Micro/nanoscale 4D printing revolution: Manufacturing high-resolution transformable 3D structures

Have you ever imaged high-resolution 3D structures at the micro/nanoscale that react dynamically to their surroundings? The 4D printing technology is changing the game by using smart materials that exhibit remarkable shape deformation in response to external stimuli, showing the enormous potential for use in biomedicine, flexible electronics, soft robotics, and aerospace.
