Engineers from MIT and Singapore University of Technology and Design are 3D-printing structures based on shape-memory polymers that “remember” and spring back to their original shapes when heated to a certain temperature. The structures can be used for medical applications as tiny drug capsules that open upon early signs of infection. Other applications include biomedical devices, deployable aerospace structures, and shape-changing photovoltaic solar cells. Check out the videos in the article.
