Programmable Deployment of Tensegrity Structures by Stimulus-Responsive Polymers

Abstract Tensegrity structures with detached struts are naturally suitable for deployable applications, both in terrestrial and outer-space structures, as well as morphing devices. Composed of discontinuous struts and continuous cables, such systems are only structurally stable when self-stress is i...
