF)‐based TENGs (PAT@NCNF TENGs). The prepared films display dielectric conductive properties, improving output performance TENG. PAT@NCNF TENG systematically studied by varying filler material embedded in polymer. assembled exhibits ≈370 V, ≈15 µA, ≈5.4 W m −2 with excellent pressure sensitivity ≈7.88 V kPa −1 . proposed used harvest various forms biomechanical power electronic gadgets. Finally, effectively employed multifunctional sensing systems monitor actions, detect impact objects, facilitate Morse code transmission human gait monitoring applications.
