报告内容摘要：
     Curvilinear electronics is electronics with performance equal to established technologies that use well-developed inorganic semiconductor materials, but in lightweight, foldable and curvilinear format.  Realization of curvilinear electronics would enable many innovative biological and medical applications, such as electronic eye cameras (Nature, 2008), personal health monitors, curvilinear displays, smart surgical gloves and optoelectronics.  Advanced methods are now available for conformally wrapping planar, silicon-based electronics circuits onto complex, curvilinear surfaces (Small, 2009).  Buckling physics of circuits configured into mesh geometries consisting of silicon islands interconnected by narrow polyimide ribbons leads to out of plane displacements across different parts of the curvilinear surface, in a way that accommodates strains associated with wrapping.  A simple and robust mechanics model is established to predict the buckling patterns of interconnect bridges for arbitrarily axisymmetric curvilinear surfaces. (Soft Matter, 2010)  Similar technology is recently used to build the next generation skin sensors/devices that achieve conformal contact to the skin, and adequate adhesion based on van der Waals interactions alone, in a manner that is mechanically invisible to the user (Science 2011).

报告人简介：
    Shuodao Wang is a Ph.D. candidate of Mechanical Engineering at Northwestern University.  He has published 1 book chapter and 12 papers in archival journals, including multi-disciplinary journals (Science, Nature, Nature Materials, Energy & Environmental Science), material journals (Advanced Functional Materials, Soft Matter), nano journals (Small), and physics journals (Applied Physics Letters, Journal of Applied Physics).  His recent work has been reported by many popular media such as ABC, BBC, Discover, Nature News & Views, Chicago Tribune, MIT Technology Review, Scientific American, US News & World Report, The Economist, and United Press International, etc.  Some of his work attracted lots of attentions in academia and is being used as the course materials for an undergraduate class taught by Prof Pedro Reis at MIT.  His recent awards include the Chinese Government Award for Outstanding Self-financed Students Abroad (2010), the NSF Fellowship for soft materials (2010) and Energy Challenge and Nanotechnology (2009), Walter P. Murphy Fellowship (2007-2010) and Ryan Fellowship for Nano Science/Technology (2009-2011).
