Non-Euclidean Sheets - From Growing Leaves to Self-Morphing Architecture and to Locomotion

I will review the growing scientific field of non-Euclidean sheets, known also as "Self-Morphing". This field suggests theoretical framework and manufacturing approaches that allow the constructions of flat thin sheets of material that, upon induction, shape themselves into desired three-dimensional configurations, much like the way natural growing sheets shape themselves. I will suggest a new way to look at solid sheets – not as passive entities, but as programmable active surfaces and will review the up to date research achievements. I will then focus on two projects: In the first project we study a new way of dynamics – curvature driven locomotion. The second project aims at manifesting the principles of self-morphing in large scale, industrial materials. We develop the basic technique for the construction of flat architectural elements that, upon induction, shape themselves into a desired shape, saving the expensive and wasteful usage of molds.

The Colloquium Ehrenfestii takes place Wednesday evenings starting at 19:30 hours in the Gorlaeus building, lecture hall CM 1.26 (first floor, near main entrance on Einsteinweg 55). Before the Colloquium, there is a common dinner in the Beta Café (far end of the first floor, see map). This dinner starts at 18:00 hours sharp and is free of charge, under the condition that one attends the colloquium and that one has made a reservation before noon on the Tuesday preceding the colloquium.

We count on your presence if you register, please do show up. Meal registrations may close earlier, when 80 persons have signed up.
