Abstract
This article presents conversion of rotational motion into electrical energy using triboelectricity. For this purpose, aluminium and fluorinated ethylene propylene (FEP) films are selected for generating charges during rotational motion. Energy density and power are computed by optimizing various resistors and capacitors. The maximum energy density is found to be 2560 μJ/cm3 across 33 μF. The maximum power is found to be 6.5 μW across 1 M $\Omega$ resistor after 400 s. With the availability of such commercially available materials, it is possible to generate a lot of energy, which depends on the size of the system and type of materials. Such portable systems can be used for harvesting wind energy for low power electronic devices.
