Nature : Nitinol is an alloy of nickel and titanium that “remembers” a previous shape when heated. Harvard’s Robert Wood has incorporated tiny nitinol-based hinges into flat, pre-sectioned sheets of a glass fiber composite. When electricity is sent through the hinges, they warm up and fold the sheet into a boat, airplane, or other preprogrammed origami object .
