Reversibly texturing active surfaces with spatial and temporal control
2014
Journal of Intelligent Materials Systems and Structures
Textured surfaces, formed through wrinkling and folding, are observed abundantly in nature. We are especially motivated by the unique capabilities of some species of cuttlefish that camouflage themselves by rapidly switching from smooth to textured skin by expressing protuberances called papillae. Inspired by this, we developed a shape memory alloyelastomer composite as a platform for reversible surface texture. A shape memory alloy wire embedded in an elastomer is forced to shrink due to Ohmic
