Despite the great excitements that 2D materials have brought in the past decade, there still are various practical limitations to overcome, while more commercially viable applications need to be identified.  Among such two-dimensional (2D) materials, graphene, the first 2D material discovered, has received the most attention in science/engineering communities owing to its unique physics as well as high commercial potentials.  This talk will discuss a few different approaches to utilize graphene for commercial applications.  In detail, 1) reinforced composite for medical application, 2) graphene metallization, 3) force sensing, 4) incandescent light emission, and 5) RF signal processing will be discussed.  Finally, ongoing efforts on integrating graphene nano-electro-mechanical systems (GNEMS) with conventional CMOS technology, where the benefits of mature CMOS and emerging GNEMS can complement one another, will be presented.
