4D Printing of Shapeshifting Devices
Researchers at the Wyss Institute have mimicked a variety of dynamic shape changes like those performed by tendrils, leaves, and flowers in response to changes in humidity or temperature with innovative 4D-printed hydrogel composites. These materials may be used to fabricate medical devices that take on programmed shapes when placed in contact with body fluids, as well as smart textiles, responsive building materials and novel electronic sensors and actuators.
