The so-called autonomous adaptive structures are part of a long-term research into shape-memory healing which could impact long-term developments of implantable medical devices, for instance.

ENGADGET: Shape-memory polymer knows when it's hurt, fixes itself

The material uses what the researchers are calling 'shape-memory' polymers and have a fiber optic network embedded within them which acts as the damage sensor as well as the heat delivery system.
