Unconventional Manufacturing of 3D Micro- and Mesostructures: From Strain-Engineered Growth to Mechanically Guided Assembly
Speaker: Dr. Hangbo Zhao, Assistant Professor, University of Southern California

Abstract: The growing availability of methods for 3D manufacturing has implications across diverse areas ranging from energy systems to microelectronics, yet few techniques offer the necessary capabilities in geometric complexity, materials compatibility and design versatility. In this talk, I will discuss two novel manufacturing approaches to creating 3D functional material systems that are not feasible by conventional manufacturing methods: 1) strain-engineered growth of complex 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 enables the formation of hierarchically structured surfaces with tailorable mechanical and interfacial properties for controlling liquid wetting and adhesion. Next, I will describe novel manufacturing technologies that exploit structural buckling and local twisting to create morphable 3D micro- and mesoscale structures, and show their applications as optical metamaterials and as electronic scaffolds in tissue-on-chip systems.
