Fig. 2: Design strategy for creating non-volatile reconfiguration.

a SEM image of an array of the curved-up shape with orthogonal curvature through anti-symmetric bending. The white dashed line surrounds two of the folded shape. The scale bar is 100 μm. b SEM (1–4) and optical images (5–8) of eight samples before and after shape morphing with geometric parameters shown in the attached table. W2/W1 and W2/L2 represent the ratio of the upper layer width to lower layer width, and upper layer width to length, respectively. The scale bar is 50 μm. c The variations of \(\kappa _y/\kappa ^i\) (left axis) and \(\kappa _x/\kappa ^{ii}\) (right axis) versus the time from FEM. d Phase diagram of favorable shape-morphing status related to W2/W1 and W2/L2. Gray circles are the results of experiments in b. Yellow (pure bending), red (anti-symmetric bending), and green (cross-ply bending) dots are the results from FEM.
