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 behavior and light emission of suspended carbon structures, possible application of carbon based nano electro-mechanical devices will be suggested. Carbon based ultra-sensitive mass detector will be suggested for one of the promising applications of our devices and our recently accepted HFSP project based on this subject will be introduced at the end of presentation.
