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 ...

Shape memory materials (SMMs) are featured by the ability to recover their original shape from a significant and seemingly plastic deformation upon a particular stimulus is applied 1. This is known as ...

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 ...

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 ...
