Semiconducting nanowires (NWs) hold great potential for high-performance flexible electronics. This work demonstrates a lithography-free approach for flexible electronics, synthesizing ZnO nanowire arrays directly at pre-defined locations, followed by seamless dry contact printing onto rigid and flexible substrates. The ZnO NWs based printed nanoscale electronic layers exhibit excellent spatial uniformity (NW length, 18-26 µm) and alignment (88-96°). The patterned electronic layers were further processed (e.g. printed conductive tracks) at room temperature to develop proof of concept UV photodetectors. This “design to fab” approach simplifies fabrication, eliminating lithography and enabling resource-efficient, large-area flexible electronics.
