Abstract: A fog-based self-powered system for collecting atmospheric water and generating electricity is presented. The system includes a mesh-based fog harvester for accumulating water droplets from atmospheric moisture. A droplet distributor receives accumulated water droplets from the mesh-based fog harvester. A droplet electrical generator harvests energy from the water droplets accumulated in the droplet distributor. The droplet electrical generator includes an electret surface for receiving the water droplets from the droplet distributor and at least two electrodes. A water reservoir receives water droplets from the droplet electrical generator.
