Reverse-electrowetting harvester

Matrix context

D = disequilibrium row · C = coupling family column. A cell reads the state of the atlas for that pair.

   arrays of droplets oscillated against nanometre-thick multilayer dielectric films at tens of hertz; three configurations (28 mm² and 8 mm² liquid–substrate overlap per droplet) gave the same level — the abstract's 'high power densities, up to 10³ W m⁻²' is the authors' stated potential of the method, with no assumptions or denominator in the text read, so it is not recorded; the '≈ 1 mW per droplet-electrode' the atlas carried until pass 37 appears nowhere in the paper

best recorded power density (derived)

≈ 10² W/m² per liquid substrate overlap area — instantaneous electrical power density, device, 2011; instantaneous resistive-load electrical power divided by the instantaneous / maximum liquid–substrate overlap area as the experiment defines it — an active-interface density, not a device-footprint one
