Figure 2

Time-resolved 3D shape morphing by photo-triggered curvilinear strain engineering. (a) Experimental results of the thermal images obtained by the FLIR camera (the scale bar: 2 cm). (b) FEM simulation results showing the temporal shape morphing and surface temperature distribution. Shown is PS film with a radial pattern (N = 8) and a non-patterned central facet region (D = 2 cm). The enlarged final image is presented to describe the formation of anticlastic curvature in the patterned regions by spatial stress competition effects between patterned and non-patterned regions. See Supplementary Movie 1 in the Supporting Information.
