Discussing a New 3D-Printing Method That Enables Color-Changing, Stress-Responsive Materials

On this episode, Professor Shu Yang and Alicia Ng of the University of Pennsylvania join me on the podcast to discuss their latest research work. Their team has successfully developed a cutting-edge method to 3D print cholesteric liquid crystal elastomers (CLCEs), opening the door to dynamic, color-changing materials that can respond to mechanical stress. This work paves the way for groundbreaking applications in smart sensing, displays, and robotics. At the heart of this advancement are CLCEs – soft, rubbery materials capable of changing color when subjected to mechanical stress. Shu Yang is a materials scientist and Professor of Engineering and Applied Science and Chair of the Department of Materials Science and Engineering at the University of Pennsylvania.  Alicia Ng is a Ph.D. student in Materials Science and Engineering (MSE) and is the lead author of this study.
