Feasibility study of using piezoelectric nanogenerators to power UAVs using vibrations

The use of renewable energy is very important in meeting current and future needs. Vibrations are a good source of energy, especially through piezoelectric nanogenerators. Light, soft and flexible piezoelectric materials such as PVDF can be used to supply part of the electrical energy required by drones. This study was conducted to investigate the possibility of using PVDF / Zno-RGO piezoelectric polymer polymer nanofibers in supplying the required energy of different UAV components. In this study, first, polymer nanofibers were constructed through electrospinning process and then piezoelectric nanogenerator was constructed. Finally, the amount of electrical energy produced and its usability in multi-axis drones were evaluated. A plan was proposed to install a piezoelectric nanogenerator on the arm of a multi-axis drone. The highest output voltage in one of the samples of nanogenerators was 560 mV and in the larger sample was 1870 mV in laboratory conditions and at a frequency of 23 Hz for 5 minutes. The results of this study showed that by using piezoelectric nanogenerators, it is possible to supply part of the electrical energy used by drones and it can be upgraded.
