Multiscale Heterogeneous Polymer Composites for High Stiffness 4D Printed Electrically Controllable Multifunctional Structures (Adv. Mater. 8/2024)

Abstract

4D Printing Stiff, electrically controlled morphing structures are built by 4D printing new heterogeneous multiscale polymer composites. This enables active autonomous 3D structures with self-sensing actuation and unprecedented levels of actuation stress and specific force. Integrating these materials with lattice designs enables large scale complex 3D surfaces that are load-bearing, culminating in the crawling multigait robotic lattice featured here.
