摘要：
The former ovuliferous scales of bio-templated 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.
