4D-printed materials can be stiff as wood or soft as sponge

Imagine smart materials that can morph from being stiff as wood to as soft as a sponge - and also change shape. Rutgers University-New Brunswick engineers have created flexible, lightweight materials with 4D printing that could lead to better shock absorption, morphing airplane or drone wings, soft robotics and tiny implantable biomedical devices.
