Abstract: A semicontinuous process is used to nanoimprint a nanowire ink and form transparent conductive electrodes. Ultrathin gold nanowires are confined in the features of an elastomeric stamp, where they spontaneously assemble upon drying into hierarchical, percolating superstructures. This templated self‐organization yields grids with defined line widths down to 0.9 µm and high pattern fidelity. Metal grids with square, hexagonal, and linear features are printed over 30 cm2 on different substrates and gently sintered in hydrogen plasma. Meshes on polyethylene terephthalate foil show high optical transmittances (>92%) and low sheet resistances (106–168 Ω sq−1). Their resistance is changed by only 10% after 500 bending cycles at a radius of 5 mm. The printed electrodes are used to build capacitive and resistive touch sensor devices.
