Figure 4. Effect of the geometrical parameters of the kirigami microstructures on their shape transformation.

Figure 4

A) Snapshots showing the transformation of four kirigami units with different thicknesses (t) of the overhanging kirigami structure at different temperatures. B) Quantitative analysis of the effect of t of the overhanging kirigami structures on the evolution of the length (S0), turning angle (α), and generated void area (Av) at different temperatures. C) Images of three kirigami units with different length ratios of joint width to square edge length (δ/l) at 80 °C. D) Simulation results showing the stress distribution of three basic units with different ratios of δ/l at 80 °C.
