Shape Changing Smart Materials

Shape-changing smart materials are materials and products which are able to reversibly change their shape in response to one or more stimuli like the effect of light, temperature, pressure, an electric or magnetic field, or a chemical stimulus. There are materials and products that are able to change their shape without changing their dimensions and other materials and products that retain their shape but change their dimensions. Some are also able to change both parameters at the same time.
