Shape memory materials that can revert back into a desired form after being bent, twisted and stretched are finding their way into a number of applications, ranging from sports bras to more efficient ...

Ryan Hayward's self-folding crane begins as a flat, trilayer sheet. The middle pNIPAM hydrogel layer swells as the water around it is heated, and the folding is guided by slits patterned into the more ...

Shape memory polymers (SMPs) are a remarkable class of stimuli‐responsive materials capable of undergoing substantial deformation and subsequently recovering their original shape when exposed to ...

Polymers that exhibit shape-memory effect (SME) are an important class of materials in medicine, especially for minimally invasive deployment of devices. Professor Subbu Venkatraman and his group from ...

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