Morphing Materials

​

​We are inspired by the hygroscopic movements of plant organs, such as those seen in the pine cone and other seed dispersal units. These systems are particularly interesting in that the organs are both structure and motor in one, the motion being controlled by the geometric arrangement of constituent tissues with different swellabilities. The focus of our group in this direction is to understand and develop models (both theoretical and physical) of 3D motion. We work closely with biologists to understand the opening mechanisms of plant-based actuators. We then aim to apply the design principles learnt to new biomimetic composites (together with synthetic chemists) and create prototypes using advanced 3D (or 4D) printing technology.
