The Structural and Mechanical Basis for Passive‐Hydraulic Pine Cone Actuation

Abstract The opening and closing of pine cones is based on the hygroscopic behavior of the individual seed scales around the cone axis, which bend passively in response to changes in environmental humidity. Although prior studies suggest a bilayer architecture consisting of lower actuating (swellabl...
