Scavenging the ambient energy is possible through various methods. The concept, Triboelectric Nanogenerator (TENG) is an emerging and promising technique. Herein, we propose an innovative application of TENG to enhance the endurance of Multi-Rotor Unmanned Aerial Vehicles (UAV). A novel study on the part of electrostatic induction using COMSOL for the application in the TENG is made and optimised. Post triboelectrification, the triboelectric charges in the polymers induce electrostatic charges on the back electrode. Based on Gauss law of electricity, the contact surfaces of Polymer and its back electrode are modified and simulated. The customization of the surface pattern ensures the angle of the incident electric field to the normal vector of the surface
is in the range of 0o to 30o . This technique enhances the electric flux experienced by the back electrode resulting in increased polarisation.
The metal-polymer composite tends to improve the triboelectric
properties of the polymers. The Composite of PDMS with Ag particles increase the charge density of the PDMS during triboelectrification. A LabVIEW DAQ controlled test rig was built to monitor and store the data, the force readings
from the sensor is utilised to relate work done to the power generated. Using the acquired data, Simulation and analysis, the results showed the output voltage of 10 V with 2 mA⋅m-2 current density for a single 5 cm x 5 cm film. A possible array with a drive mechanism can successfully harness the reaction
force of the thrust produced by the multi-rotor UAV. The Simulation results
indicate the calculated force per film as ~97 N, calculated Voltage as ~112 V
with a current density 6.8 mA⋅m-2. Hopefully; this can be developed for self
powered drones in the future.
