Abstract
Electro-adhesion grippers for holding workpieces, are disclosed as including a first electrode and a second electrode that mutually engage, in a plan view of the electrodes, wherein, at least in a sub-region, the first electrode and the second electrode correspond to the border lines of a two-dimensional fractal space-filling curve of a second or higher order, and wherein the border lines result from enclosing a shape of the space-filling curve on both sides on an auxiliary grid that is offset with respect to a grid of the space-filling curve by half a grid spacing in each grid direction.
