Paragraph starter
The conformability of flexible materials on non-developable surfaces, such as spheres, presents a significant design challenge. Research by Liu et al. (2023) demonstrates that introducing radial slits into flexible sheets can dramatically improve their ability to conform to spherical surfaces, increasing conformability from approximately 40% to over 90%. This finding offers a practical design strategy for engineers and designers aiming to integrate flexible components onto curved substrates, moving beyond the limitations of purely stretchable materials.
