Chameleon-like robots can change color and blend into their surroundings

The study was published in Nature Communications. Producing flexible electronics consists of expensive tools and several scientific steps many times. Therefore, an easy and versatile fabrication strategy to support the increasing demand for flexible electroluminescence devices in technological and optical applications is needed. Ji Liu and researchers display an approach to fabricating flexible electroluminescence devices through multi-material 3D printing. They formulated ion conducting, electroluminescent and insulating inks suitable for 3D printing, which they could use to create facile, on-demand, flexible, and stretchable electroluminescent devices.
