Earwig fan folding with thick panels.

To address the challenges of scaling biologically inspired deployable structures, particularly focusing on translating the compact folding mechanism of earwig hind wings into human-scale engineering applications. Biological folding systems often lose structural efficiency at larger scales due to scaling laws, such as the square-cube law, making thickness and strength critical considerations. We analysed the geometric principles underlying the earwig () wing-folding mechanism and developed a parametric design methodology to replicate these principles for thick-panel materials.
