Abstract

This study investigates the impact of nanowire and nanosheet dimensions on the performance of BaTiO₃-based nanogenerator systems under low and high-frequency conditions. To achieve this, the effect of compressive loading on individual nanowires and nanosheets is analyzed. Nanowire dimensions range from 20 nm to 500 nm in edge length and 1 µm to 5 µm in height, while nanosheets vary from 100 nm to 500 nm in edge length and share the same height range. For nanowires, increasing height reduces the resonance frequency from 5.87 10 5Hz to 82773 Hz, whereas increasing edge length significantly raises the frequency from 5.87105 Hz to 1.1010 8 Hz. In contrast, for nanosheets, the resonance frequency decreases from 8.92106Hz to8.59106 Hz with increasing height and increases from 0.89107 Hz to 2.07 107 Hz with a larger edge length. These results highlight the size-dependent behavior of piezoelectric nanostructures and provide insight for optimizing energy harvesting in smart home applications.
