I’ve heard of shape memory alloys, but I came across an interesting article in Science Daily, about shape memory rubber titled ‘Retrospective Rubber’ Remembers Its Old Identities:
Researchers at the University of Rochester have developed a shape-memory rubber that may enable applications as diverse as biomedical implants, conformal face-masks, self-sealing sutures, and “smart” labels.
The material, described in the journal Advanced Materials, forms a new class of shape-memory polymers, which are materials that can be stretched to a new shape and will stay in that form until heated, at which time they revert to their initial shape.
