Limitations of Classical Method
Different types of thin coatings such as soft metals, organic compounds such as selfassembled monolayers, bi-layer and multilayer hard coatings, diamond-like carbon films and nanostructured coatings can be used to reduce friction and wear in microdevices. Unfortunately, despite reports of numerous proposed coatings, an optimum method for reducing the friction and wear of these devices has not yet been identified.

Abstract
Background
Graphene has received significant attention due to its combination of remarkable mechanical, thermal, chemical and electrical properties. Furthermore, due to its superior strength, graphene has great potential for use as an ultra-thin protective coating for various precision components. In this paper, the latest developments in tribological applications of graphene, theoretical simulations of graphene friction and preparation methods are reviewed. It is shown that various graphene coatings can be successfully used to decrease friction and wear in nano-, micro- and macro-mechanical applications. However, the conditions under which graphene serves as an effective protective coating depends on the operating parameters. A comprehensive review is provided with the aim to assess such characteristics of graphene.

New Breakthrough of Tribology
The combination of the remarkable mechanical, thermal, chemical and electrical properties of graphene sheets and their relatively low production cost distinguish them from other materials used for nano-electromechanical applications. Thus, graphene is considered as a promising material for future applications in nanoelectronic and miniaturized devices.
