Recent advances in mechanics and materials provide routes to integrated circuits that can offer the electrical properties of conventional, rigid wafer-based technologies but with the ability to be stretched, compressed, twisted, bent and deformed into arbitrary shapes.  Inorganic electronic materials in micro/nanostructured forms, intimately integrated with elastomeric substrates offer particularly attractive characteristics in such systems, with realistic pathways to sophisticated embodiments.  Mechanics plays a key role in this development by identifying the underlying mechanism and providing analytical solutions to guide design and fabrication. I will present our research on stretchable silicon [1] and its applications to stretchable and foldable circuits [2], electronic-eye camera [3,4], semi-transparent and flexible LED [5], epidermal electronics [6], dissolvable electronics [7,8], injectable, cellular-scale optoelectronics [9], and soft, microfluidic assemblies of sensors, circuits and radios [10].  Review of stretchable electronics has been published [11].

Huang Yonggang received his bachelor’s degree from Peking University in 1984 and earned his doctoral degree from Harvard University in 1990. He is currently the Walter P. Murphy Professor at Northwestern University. He was elected academician of the European Academy of Sciences and Arts in 2010, as well as academician of the U.S. National Academy of Engineering and foreign academicians of the Academia Europaea and the Chinese Academy of Sciences (CAS) in 2017. His research enjoys the highest citation rate in the USA in the field of solid mechanics among the 75-year-old or below academicians from the Academy of Sciences or the Academy of Engineering. He is also the most highly cited researcher in the field of world solid mechanics over the past two decades (1998-2017), and the most highly cited Chinese researcher up till now in this regard.

 

Huang has been working on mechanics of materials and electronic devices. His major scientific achievements include: 1) pioneering the field of stretchable inorganic electronic devices; and, 2) proposing a theory of mechanism-based strain gradient (MSG) plasticity.

 

He has made substantial contributions to the development of China's mechanics and flexible electronics disciplines. In terms of professional talent cultivation, he trained 17 Chinese doctoral students and postdoctoral researchers in the United States, who have returned home, including one honored with Chief Scientist for National 973 Program, three with National Science Fund for Distinguished Young Scholars, six with Outstanding Youth Science Foundation, two with Thousand Talent Program for Young Outstanding Scientists, two with Qiu Shi Outstanding Young Scholars, one with MIT Technology Review Youth Inventor, one with International Engineering Science Association Young Scientist Award, one with Eshelby Young Teacher Award of International Mechanics, and one with Sia Nemat-Nasser Early Career Award from ASME (American Society of Mechanical Engineers) on Materials. In addition, he jointly trained nine postdoctoral fellows and 28 doctoral students (three students won Top 100 National Excellent Doctoral Dissertation Award) with universities such as Tsinghua University, Zhejiang University, Harbin Institute of Technology, Tongji University, Dalian University of Technology, and Nanjing University of Aeronautics and Astronautics. Based on his planning, the Advanced Mechanics and Materials Research Center and the Soft Matter Research Center (SMRC) were established in Tsinghua University and Zhejiang University respectively. Two 973 programs have been approved under his leadership, thus leading the development of domestic stretchable inorganic electronic devices.
