Towards ultrastretchability, multimodal instability, and static nonreciprocity in kirigami metamaterials
Yafei Wang, Mingchao Liu, Pooya Sareh, Ji Liu, Weicheng Huang
Soft Science, 2025, 5(2): 19 Journal
Kirigami metamaterials, known for their softness, lightness, and stretchability, face challenges in mechanical modeling due to instability and the failure of rigid-body assumptions. This review highlights the need for flexible tensile models and high-curvature designs, and introduces static nonreciprocity as a promising framework to capture their nonlinear, multistable, and asymmetric behavior, paving the way for applications in soft robotics and flexible electronics.

Ziman Zheng#, Xingmei Chen#, Yafei Wang#, Ping Wen, Qingfang Duan, Pei Zhang, Liangjie Shan, Zhipeng Ni, Yinghui Feng, Yu Xue, Xing Li, Lin Zhang, Ji Liu
Advanced Materials, 2024, 36(41), e2408538 Journal
We developed a self-growing hydrogel bioadhesive patch that instantaneously adheres to biological tissues and progressively strengthens over 120 h to mechanically contract chronic wounds and enhance healing efficacy.
Strain stiffening retards growth instability in residually stressed biological tissues
Yafei Wang, Yangkun Du, Fan Xu
Journal of the Mechanics and Physics of Solids, 2023, 178, 105360 Journal
This study examines how strain-stiffening in biological tissues influences growth and remodeling, particularly in airways. Using a growing tubular structure with collagen-induced strain-stiffening, the research incorporates the nonlinear hyperelastic Gent model and initial stress symmetry theory. Results show that strain-stiffening delays growth instability at moderate strains and prevents it at low strains, maintaining stable epithelial tissue. These findings suggest that strain-stiffening can slow instability in biological growth and remodeling, with implications for clinical interventions in chronic inflammatory airway diseases.
Mechanics of strain-limiting wrinkled kirigami for flexible devices：High flexibility, stretchability and compressibility
Yafei Wang, Changguo Wang

We develop a theoretical framework to describe the buckling behavior of ultrastretchable kirigami metastructures, validated through experiments and simulations for applications in stretchable electronics and energy harvesting.
Geometry-dependent stretchability and stiffness of ribbon kirigami based on large curvature curved beam model
Yafei Wang, Changguo Wang, Huifeng Tan
International Journal of Solids and Structures, 2020, 182: 236–253 Journal
A dimensionless analytical model based on the large curvature curved beam theory is proposed to predict the normalized stiffness and stretchability of ribbon kirigami. Theoretical predictions are validated by experiments and simulations, offering design insights for kirigami-based structures.
