US Patent 10910960 Energy harvesting system based on reverse electro wetting on dielectric

An energy harvesting system based on reverse electro wetting on a dielectric includes: a dielectric material layer molded with a dielectric material in a panel shape and including an upper end and a lower end; and an electrode layer including a plurality of electrodes coupled to a lower surface of the dielectric material layer. In particular, the upper end of the dielectric material layer is located higher than the lower end and allows a liquid drop to flow from the upper end to the lower end, and the dielectric material layer generates dielectric polarization in the dielectric material layer and continuously varies a flow rate of the liquid drop between the upper end and the lower end of the dielectric material layer. The plurality of electrodes are disposed to be spaced apart from one another in a direction from the upper end to the lower end.
