Symposium Technical Description

Soft materials are ubiquitous in nature, from biopolymers, cells, and tissues to organs. In recent years, soft materials have been intensively explored in different engineering applications, ranging from haptic devices to soft robotics, from flexible electronics to biomimetic systems. Fundamental studies of the deformation mechanisms of soft materials and optimal designs in different applications urgently need robust methods for material characterization. In this program, the co-organizers plan to invite both theoretical and experimental studies on mechanical properties of soft materials such as gels, elastomers and biological materials. We appreciate novel techniques that are applied to study the microstructures and macroscopic behaviors of soft materials, new devices for imaging, processing and measurement, and theoretical and computational models inspiring new ways of material characterizations. We aim to sharing and advancing our knowledge and technology in this area.
