| Abstract Scope |
One of the main challenges in the development of microelectronic systems used in technologies such as Internet of Things and 5G is providing them with a reliable and sustainable power source. Traditional batteries are heavy and require frequent charging, which limits their use in small and portable devices. Piezoelectric nanogenerators (PENGs), which can convert body movements into electricity, offer a promising alternative for powering these systems. In this study, lead-free BaTiO₃ nanowires with high piezoelectric properties were vertically grown on flexible and conductive titanium foil using hydrothermal synthesis method. Each step of the process was optimized, and a uniform layer of nanowires with high aspect ratio over 100 was obtained. Atomic Force Microscopy showed that a single nanowire could produce about 0.50 mV of voltage. The 1×1 cm² BaTiO₃-based PENGs generated up to 7.4 V open-circuit voltage and 9.2 μA short-circuit current, demonstrating their potential for powering small electronic devices. |
