Reversible shape change is a highly desirable property for many biomedical applications, including mechanical actuators, soft robotics and artificial muscles. Some materials can change size or shape ...

Engineers at the NIST Center for Nanoscale Science and Technology (CNST) have developed a new technique for fabricating high aspect ratio three-dimensional (3D) nanostructures over large device areas ...

A new use for the ubiquitous PowerPoint slide has now been discovered: Producing self-folding three-dimensional origami structures from photocurable liquid polymers. Researchers at the Georgia ...

A grayscale pattern used to create a self-folding flower is projected into a glass container. Light from the pattern forms a solid polymer which is differentially crosslinked, creating stress in the ...
