Figure Lengend Snippet: Motion characteristics and design optimization of bistable structures. A) Simulation results of the force‐displacement curve and energy landscape of the DCBB. The inset image is the model used for FEA simulation. B) Simulation results of the force‐displacement curve and energy landscape of the VSBB. The inset image is the model used for FEA simulation. C) Geometrical design (left) and 3D‐printed model (right) of a VSBB. D) Force‐displacement test results of VSBBs with the initial inclination angle of 12 (the dashed lines indicate testing performed from SP2). Three identical samples for each geometrical condition are tested. E) Comparison of force‐displacement curves obtained from experiments and theoretical calculations. F) The average displacements from SP1 to the snap‐through point (bottom), the total displacements from SP1 to SP2 (middle), and the displacements from SP2 to the snap‐through point (top) of the bistable structures with different geometrical parameters from force‐displacement tests.

Article Snippet: To compare the properties of DCBB and VSBB, we simulated their motion pattern using FEA software ABAQUS (see Supporting Text 1 and Figure , Supporting Information).
