Shape-morphing metamaterials

Nature Reviews Materials
Mechanical metamaterials leverage geometric design to achieve unconventional properties, such as high strength at low density, efficient wave guiding, and complex shape morphing. The ability to control shape changes builds on the complex relationship between geometry and nonlinear mechanics, and opens new possibilities for disruptive technologies ...

Shape morphing mechanical metamaterials through reversible plasticity

Science Robotics, 2022
Biological organisms such as the octopus can reconfigure their shape and properties to perform diverse tasks. However, soft machines struggle to achieve complex configurations, morph into shape to support loads, and go between multiple states reversibly. Here, we introduce a multifunctional shape-morphing material with reversible and rapid

Shape-morphing architectures actuated by Janus fibers

Soft Matter, 2020
We investigate experimentally and theoretically the variety of shape transitions in structures actuated by Janus fibers. Such structures have a fast response time, well-controllable mechanics, and mimic an elementary cell of the web architecture.

Shape morphing hinged truss structures

Smart Materials and Structures, 2009
Truss structures are widely used for the support of structural loads in applications where minimum mass solutions are required. Their nodes are normally constructed to resist rotation to maximize their stiffness under load. A multi-link node concept has recently been proposed that permits independent rotation of tetrahedral trusses linked by such a ...

Directional Shape Morphing Transparent Walking Soft Robot

Soft Robotics, 2019
Transparency in electronics can provide extra functionality and esthetic impression. Transparency plays an important role in accurate soft robot control because one can directly observe target surface condition that is usually blocked by a robot's body.

Automatic shape morphing for Chinese characters

SIGGRAPH Asia 2012 Technical Briefs, 2012
How to automatically implement shape morphing for Chinese characters represented in different styles is a challenging task. In this paper, we propose a novel method to solve this problem. Specifically, we first generate the shape template, which includes a skeleton, strokes, key points, and connection triangles, for every character in a standard ...
