  • SELF-CHARGING DROPLET CAPACITOR FOR HARVESTING LOW-LEVEL AMBIENT ENERGY
    Publication number: 20230188056
    Abstract: A self-charging droplet capacitor for harvesting low-level ambient energy is provided. The capacitor includes a conductive liquid droplet, which is placed on a heterogeneous and hydrophobic surface of dielectric materials coated onto a conductive substrate. The substrate and the droplet, along with the dielectric materials in between, form a parallel-plate type capacitor. The droplet is free to move on the surface, and thus, provides a position-dependent variation of capacitance. The surface consists of two regions, each with a different material and thickness. The different strengths of solid-water contact electrification of the two materials give rise to a self-charging mechanism. The variation in thickness allows for the capacitance change required for energy harvesting.
