Abstract
Shape memory is the ability of a material to remember its original shape after deformation and return to its original shape upon activation of the shape memory effect by the application of an external stimulus. Shape-memory polymers (SMPs) are an emerging class of active polymers that have dual-shape capability and belong.to the group of 'actively moving' polymers. They can actively change from a shape A to a shape B. SMPs are unique class of polymers which soften and harden Quickly and repetitively on demand. This feature provides the ability to temporarily soften, change shape, and harden back to a solid structural state. They have applications as environmental tracking sensors, valves, healable vehicle impact devices, smart textiles, pressure sensors and biomedical devices.Downloads
