Shape-memory metals, which can revert from one shape to a different one simply by being warmed or otherwise triggered, have been useful in a variety of applications, as actuators that can control the ...

With 4D printing, the objects can change shape or properties using external stimuli such as temperature, light, pH, magnetic field, electricity, and moisture. Additionally, the changes in shape or ...

A recent article published in Small Science introduces fully bioderived, four-dimensional (4D) printable shape memory polymers (SMPs) with linear tunability and remotely controlled actuation ...

MINNEAPOLIS / ST. PAUL (11/17/2021) — An international team of researchers from the University of Minnesota Twin Cities and Kiel University in Germany have discovered a path that could lead to ...

Engineers have created shape-memory materials made of ceramic rather than of traditional metal. The development opens a new range of applications, especially for actuators in high-temperature settings ...
