SEAS researchers create shape-shifting architectures that mimic plant movements. A team of scientists at the Wyss Institute for Biologically Inspired Engineering at Harvard University and the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) has evolved their microscale 3-D printing technology to the fourth dimension, time.

Inspired by natural structures like plants, which respond and change their form in response to environmental stimuli, the team has unveiled 4D-printed hydrogel composite structures that change shape when immersed in water.
