Abstract: The growing availability of methods for three-dimensional (3D) manufacturing has implications across diverse application areas from energy systems to microelectronics, yet few techniques offer the necessary range of capabilities in geometric complexity, materials compatibility and design versatility. In this talk, I will discuss two distinct types of advanced manufacturing approaches to creating 3D functional material systems that are not feasible by conventional manufacturing methods: 1) strainengineered growth of self-organized 3D carbon nanotube microarchitectures, and 2) mechanically guided 3D assembly of a broad range of functional materials and electronics. I will show how strain-engineered growth of carbon nanotubes, in combination with conformal coatings, enables direct formation of hierarchically structured surfaces with tailorable mechanical and interfacial properties for controlling liquid wetting and adhesion. Then I will describe novel manufacturing technologies that exploit structural buckling and local twisting to create morphable 3D mesoscale structures in diverse advanced materials, for applications including optical metamaterials and microphysiological platforms for tissue engineering and biomedical research. I will conclude by discussing new opportunities in developing multifunctional, adaptive material systems.

Bio: Dr. Hangbo Zhao is currently a postdoctoral researcher in the Center for Bio-Integrated Electronics in Prof. John Rogers’ group at Northwestern University, where he works on multifunctional 3D materials systems and bio-integrated electronics for applications in tissue engineering and healthcare. He received his Ph.D. degree in the Department of Mechanical Engineering at MIT in 2017, supervised by Prof. A. John Hart. His Ph.D. thesis focused on developing engineered, hierarchical surfaces for controlling liquid wetting and adhesion.
