Understanding shape-shifting polymers (w/ Video)

(PhysOrg.com) -- Shape-memory polymers are not a new discovery, as anyone who has played with Shrinky-Dinks or who has used heat-shrink tubing for wires in an electronic circuit can testify. But now, thanks to new analysis by researchers at MIT, the behavior of these interesting materials has been mathematically modeled in detail, which should make it easier to use the materials in new ways; potential applications include implantable biomedical devices and space structures that could be launched in a compact form and then unfurled once in orbit.
