“Developing Next-Generation Electronics: From High Performance Flexible Electronics to 3D Curvilinear Devices”

Abstract: Innovative manufacturing technologies are critical in building next-generation electronics devices, when we are migrating from conventional electronics to high performance flexible electronics and 3D curvilinear devices, which hold promise in areas of healthcare, consumable electronics, etc. In this talk, I will first briefly introduce recently advances in soft flexible electronic and then discuss the heterogeneous integration of single crystal semiconductor for developing next generation high performance flexible electronics. Examples including an ultra-thin (a few microns thick) flexible Si camera and an artificial skin with autonomously color camouflaging ability will be demonstrated. Furthermore, to develop 3D curvilinear shaped devices, a new manufacturing approach, namely conformal additive transfer printing, will be discussed. Different type of 3D curvilinear device such as smart contact lenses with integrated sensors and electronics for multi-functionalities will be demonstrated. Finally, I will conclude my talk with a discussion of some of our current research activities and future research directions.
