The Flexible Equipment Innovation Center (iFlex) of the School of Materials Science and Engineering at Nanyang Technological University (NTU) in Singapore was founded in January 2017 by the University and Stanford University in the United States, focusing on the development of flexible electronics (devices and devices). In a recent study, they have made some progress, using fused deposition 3D printing technology and shape memory composites (composed of shape memory polymers and carbon black with high photothermal conversion efficiency). Photosensitive element.
Such 3D printed photosensitive elements are not only more complex than ordinary stimuli-responsive devices having only a planar or tubular structure, but also rapidly respond to external light stimuli, returning from the current shape to the original shape. It is worth mentioning that this shape memory behavior is affected by material thickness and optical density, and this effect can be quantified and calculated. Even more surprising is that sunlight can also effectively stimulate this behavior.
Researchers say the new results may be an important enabler for the development of bionic smart devices and flexible robots.
