It is programmed to hold a temporary shape until it is triggered by heat to return to its original form.\nThe individual strands are connected by altering the molecular linkers to form different shapes. Researchers were able to adjust the material's stability and set the point when the shape change is triggered.<\/p>"},{"type":"img","id":"img-uid-1457967432328","data":"56e6d1bff3010"},{"type":"txt","id":"rich_1457967145213","data":"The research team led by Chemical Engineering Professor Mitch Anthamatten at the University of Rochester created a material that undergoes a shape change that can be triggered by body heat alone. \"Tuning the trigger temperature is only one part of the story,\" said Anthamatten.\n\nThese materials are engineered to store large amount of elastic energy.
