MEAM Seminar: “Kirigami: Programming Cutting and Folding from Microscale to Meter Scale”
September 28, 2021 at 10:00 AM - 11:30 AM
Programmable shape-shifting materials can take different physical forms to achieve multifunctionality in a dynamic and controllable manner. By introducing holes and cuts in 2D sheets, we demonstrate dramatic color and shape change and super-conformability via collapsing or expanding of the hole arrays in the micro- and macroscales. When choosing the cuts and geometry correctly, we show folding into the third dimension, known as kirigami. By programming the geometry of cuts and folding angles, we explore their potential applications in water harvesting, super-stretchable and shape conformable medical devices.

Shu Yang is Joseph Bordogna Professor of Engineering and Applied Science and Chair of the Department of Materials Science & Engineering, and Professor of Chemical & Biomolecular Engineering at University of Pennsylvania. Her group is interested in synthesis, fabrication, and assembly of soft materials and composites, and use of geometry to create smart and bioinspired materials that are highly stretchable, super-conformable, and shape transformable for potential applications, including coatings, adhesives, structural colors, sensors, actuators, and tissue scaffolds for soft robotics, biomedical devices, and energy efficient building components. Yang received her B.S. degree from Fudan University and Ph. D. degree from Cornell University. She worked at Bell Laboratories, Lucent Technologies as a Member of Technical Staff before joining Penn. She received George H. Heilmeier Faculty Award for Excellence in Research from Penn Engineering. She is a Fellow of Materials Research Society (MRS), Division of Soft Matter (DSOFT) from American Physical Society (APS), Division of Polymeric Materials: Science and Engineering from American Chemical Society (ACS), and National Academy of Inventors. She was elected as Innovators under 35 by MIT’s Technology Review.
