will present a talk entitled:

“Polymer microstructures that see and think: configuring enhanced fields of view and computational ability in soft materials”

Abstract:  The emerging field of “materials that compute” aims to mimic the intelligent responsiveness of biological systems – without the need for external electronics or processors. Examples are tactility, vision, camouflage, contractility and flight where complex natural sensors such as skin, eye and muscle seamlessly adapt to environmental stimuli through exquisitely programmed response sequences. My research group contributes to this objective by applying our understanding of unusual (nonlinear) forms of light and their extraordinary behaviours in soft light­responsive polymer materials. In this talk, I will describe how we harness these properties to develop three interlinked research themes: (i) soft materials that perform computing operations ­ such as addition and subtraction ­ by exploiting the interactions of nonlinear light beams; (ii) artificial compound eyes assembled from microscopic light­guides and (iii) prismatic 3­D printing, which photo­inscribes objects within seconds. Progress in (i ­ iii) will allow us to design and devise 3­D dynamic, light­responsive objects that can image wide panoramic spaces, respond to touch and process interactions by performing local computations with incident light.
