Reza has used different arrangements of bi- and multi-layers of shape memory (SMP) and hyperelastic polymers to program four basic modes of shape-shifting including self-rolling, self-twisting (self-helixing), combined self-rolling and self-wrinkling, and wave-like strips. Additionally, Reza worked on the thermomechanical characterization of different polymers such as natural rubbers, PVC, natural rubber/styrene-butadiene rubber, etc. to obtain their stress-strain curves under different conditions.
