1. A fog-based self-powered system for collecting atmospheric water and generating electricity, comprising:
a mesh-based fog harvester for accumulating water droplets from atmospheric moisture; a droplet distributor configured to receive accumulated water droplets from the mesh-based fog harvester;
a droplet-based electrical generator for harvesting energy from the water droplets accumulated in the droplet distributor;
the droplet-based electrical generator including an electret surface for receiving the water droplets from the droplet distributor and at least two electrodes;
a water reservoir for receiving water droplets from the droplet-based electrical generator.
