Multistable shape-reconfigurable metawire in 3D space

Reconfiguring to complex 3-dimensional (3D) target shapes from an easily-manufactured low dimensional initial configuration is crucial for many versatile materials/structures which require tunable functions and multiple applications. However, the energy-efficient morphing strategy to realize such transdimensional shape-reconfiguration remains largely unexplored. Here a 1-dimensional (1D) wire-shaped multistable metastructure, named metawire,...
