Covalently anchored hydrogels show spontaneous formation of surface instabilities. Although surface instabilities on polymeric and elastomeric films have been extensively studied, fewer studies focused on the formation of instability patterns in hydrogels. The current and prospective applications have led to a surge in the interest in the study of surface instabilities in hydrogels. These applications include cell culture models, adhesives and optical devices, and stimuli-responsive soft actuators. This chapter gives a detailed review on the recent progress in the formation of surface instabilities in confined hydrogels. A fundamental understanding of surface instabilities in different constructions of hydrogel films is provided. The fabrication approaches to create wrinkles on hydrogel surfaces are classified based on the types of stimuli and the hydrogel systems. Finally, several examples in which surface instabilities in hydrogels have been employed are presented.
