Color-changing materials

The research, led by Juan de Pablo, Liew Family Professor of Molecular Engineering, was published in the journal Science Advances. “Now the possibilities are really open to the imagination,” de Pablo said. “Imagine using these crystals in a textile that changes color based on your temperature, or changes color where you bend your elbow.” Such a system could also be used to measure strain in airplane wings, for example, or to discern minute changes in temperature within a room or system. Changes in color provide an excellent way to measure something remotely, without the need for any sort of contact, de Pablo said.
