About The Lab

Soft materials are capable of large deformation, and have mechanical properties comparable to those of biological tissues. Recent developments in soft materials are enabling the rise of soft robotics, stretchable electronics, and biomechatronics. These new fields are profoundly altering the interactions between human beings and machines. Through the integration of analytical modeling, computational simulation and experiment, our group aims to investigate the fundamental physics and mechanics of soft materials, such as their constitutive relation, nonlinear deformation, instability, and fracture. On the other hand, our group strives to develop new materials, structures, and functions for soft robotics and stretchable electronics.
