Alloys that can return to their original structure after being deformed have a so-called shape memory. This phenomenon and the resulting forces are used in many mechanical actuating systems, for ...

Shape memory polyurethanes (SMPUs) are a prominent class of smart polymers defined by their ability to recover from a deformed state to their original configuration under specific external stimuli, ...

A study led by Tohoku University, Iwate University, The Japan Aerospace Exploration Agency (JAXA), National Astronomical Observation of Japan, Tokyo City University, and Kyoto University developed a ...

Researchers create biodegradable heart valves using shape-memory polymers and 3D bioprinting for safer cardiovascular procedures.

The current findings utilized the shape memory effect of SMAs to recover the ILMs' shape by adding heat. The researchers hope to build on these findings by using the superelasticity effect of SMAs to ...

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 ...

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 ...
