The former ovuliferous scales of biotemplated cones of Pinus nigra show moisture‐driven actuation similar to their biological templates, demonstrating a facile route to obtain ceramic moisture‐sensitive bilayer actuators. Based on comparative analysis of their hierarchical nanometer‐precision replica structures, using, e.g., spatially resolved small‐angle X‐ray scattering, the origin of the actuation is explained.
