High-resolution printing of conformal circuits on curved surfaces is critical to achieving structure-function integration in electromechanically coupled components like antennas. However, existing printing techniques such as inkjet or extrusion-based printing fail to conformally deposit microscale conductive circuits on freeform curved surfaces with curvature variations. Herein, we propose an innovative electrohydrodynamic (EHD) printing strategy that can adaptively adjust the nozzle-to-substrate distance and printing velocity according to surface curvature, enabling the direct printing of conductive circuits on diverse curved surfaces with microscale resolution and high uniformity. A path-planning algorithm is developed based on the target surface morphology captured from the scanned 3D point cloud data. The printing velocity at each point along the printing trajectory can be adaptively calculated according to the Gaussian curvature and mapping angle. This strategy makes the deposition rate well match the stage's moving speed, facilitating the uniform EHD printing of conductive patterns with a line width of 39.31 ± 4.06 μm on different surfaces with curvatures ranging from 10 to 2000 m
