An electrostatic thin-shell structure concept capable of actively controlling the shape of large area systems with minimal mass overhead and complexity is described. The structure comprises an assembly of collapsible thin-shell cells for which the cross-section follows the classical collapsible tubular mast architecture. Two conductive electrodes are added to the top and bottom flanges of the cell. An electrostatic force develops between top and bottom electrodes upon voltage application, which flattens the cross-section and causes the cell to expand longitudinally. When multiple layers of these cells are bonded to each other, the controlled differential expansion of each layer can be harnessed to cause global bending.
