In particular the talk will highlight our work on flexible electronics\, zero-power devices\, monolayer memory (atomristors)\, non-volatile RF switches\, and wearable tattoo sensors. Non-volatile memory devices based on 2D materials are an application of defects and is a rapidly advancing field with rich physics that can be attributed to sulfur vacancies or metal diffusion. Atomistic modeling and atomic resolution imaging are contemporary tools under use to elucidate the memory phenomena. Likewise\, from a practical point\, electronic tattoos based on graphene have ushered a new material platform that has highly desirable practical attributes including optical transparency\, mechanical imperceptibility\, and is the thinnest conductive electrode sensor that can be integrated on skin for physiological measurements. Much of these research achievements have been published in nature\, IEEE and ACS journals\, and widely covered by the news media including Time magazine\, BBC\, Nature news\, IEEE spectrum\, and several dozen media outlets. \nReferences:\n[1] Akinwande\, et al.\, “Graphene and 2D Materials for Silicon Technology\,” Nature\, 2019.\n[2] X.
