Mechanical Self-Assembly of a Strain-Engineered Flexible Layer: Wrinkling, Rolling, and Twisting

Self-shaping of curved structures, especially those involving flexible thin layers, is attracting increasing attention because of their broad potential applications in, e.g., nanoelectromechanical andmicroelectromechanical systems, sensors, artificial skins, stretchable electronics, robotics, and drug delivery.

Gravity induced crease-to-wrinkle transition in soft materials

Creasing and wrinkling instability are two distinct surface instability modes characterized by localized singular folds and continuous smooth undulations, respectively. In this article, we show that the surface of a soft elastomer may develop wrinkles or creases under compression and the action of gravitational force, depending on the magnitude of gravitational force.
