Triboelectric Nanogenerator-Based Vibration Energy Harvester Using Bio-Inspired Microparticles and Mechanical Motion Amplification

In this work, the novel design of a sliding mode TriboElectric Nano Generator (TENG)—which can utilize vibration amplitude few hundred microns to generate useful electric power—is proposed for first time. Innovative features include motion modification amplify relative displacement TENG electrodes and use biological material-based micron-sized powder at one increase power output. The is designed fabricated with polyurethane foam charged material micropowder PolyTetraFluoroEthylene (PTFE) strips as electrodes. Experimentations on prototype within frequency range 0.5–6 Hz ensured peak density 0.262 mW/m2, corresponding electrode size. Further numerical simulation performed theoretical model investigate influence various parameters generated by TENG. Lastly, application demonstrated in wearable device an in-shoe sensor. Conceptual arrangement sensor presented, simulations are demonstrate that real size deliver 0.747 mW/m2 TENG; voltage will accurately represent foot vertical force patterns.
