Abstract Soft materials, such as polymers, foams and hydrogels, can deform easily and to very large strains. Their shapes and sizes can vary greatly even if the applied forces are small. Different from “hard materials”, soft materials have very different and unique properties, which may have potential applications in various fields but have been much less explored. This offers people great opportunities for making breakthrough discoveries and inventions in engineering and medicine. Moreover, a combination of soft and hard materials could enable people to develop unprecedented functions of machines, structures and devices, for example, self-organized patterns and soft robotics and self-folding structures. In this talk, I will present some work we have done in the field of mechanics and physics of soft materials and nanomaterials, particularly the mechanical instability of thin film-substrate system, the printed, flexible and stretchable electronics, and the innovative biomedical devices. I will first describe how we use numerical and experimental methods to identify the instability modes and the scaling laws for generating tunable surfaces patterns. Then, I will demonstrate how to harness mechanical instabilities and large deformations from soft materials to develop stretchable supercapacitors and novel medical devices. Finally, I will show our recent efforts in developing robust, smart and sustainable packaging system with engineered materials and technologies.
