From Functional Nanomeshes to Advanced Soft Microsystems
New form of materials can often enable new device and system applications. In this talk, I will highlight our group's recent work under this motivation in two synergistic areas. Firstly, by stacking individual layers of polymer, metal, and low-impedance coating reliably in a same nanomeshed pattern, the final multilayer multifunctional nanomeshes achieved system-level performance from all individual layers, in addition to nanomesh advantages. Compelling demonstrations from this multifunctional nanomesh approach include high-performance transparent and flexible neuroelectrode arrays, which has been recently validated in vivo. The second part of my talk will introduce our recent concept on semiconductor nanomeshes. By making a silicon film into homogeneous nanomeshes, we achieve high mobility semiconductor that is intrinsically stretchable to conventional microelectronic layouts. Together, our work demonstrates that nanomeshing is a unique way of transforming microelectronics for emerging applications.
Hui Fang received his B.S. degree in 2009 from Tsinghua University and his Ph.D. degree in 2014 from the University of California, Berkeley, both in Materials Science and Engineering. He was then a postdoctoral fellow at the University of Illinois, Urbana-Champaign from 2014 to 2016. He joined Northeastern University in August 2016 where he is currently an Assistant Professor in Electrical and Computer Engineering, with affiliate appointments in Bioengineering and Mechanical & Industrial Engineering. Fang’s research interests encompass the fields of materials science, electrical engineering, and biomedical engineering. His research has been recognized multiple awards including an NSF CAREER Award (2019) and a CDMRP Epilepsy Risk Factors Award (2018).
