Summary: In this study, a novel approach was proposed to enhance power output of a REWOD energy harvester by significantly increasing the total available surface area using perforated silicon wafer electrodes. The maximum current and voltage densities per unit planar area were measured to be 3.77 mu A/cm(2) and 1.05 V/cm(2) respectively. This approach showed significant improvement in power output compared to prior work on planar electrodes.

Summary: Reverse electrowetting-on-dielectric (REWOD) is a novel energy harvesting technique that uses high capacitance dielectric layers and a new leakage barrier layer to minimize current leakage and maximize power output. The laminated structure with TiO2 and Al2O3 shows reduced current leakage and relatively high capacitance compared to single layer structures, producing enhanced power density at low bias voltage. The energy-harvesting performance displays different behaviors about current generation based on the top surface material in contact with conductive droplets.
