Fabrication of capacitors using the radial dynamic magnetic field assembly. a Fabrication routine for the radial magnetic field assembling approach. b Planar polymeric and capacitor stack. c Magnetic rotor self-assembly during which the sacrificial layer dissolves and the hydrogel layer swells. d Assembly of capacitors in an external rotating magnetic field by winding the unstrained capacitor nanomembrane stack onto the magnetic rotor. (Inset) Assembled capacitors after fabrication. e Time sequence of winding process. Bottom image shows assembled array of capacitors. Scale bar is 1 mm. f Electric performance of planar and assembled capacitors 5 and 10 mm in length measured in H2SO4 electrolyte
