Researchers from Penn Engineering, Harvard University, Duke University, UC Berkeley, and Lawrence Livermore National Laboratory have developed a method to 3D print cholesteric liquid crystal elastomers (CLCEs). The team’s work, published in Advanced Materials, enables the creation of color-changing materials that respond to mechanical stress. CLCEs are soft, rubbery materials that can manipulate light similar to beetle […]
