dc.description.abstract This thesis presents the analysis and modelling of electrostatic energy harvesters based on renewable green materials. Conventional and new regenerative electrostatic energy harvesters are designed to power small portable devices. A method of preparing and fabricating the different layers of the mechanically variable capacitors for the energy harvester is developed. The physical and chemical properties of the different layer materials are evaluated by measuring the film thickness, observing the carbon coating conditions, assessing stress and strain, performing thermal analysis, and measuring the conductivity. Several electrostatic energy harvester structures are analyzed and their performance compared. New regenerative electrostatic energy harvesters are designed to achieve a wider output power range and good conversion efficiency. The proposed regenerative electrostatic energy harvesters do not need a startup battery and have only one energy harvesting element. The improved output power range demonstrated in the simulation and measurement results and the simplicity of implementation makes the proposed regenerative electrostatic harvester a suitable solution for integration and for small autonomous systems. en_US
