The technique of keyhole surgery minimises scarring, speeds healing and reduces the risk of infection. However, it is extremely difficult to carry out delicate surgical procedures accurately in a ...

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 at the Georgia Institute of Technology are developing unique polymers, which change shape upon heating, to open blocked arteries, probe neurons in the brain and engineer a tougher spine.

MedShape (Atlanta, GA) has been granted a U.S. patent for a shape memory polymer-based technology used in orthopedic applications. Shape memory polymers can "remember" more than one shape and ...

Researcher Ken Gall uses this thermomechanical test frame to determine the maximum possible shape change of his team's shape-memory polymer. Shape-memory alloys and polymers are the contortionists of ...

Newly developed polymers with shape-memory properties formulated for 3D printing have the potential to advance tissue regeneration and the manufacture of patient-specific implants and prosthetic ...

When stretched or deformed, shape memory polymers return to their original shapes after heat or light is applied. These materials show great promise for soft robotics, smart biomedical devices and ...

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 ...

Researchers at Texas A&M University and the US Army Combat Capabilities Development Command Army Research Laboratory have developed a new family of synthetic materials ranging in texture from very ...

Researchers have developed a shape memory polymer that stores almost six times more energy than previous versions. When stretched or deformed, shape memory polymers return to their original shapes ...
