Surface instability and morphological evolution of such soft materials as gels and biological tissues is a major concern in a wide diversity of fields, e.g., soft lithography, metrology, flexible electronics, and biomedical engineering, and therefore have received much attention.In this talk, surface instability of soft materials and biological tissues are discussed within the framework of continuum mechanics.Firstly, a generic method is presented for analyzing the surface stability of a thin film resting on a substrate with arbitrary geometry.Secondly, the growth and buckling of mucosas that commonly line organs and cavities throughout the animal body are analyzed theoretically, numerically and experimentally.Finally, the surface wrinkling of soft core-shell matters induced by swelling or shrinking is investigated.The results demonstrate that the evolution of the sphere may be characterized by a process of smooth surface, buckyball-like wrinkling pattern, and then undergoing a wrinkling-to-fold transition into labyrinth-like folded patterns, in agreement with our experimental observations.
