LiveScience (Jan. 25) -- A new method developed by MatSE alumna Jennifer Lewis and MatSE affiliate Ralph Nuzzo could lead to new applications for 4D printing including smart textiles, soft electronics, biomedical devices, and tissue engineering. Inspired by natural structures like plants, which respond and change their form over time according to environmental stimuli, the team has unveiled 4-D-printed hydrogel composite structures that change shape upon immersion in water.
