In this presentation, physical properties and possible applications of carbon based nano electro-mechanical devices

(NEMS) will be introduced. Our research started from carbon nanotube based nano electro-mechanical relay

structure and expanded to graphene-based xylophone and drum like devices. Micro contact transfer method is

applied to realize the suspended nano structures with various electrodes under the nano materials. Recently

developed pick-up and transfer technique made us possible to fabricate various stacking and suspended nano

structures. After introducing some interesting physical properties, such as basic mechanical switching and

resonance behaviour and light emission of suspended graphene structures, possible application of carbon based

nano electro-mechanical devices will be suggested. Graphene based ultra-sensitive mass detector will be suggested

for one of the promising applications of our devices and our recent research project on single protein sequencing

using graphene-based mass detector will be introduced at the end of presentation.
